To what extent did Malthus€™ philosophy influence Essay

To what extent did Malthusâ‚ ¬Ã¢â€ž ¢ philosophy influence Englandâ‚ ¬Ã¢â€ž ¢s policies towards Ireland preceding and during the Great Famine Cite 3 specific examples. Follow MLA protocol - Essay Example There were of course different interpretations of what constituted progress: Rousseau, Voltaire, and later Marx all had their ideas about it. One such theorist concerning the best means for improving the lot of all men was Thomas Malthus. His philosophy on the nature of man would later have a profound effect on English policy and attitudes toward Ireland. Malthus did not share in the absolutist claim that all men were equal as was the case with so many Enlightenment thinkers. But he did value man’s capacity for reason which means that he was certainly a man of his time. According to Malthus, humans stood apart from animals because of their possession of â€Å"reason and will.† â€Å"[Man] is motivated by his physical needs (necessity for food and shelter), ‘the passion between the sexes’ (love, and the ‘desire to possess a beautiful woman’), and the principles of self-love and benevolence† (Simons 1955, 61). It was that latter trait that Malthus most highlighted. Self-interest drives men to seek what they want, to work, and to reproduce. Mixed with the carnal impulses, this presented the very thing which governments must appeal to in order to enact effective social and economic policy. Malthus’ economic philosophy has often been summarized as being inhumane and indifferent to society’s poor. Many during his time believed that the advances being made in the sciences would contribute to a constant betterment of the plight of the poor and thus to the general progress of man. In his famous Essay Malthus said that an increase in food production would lead to a growth of population which would eventually become unsustainable and thus lead to collapse and chaos. â€Å"[M]arshes had been drained by the score in Ireland, with a consequent growth of population and no lessening of the pressure on resources† (Petersen 1979, 473). In order to confront this reality, Malthus proposed

Women Leadership in Africa Essay Example | Topics and Well Written Essays - 250 words

Women Leadership in Africa - Essay Example Competent women leaders are required for good functioning of African governments. For instance, the civil wars that have devastated the continent for decades are based on tribal rivalry. Most leaders in current African governments have been elected into power through such tribal associations. This makes them support ethnic divisions that have continued to trouble the continent. The African continent is also suffering from an unequal distribution of resources. Although the continent is endowed with resources such as oil and other precious minerals, the continent has not fully benefited from this resource. In addition, these resources have become a source of conflicts that have ruined most countries. Conflicts Liberia, Angola, Nigeria, and Congo are related to an availability of resources in these countries. These problems can be solved by increasing the number of female political leaders in African governments. Unlike men, women are against conflicts and they support equitable distribution of a country’s wealth. Thus, women leadership and competence are necessary for a well functioning political system in Africa. Women leaders are also likely to empower women through education and entrepreneurship and this will liberate Africans from poverty.

Shakespeare skilfully weaves political Essay Example for Free

Shakespeare skilfully weaves political Essay Shakespeares aim in Act 1 is to establish Hamlet firmly as the pivotal character in the play What do you see as the importance of Act 1? Shakespeare does use Act 1 to introduce some important political and personal issues and themes to the audience. It is important that these are established in the first act so that the audience are aware not only of the political state of Denmark but also the state of the personal affairs of the main characters of the play. There is a lot of evidence to support this first statement concerning political themes and issues. The state of Denmark is immediately established as an unhealthy political body. This is commented upon by many characters, either directly something is rotten in the state of Denmark or as part of a general feeling of unwell I am sick at heart. This theme of political malaise is also shown through the behaviour of the King and Queen. According to Hamlet, they drink so much that other countries clepe [them] drunkards. Drinking alcohol excessively is unhealthy for the body and as Claudius and Gertrude represent the body politic of Denmark, this shows another sign of malaise and weakness of Denmark politically. The actions of the King and Queen offer another political issue as Claudius is not the rightful king of Denmark. He has usurped the rightful King by murder and has therefore gone against the will of God and only tragedy and ruin can come from the rein of this immoral king. We also learn in this act that Claudius is a hypocrite, Hamlet calls him smiling damned villain, and he proves himself to be an untrustworthy king. This is also shown through the behaviour of the citizens as the audience immediately get a strong sense of mistrust and unease from the first scene as there are cries of Whos there? Nay, answer me. Stand and unfold yourself The presence of a ghost also reflects a sense of unease as Old Hamlet is stuck in purgatory and therefore cannot rest. Not only are political themes addressed in the first act but current political issues are raised as well. Shakespeare uses Claudius speech to update the audience on what is going on in Denmark. We understand there is a threat from Fortinbras who is seeking revenge against Denmark, but whether or not this is a serious threat we cannot tell as the King is not trustworthy. He makes the threat seem small and insignificant but other characters talk of preparation that point towards what would seem to be a war or some form of military action. An imminent war also supports the theme of political unrest and uncertainty. Personal issues and themes are raised as well in the first act. The most intriguing being the issue of Hamlets personal wellbeing. From the beginning he appears to be a very troubled individual, he starts his opening soliloquy with the line o that this too too sallied flesh would melt showing an incline towards suicidal feelings and depression-not without just cause though. He exists within a dysfunctional family unit and has just suffered the loss of his father for whom only he appears to be grieving for. He says in this act I do not set my life at a pins fee showing he has no value upon his own life. This points towards self destructive behaviour and as we learn he must seek to avenge his fathers murder, we wonder to what extremes he will go to. In this act we are also introduced to a lot of different characters and the relationships they have with each other. There is the forbidden, but passionate relationship between Hamlet and Ophelia. As to the nature of the relationship it appears that it is doomed as her brother and her father warn her against it. This could be because they know the intensity of it as her father talks about when the blood burns and blazes. It could be because Hamlet is a unpredictable character a puffed and reckless libertine and heir to the throne, and Ophelia is somewhat nai ve you speak like a green girl and therefore susceptible to him. It raises the issue and theme of love but at the same time tragedy as it appears doomed from the beginning. Another destructive relationship we see in Act 1 is that between Claudius and Gertrude. Together they are a pair of traitors, Hamlet calls Gertrude o most pernicious woman and Claudius is referred to, by Old Hamlet as that incestuous, that adulterous beast. Through their relationship the theme of betrayal is portrayed as they have both betrayed Old Hamlet by murdering him and through damned incest. As a result of this we learn of Hamlets broken relationship with his mother and the forced, false relationship with Claudius which reflects the on-going theme of appearance versus reality. There is also the personal issue of brotherly betrayal and going against nature, as it is described as unnatural, which is reminiscent of the biblical story of Cane and Abel. And also the devoted relationship between Hamlet and his father which is put to the test as Old Hamlet requests that Hamlet avenge his death. At first Hamlet is eager to do this Haste me to knowt that I with wings as swift as meditation or the thoughts of love may sweep to my revenge but later views it as more of a burden The time is out of joint; O cursed spite that ever I was born to set it right but nevertheless feels it is his duty to his father. A similar devotion, tinged with sadness and disappointment is the relationship between Old Hamlet and Gertrude. Although it seems Gertrude has forgotten about Old Hamlet within a month, ere yet the salt of most unrighteous tears had left the flushing in her galled eyes, she married it seems that Old Hamlet still has affections for her. He warns Hamlet taint not thy mind nor let thy soul contrive against thy mother aught showing that he does not wish Hamlet to hurt or alter his attitude towards his mother is his quest for revenge. Yet his disappointment and hurt is clear as he calls her my most seeming-virtuous Queen. In support of the second statement, Shakespeare also uses Act 1 to establish Hamlet firmly as the pivotal character in the play. He is immediately established as the character who has the ability to drive the plot. He is entrusted with a mission from his dead father and the audience are left at the end of Act1, anticipating what he will do. What happens in the rest of the play largely depends on Hamlets actions. He is the only character so far that the ghost talks to, which shows that Hamlet is an important character and a pivot in the play around which the plot and characters revolve. Not only is Hamlet central to the plot of the play, Shakespeare also uses him to characterise many themes and issues as he is an intriguing character with an added depth that other characters do not have, which is created through Shakespeares use of soliloquies. In act1 alone he has two soliloquies, which permit the audience insight into his personality and innermost thoughts. Yet despite this he still unreliable as he proves to be a mentally unstable character and his actions still provoke many questions. Through this, the theme of appearance versus reality and acting are explored through the character of Hamlet. His supposed ill mental health also represents the theme of sickness and disease that has already been established as a main theme, and of course the theme of madness. Hamlet is singled out through the use of visuals as well as he is the only one on stage wearing black while Claudius is giving his uplifting, motivating speech Good Hamlet, cast thy knighted colour off. This is to reflect Hamlet as being alone in his grief and mourning for his father which also raises the issue of family relationships. The fact that he is the true heir to the throne, and the rightful King of Denmark now that his father is dead, also puts Hamlet at the forefront of the play He is automatically in the centre of many themes that surround this issue of betrayal and revenge. Many relationships centre around Hamlet as well, as depicted in the earlier argument, and sub plots arise from this, for example the forbidden love of Hamlet and Ophelia. I think the importance of Act 1 is summarised by both these statements. Political and personal themes and issues are raised and affirmed and so is the character of Hamlet. Shakespeare does this to introduce the tragic tone of the play and introduce important issues and themes. The main plot of revenge is also established in Act 1, as are the sub plots like the relationship between Ophelia and Hamlet and the threat of war or attack from Fortinbras. Characters are established and now that the audience are aware of all this, they are able to follow the action that ensues in the remainder of the play.

Law and Criminality Perspectives

Law and Criminality Perspectives Laws are rules of conduct to guide all people; they are rules that can be enforced by a legitimate authority. More laws are made and enforced as our world and society becomes increasingly complex. Laws are basically rules of basic behavior and order written down by man as an attempt to help us all live together more happily and safely. Whether they are written or not, they are the basis for all societies, because without some form of agreement and co-operation between people, society would not exist. Most laws are for our own benefits and protection; they preserve public order and policy. Without laws, a society will be an anarchy, dysfunctional, full of chaos, injustice and immorality. Without laws, we would all live like animals in nature, each person pursuing ones own desires with no regard for the effects of his or her behavior on others and this would lead to suffering. Laws, in general do not try to limit the freedoms that people consider necessary, but rather to secure these freedoms by prohibiting anyone else from violating or robbing them. Laws prevent people from harming others, and do whatever one feels like to anyone else by setting punishments for those harms if they are committed. Another purpose of laws is to resolve disputes, since laws are consistence rules made to be applied in almost every situation. Though many of us do not need laws to guide us in everything we do, some others need very clear rules and boundaries to live by. Not everyone will agree or like ev ery law given, but rational people understand the need and purpose of laws. A crime is an act against the law and punishable by the law. Certain laws that exist would be considered by most of us as silly or unnecessary. Some of those laws are still enforced and may be even more enforced than other laws, because the government, often times makes a lot of money off of certain laws. There are usually so many laws from a government that if we were to read the whole list, we will probably be surprised at the number of laws we break on a regular basis without even realizing it. Most common examples are speeding, texting or talking while driving, littering, downloading music illegally and others.  [i]  Ignorance is one of the causes for people to break laws; it is however not accepted as an excuse. Desperation is another cause, someone who does not have enough food maybe driven to steal food, so people living in poverty may commit crimes as a way to survive. Many break laws out of greed and selfishness, for example committing fraud, theft or murder to gain what belongs to someone else deceitfully and unfairly. Others break laws out of malice, anger, jealousy or just carelessness. In general, the government of nations create and decide which laws to pass, as making laws to keep order is a part of governing. In the United States, laws are written and made by the Senate and the House of Representatives which make up the Congress.  [ii]  In Australia, laws are made by its parliament even though the country is a constitutional monarchy and has a queen.  [iii]  In Saudi Arabia, as one of the few absolute monarchies that still exist today, the creation and decision about laws are up to the king and his chosen ministers.  [iv]  Aside from laws of independent nations, there is also international law, which are laws guiding individual nations conduct and their relationships with one another, the international organization, the United Nations is responsible for this. The International Bill of Human Rights, which was first drafted as a common standard of achievement for all peoples is widely accepted as the list of rights that should be kept and respected by all states. Almost all countries that exist are members of the United Nations, and are obligated to respect the basic international human rights laws.  [v]  vi The International Court of Justice (based in the Peace Palace, The Hague, Netherlands pictured above) is the principal judicial organ of the United Nations. The ICJ settles legal disputes between states, who must agree to abide by the Courts jurisdiction before their case will be heard.  [viii]   There are different legal systems that are in use throughout the countries in the world, with three main ones. The most common legal system is Civil Law, which is the legal system of France and many nations that were conquered by France, including many countries of Latin America. In the UK, and countries that were colonies of the UK, including India, USA, Australia and many others, have legal systems which are based on Common Law. Common law is determined by judges, it can be applied to many different situations and it is more flexible. The Civil Law system on the other hand, is a collection of laws, they are not decided by judges or open for interpretation. Both systems have advantages and disadvantages. The third most common law system is religious Islamic law, which are enforced in Muslim countries, the Sharia and the Fiqh. This law is believed by Muslims to be directly from God and so cannot be changed by even a government or King.  [ix]   x Problems arise with different law systems in different countries. Examples of this are the cases of two British couples who were arrested and served jail sentences for kissing, and showing intimacy in public in Dubai, United Arab Emirates.  [xi]  According to the legal system of the UAE, what they did was indecent and offending behavior.  [xii]  Disputes arise as these couples were foreign citizens, and in countries where Islamic law is not practiced, it would be considered extreme to arrest or imprison people for kissing or displaying affection in public. Some other controversial issues surrounding different legal systems are: the one-child policy in China  [xiii]  , having a national dress code like that in Saudi Arabia, the capital punishment, executions by beheading, amputation of hands for theft, and others.  [xiv]  Torture, or other cruel punishments like amputation are prohibited by international human rights standards, but the punishments and seriousness of cr imes differ in different legal systems. This makes it difficult to judge a law or case fairly and morally. Practices, laws or policies such as controlling what people wear too strictly, harsh punishments such as death or amputation for crimes like stealing, or limiting the number of children a person may have may be viewed in an international perspective as violating human rights. The line between just and unjust in the legal systems we have today is not clear so such disagreement problems will remain. Local/National Perspectives The National Assembly of Vietnam is responsible for making and passing laws. The legal system practiced in Vietnam is based on communist legal theory and the French civil law system. As a Socialist state, the countrys government has much control over the media and organizations within the country. The Vietnamese government was able to outlaw many religious organizations, touching on the freedom of belief and has been criticize. As the country increasingly involved and joins into many international organizations, it has been more sensitive to human rights abuses due to global criticism. Vietnam is relatively safe with average crime rates. A few of the major crimes include corruption, illegal drug use and digital piracy.  [xvi] Since economic liberalization, corruption has risen sharply in Vietnam. In the Transparency Internationals corruption perception index for 2008, Vietnams corruption rate ranked 121 out of 160. A cause for high corruption rate in Vietnam would be the very low salaries of public officials. In 2006, the minimum salary for state employees is still only 28 dollars per month after it has been raised by nearly 30 percent. It has gotten so bad that after a corruption scandal in 2008, Japan, Vietnams biggest donor in development assistance suspended its aid to Vietnam, saying that Vietnam must take stronger measures in dealing with corruption. Corruption is a threat to investment and aid and it is a big problem on Vietnams road of development. There have been attempts in reducing this problem; an example of this is Vietnam has signed the United Nations Convention Against Corruption, which would criminalize the acts of Vietnamese officials paying bribes abroad or accepting bribes from foreign companies.  [xxiii] According to Business Software Alliance, the largest, and one of the most important of IT groups in the software industry that exist, Vietnam had the worst rate of software piracy in the world. A very large number of all kinds of software, movies and music are pirated, meaning they are illegally duplicated or distributed. In 1998 the digital piracy rate of Vietnam ranked first at 98%, this means that for every 100 copies of software application, 98 are illegal. In 2004, this number was 95%, and it is estimated that for each legitimately bought package of software, 20 illegal copies are made on average. A cause for this is many countries seldom make, let alone enforce laws to protect intellectual property. It is understandable that piracy is thought of as a path to enter the information and technology world with less expense, it actually hurts the countrys own economy. As piracy spreads, software developers are deterred from entering the market. Piracy, and the lack of laws to prevent piracy will not give a decent opportunity for citizens of a country to establish a software industry, preventing the country to become high-tech. In 2010, software piracy rate of Vietnam is 85 per cent. As result of the big efforts of the government and business community to protect copyright, despite still having a very high rate, through the years the percentage has gotten lower and there is no doubt that there has been progress in reducing piracy.  [xxvi] xxx Drug trafficking is present among Vietnams major crimes. It is estimated 200,000 Vietnamese, as young as 15-16 years old use opiate drugs, with 50,000 people using heroin. About 75% of all identified drug users in Vietnam are under 23, according to UNs Drug Control Progamme. Most people with HIV, about two-thirds are drug users, and this virus is spread along with drugs. A cause for this is unemployment in the country; much money is gained just for transporting drugs from one city to another. The lack of money also keeps the government from being able to help drug addicts or do very much. To deal with this major crime, the Vietnamese laws against drug trafficking are some of the harshest and most severe in the world. In 2009 a number of crimes have been removed from the list of crimes punishable by death, including rape and bribery, but not drug trafficking. The possession or smuggling of a certain amount of drug in Vietnam could result in the death penalty.  [xxxi]   Family/Personal Perspectives Most of us would consider ourselves innocent law-abiding citizens, but this is of course ignoring the mostly small crimes we commit regularly if not daily. If even the smallest act of crime was not over-looked, every one of us would be classified as criminals, including my family, friends and myself. Common offenses include stealing office supplies for personal use, littering, talking while driving among many other things. We all at one point or another have excused ourselves by saying certain laws dont apply to us, or since everyone else is doing it, why must I not? This however, doesnt really change the fact that were all quite guilty as law breakers, whether we want to acknowledge it or not. Like with almost every other issue we created in the world, some of their causes are our pride and will to resist or not take seriously the authorities we have above us, whether the authority is good or bad and there is also peoples tendency to ignore, or twist the truth to ones own preference and advantage. In my local community there isnt a high crime rate, or at least it is not very obvious and I feel relatively safe. Like most large, densely populated cities across the world, petty crimes are a typical problem. Although violent or armed crimes occur, they are rare, while little crimes like pick-pocketing, traffic violation and speeding occur regularly. In Vietnamese cities, motorcycles are the most commonly seen type of vehicle, and bag, jewelry or other belongings of people being snatched by motorcyclists are quite common. These types of crimes can result in serious injuries as in the process of purses or bags being snatched, the straps across the victims bodies could drag the victim along the ground by the thiefs motorcycle. There have been incidents involving crime, like mirrors on my family and friends vehicles being stolen often, and risks of frauds but there has not been a case where we are seriously affected. To come up with solutions to criminality, we must look back to its causes. Many break laws out of desperation, greed or lack of knowledge. Law-breaking starts at a young age, and education is a fundamental cure. A person with a better education and qualifications has a more hopeful future, and will less likely be unemployed and driven to criminality to survive. An education with focus on ethics and values should be able to reduce crimes committed out of selfishness and greed. Thus, a key to the criminality problem is giving all people and criminals a fair opportunity to be trained in to responsible citizens.

World Trade Center Attack :: 9/11 september 11 patriotism essays

World Trade Center Attack Reactions to the events of September 11, 2001 run the gamut of human emotion and cognition. There cannot be any doubt of the crime's horrendous nature. Disgust and revulsion might be the best way to describe the sense one feels at the calculated murder of innocent thousands. What more, this was not an attack by another sovereign state. It was an attack by an organization in the shadows. In its aim, no one is sure. What does a terrorist organization gain by committing such acts anyway? In the confiscated tapes depicting Osama bin Laden, the violence surpassed his vision. The expected damage was to be far less worse. But it seemed as if the scale and scope of the onslaught did not faze him in the least bit. The martyrs were going to heaven. And the United States had a lot to say about that. Most denounced the terrorists as cowards, but there were a few, such as Susan Sontag and Bill Maher, who did not feel the same way. There was a sense of overwhelming patriotism, and to say anything otherwise, was foolhardy. And the American flag was everywhere. Even shoes came in the red, white, and blue. Defiling the flag seemed to become downright patriotic. Courage became debatabe, heroism standard. Soon both Sontag and Maher were denounced, even called traitors. What kind of new war was this? Albert Camus states that: By attributing too much importance to admirable actions, one ends up paying indirect homage to evil. For one leads others to assume that such admirable actions are so valuable only because they are rare, and that human activity is far more frequently motivated by nastiness and indifference. (The Plague) These words are full of implication. But to hone in on the media treatment of the events of 9/11 and the war on terrorism in general, one sees the role mass media plays in shaping today's heroism. It is difficult to turn to media and find information without some moral connotation. This after all, is not the proper role of mass media. Or is it? The over-saturation of images and commentary regarding the terrorist actions in the United States is potentially dangerous. This is not to say the issue be taken lightly. That would be delusional. But with recent news of a documentary detailing the events to air on network television, one is left to ponder the merits of this.

Surveillance and the right of privacy Essay -- Research Surveillance P

Surveillance and the Right of Privacy Introduction to Surveillance: According to Merriam-Webster’s collegiate dictionary, surveillance is defined as a â€Å"close kept watch over someone or something (as by a detective).† Surveillance has been used ever since the days of, â€Å"Follow that cab!† From their primitive state, surveillance techniques and technology have evolved. Policing agencies no longer need to use methods of surveillance such as listening through walls, looking through windows and over fences, and even sifting through a suspect’s garbage. Because of the continuous development of new technology, policing agencies can hear, see, and track almost everyone and everything. As more and more technology is developed, who is to regulate the use of the technology and surveillance? Parabolic Microphones and â€Å"Bionic Ears†- This technology allows a person to amplify sounds (i.e. talking, movement) from a long distance away. For example, a suspect’s conversation can be pinpointed and heard 50 meters away as if the sounds were coming from short distance. Digital Audio Equipment- Digital Audio Equipment allows police agencies to listen and record a phone conversation at any given time. These range from a digital voice stick that can be hidden in a room, or a â€Å"bug† device that can be placed inside a phone (landline or cellular). Night Vision- Night Vision Goggles are electronic devices designed for observing remote objects and orientation at night. Special military, security forces, pilots, paratroopers, security agents and tact ops commandos have used this equipment. Covert and Fixed Cameras- The use of covert cameras allows security and policing agencies to hide cameras, in turn, they would ca... ...rveillance will be ethical is if policing agencies are policed. By making sure that these agencies follow strict codes, this will reduce the amount of unethical uses of surveillance technology. Although this would be the most ethical way to handle this issue, I feel that it would be hard to stop all unethical uses of surveillance. The continuous advancements in surveillance technology will continue to make it more difficult to regulate the use of surveillance.

Ipv4 to Ipv6 Transition

I P v 4 TO IP v 6 TRANSITION – UPDATE 2011 An overview of the new Internet a ddressing protocol, its implications for b usiness and government, and Telstra’s a pproach to the transition.

IPv6 is the next-generation Internet protocol that will replace IPv4, providing a vastly expanded address space. This white paper provides an update on the current industry status of IPv6, how the IPv4 to IPv6 transition will affect some organisations, and Telstra’s perspective on the transition. Internet Transition IPv4, the dominant addressing protocol, is rapidly running out of capacity and will be replaced by IPv6The protocol that governs communication on the Internet (and most intranets) today is called Internet Protocol version 4, or IPv4. The popularity of the Internet has caused a shortage of public IPv4 addresses and they are quickly running out, with the glo bal registry of IPv4 addresses from the IANA (Internet Assigned Numbers Authority) exhausted in February 2011 and the Asia-Pacific regional registry in April 2011I. Other Regional Internet Registries (RIRs) are expected to be exhausted between 2012 and 2014II. Once this happens, no more IPv4 addresses will be allocated to Internet service providers (ISPs).Individual ISP run-out will depend upon how well each ISP manages its address pools compared to the rate of each ISP’s subscriber growth. The transition from IPv4 to IPv6 is a popular issue and one which the industry will spend more time managing in the coming years. The transition is complex and will require IPv6 support by an end-to-end industry ecosystem. The ecosystem includes customer premise equipment, modems/home gateways, network systems, management (OSS/BSS, tools), content and applications. Telstra’s Approach Telstra’s approach is based on the dual-stack solution, allowing both IPv4 and IPv6 addresses to co-existTelstra will ensure that customers can migrate to IPv6 at their own pace, with minimal impact to services Telstra has been planning for the IPv6 transition for a number of years. We have a defined transition strategy and a well-advanced IPv6 implementation program. Our strategy for IPv6 introduction is based on the dual-stack solution, allowing both IPv4 and IPv6 addresses to co-exist until the transition to IPv6 is complete. This approach will make sure that the transition occurs with minimal impact to customers. Customers will not be forced to move to IPv6 overnight – they can deploy and migrate to IPv6 as they become ready.Telstra is already testing dual-stack technology on a number of key networks and products to seamlessly introduce IPv6. Similar to service providers, businesses face a challenge in undertaking the complex transition of their IPv4 internal ecosystems without impacting services. Just as Telstra has done, it is advised that every online or IT-ba sed business should prepare an IPv4 to IPv6 transition strategy. Telstra will provide timely information and updates on our own program of work to assist customers, suppliers and others in the industry to manage their transition. 3 WHAT IS IP v 6?IPv6 was designed during the mid-1990s, when the Internet Engineering Task Force (IETF) realised that IPv4 address size constraints would soon be a major impediment to the continued growth of the Internet. IPv6 was first known as the Next Generation Internet Protocol (IPng) during development within the IETF. Since 1998, it has officially been known as IPv6. In the transition to IPv6, both IPv6 and IPv4 will co-exist until IPv6 eventually replaces IPv4. The most obvious difference between IPv6 and IPv4 is the vastly expanded IP address space available The most obvious difference between IPv6 and IPv4 is the address size.IPv6 addresses comprise 128 bits, whereas IPv4 addresses comprise 32 bits. This difference results in a huge expansion in available IP address space: ? I Pv4: 2 32 a ddresses equals 4. 3 billion addresses (less than the global human p opulation of 4. 7 billion) ? I Pv6: 2 128 a ddresses. Because the last 64 bits are used to allocate a ddresses within a subnet, that leaves 2 64, which equals 18 billion billion s ubnet addresses. IPv6 is not backwardly compatible with IPv4 Whilst IPv6 performs the same address function as IPv4, IPv6 is not backwardly compatible with IPv4. Therefore, an IP data session must use either IPv4 or IPv6 end-to-end.IPv6 and IPv4 can be used together with translation mechanisms such as Application Layer Gateways when the applications are known and supported end-to end. 4 IP v 4 ADDRESS RUN OUT The global top-level registration body, IANA (Internet Assigned Numbers Authority), exhausted its supply of available IPv4 addresses in February 2011. APNIC (Asia Pacific Network Information Centre) is the Regional Internet Registry which allocates IP addresses in the Asia-Pacific region. U nfortunately for Australia, APNIC effectively ran out of addresses in April 2011. The Asia-Pacific is also the highest growth region for IP address llocation. Telstra and any other ISP in the Asia-Pacific region are now only eligible for a total allocation of 1024 further addresses from APNIC. There will be no further large allocations of IPv4 addresses for Asia-Pacific ISPs Because no further large allocations of IPv4 addresses are available, the ability of Asia-Pacific ISPs to allocate IPv4 addresses for new customers depends on the number of addresses they already hold, the rate at which they are using them for new services, and the ISP’s capability to adopt address translation technologies, which may reduce their rate of address demand.These factors will be different for each ISP, so it is likely that ISPs across the industry will run out of IPv4 addresses across a wide timeframe – some may run out within only a couple of years, others may be able to delay that exh austion well into the future. 5 WHAT HAPPENS WHEN IP v 4 ADDRESSES RUN OUT? Internal enterprise networks using private IPv4 addresses will not be affected IPv4 and IPv6 will co-exist on the Internet for many years Firstly, internal enterprise networks using private IPv4 addresses will not be impacted.Nor will the run-out impact existing IPv4 networks and IPv4 based services already allocated IPv4 addresses — they will continue to operate normally. Secondly, IPv4 and IPv6 will co-exist in the Internet for many years, quite likely for decades. Unlike Y2K, there is no cut-off date when IPv4 use will cease and the world will fully migrate to IPv6. The plan is for gradual transition: different regions and industry players will move to IPv6 at different rates. Consequently, end users will need the capability to access both IPv4 and IPv6 content and services on the Internet. This dual apability may be inherent in the end users’ equipment, or may be provided transparently by t heir or the content publishers’ ISPs. To enable this dual protocol access during the transition period, technology solutions were developed in conjunction with the development of the IPv6 protocol in the mid-1990s. Three categories of transition technologies exist: ? Tunnelling – encapsulates one protocol within another (e. g. IPv6 in IPv4, IPv4 in IPv6) ? Protocol Translation – translates packets between protocols (e. g. IPv6 to IPv4) ? Dual-stack – support both protocols in parallel within one network. Telstra’s dual-stack path nables both protocols to co-exist on our networks Telstra has chosen the dual-stack path, enabling both protocols on its networks. The use of dual stack will ensure our customers have the current functionality of IPv4 always available to them even while they start deploying IPv6 in their systems. The transition from IPv4 to IPv6 is a known issue which the industry will have to manage over the coming years. The transition w ill take time as it will require IPv6 support by an industry end-to-end eco-system including CPE, modems/home gateways, networks, systems (OSS/BSS, tools), content and applications.Figure 1: IPv6 Ecosystem Systems & tools Carrier/ ISP Client apps Consumer electronics Modems Operating systems Mobile handsets Public IPv6 Content/Apps Global Internet Network vendors Content/Apps Systems & tools Servers IPv6 is the accepted solution, however, moving the entire ecosystem to IPv6 will take many years Source: Telstra 6 WHAT HAPPENS WHEN IP v 4 ADDRESSES RUN OUT? Telstra continually monitors industry developments with regard to the other transition technologies and we may choose to apply other methods where appropriate. Co-existence of IPv4 and IPv6Dual-stack (IPv6/IPv4) remains the accepted industry direction for the introduction of IPv6. Tunnelling has sometimes been used by early IPv6 adopters where native IPv6 has not been available end-to-end. IPv4 to IPv6 protocol translation mechanis ms may also be applied in the future in certain circumstances.

This has led some governments to set IPv6 technology mandates to ensure a well-managed transition from IPv4 to IPv6 prior to the run-out of IPv4 addresses. The smooth and ordered adoption of these technologies will ensure continued Internet connectivity for all of their citizens. Initially targeted at enterprises, institutions and government elated Internet services, IPv6 mandates are now being issued for consumer broadband services The technology mandates have been primarily targeted at enterprises, institutions and departments that provide governments with their Internet connectivity services. Only recently IPv6 mandates for consumer broadband services have been issued. North America In August 2005, the US OMB (Office of Management and Budgets) issued Memorandum M 05 22: Transition Planning for Internet Protocol Version 6 (IPv6). This sets the US Federal Agencies a hard deadline for compliance to IPv6 on their core IP networks.This mandate led many major US Service Providers (e. g. AT&T, Sprint, Verizon, QWest, NTT America) to develop government and enterprise solutions to allow agencies to buy IPv6 products and services to meet their core connectivity requirements. In practice, all of the agencies met the mandate because they were able to demonstrate that their backbone networks were capable of carrying IPv6 packets by the agreed deadline. However, there was no need to actually im plement IPv6-based services. A draft roadmap for IPv6 adoption by the US Government has recently been prepared. EuropeThe European Commission communicated an IPv6 action plan in May 2008. The target was to have 25% of European customers accessing the Internet using IPv6 by 2010, which challenges all players (ISPs, content providers, customer premise equipment vendors, governments and organisations) to work towards this target. Asia Many Asian countries, including China, Japan and Korea have been early adopters of IPv6 due to government mandates. For example: ? C hinese Government Strategy: C hina Next Generation Internet (CNGI) sets o ut a five year plan (2006-2010) for the adoption of IPv6 Korean Government Strategy: T he Korean Government has the strategic IPv6 Promotion Plan II, which sets a vision of deploying IPv6 for the public sector. 8 GOVERNMENT MANDATES Australia The AGIMO (Australian Government Information Management Office) has set the following timeframes for IPv6 adopt ion within the Australian Government and its departments: ? Preparation Jan 2008 – December 2009 ? Transition Jan 2010 – December 2011 ? Implementation Jan 2012 – December 2012. The Australian Department of Defence has also mandated a move to IPv6. 9INDUSTRY READINESS FOR IP v 6 Industry has been slow to adopt IPv6 since few commercial drivers exist Across the globe, the industry has been slow to adopt IPv6, since very few commercial drivers for migration have existed at present. By its very nature, the Internet involves a huge number of disparate groups and thus a coordinated approach is difficult to achieve. The lack of a commercial imperative is due to a ‘chicken and egg’ situation: why support IPv6 in the equipment if there are no IPv6 services, and why create an IPv6 service if nobody can use it?This situation is now changing with the occurrence of the global IPv4 exhaustion. Nevertheless, while many parts of the industry are now supporting IPv 6, others are lagging behind. The following is a brief analysis of the readiness of key industry sectors: Network Equipment Generally, network equipment vendors already provide IPv6 dual-stack support In the main, network equipment vendors already provide IPv6 support (dual-stack) for the core and edge of networks. Key vendors have been hardware and softwareready for several years, with equipment deployed in small-scale trials.Even though IPv6 capability has existed in most network routing equipment for some time, it has often not been enabled for use. Network control path functions like DNS, DHCP and RADIUS, however, are not yet uniformly supported for IPv4/IPv6 dual-stack across all vendors. These remain among the ‘work in progress’ issues for the industry. Internet Infrastructure Global IPv6 interconnectivity is now growing rapidly Global IPv6 Backbones As IPv4 and IPv6 do not interwork, it is essential there is global IPv6 interconnectivity similar to the IPv4 Inter net today. The global network of IPv6 interconnectivity is now growing rapidly.We expect there will be a substantial interconnected Australian IPv6 backbone between many, if not most, ISPs by the end of 2011. Domain Name Servers IPv6 devices will resolve Internet domain names into IP addresses using IPv6 entirely A critical step along the path to IPv6 was implemented on 4 February 2008, when ICANN (Internet Corporation for Assigned Names and Numbers) assigned IPv6 addresses and provided IPv6 connectivity to six of the Internet’s root domain name servers (DNS). Similar enhancements are being made to other top-level DNS (e. g. for . com and . org). The APNIC servers for the . u domain also have IPv6 connectivity. These enhancements to DNS will allow IPv6 devices to resolve Internet domain names into IP addresses entirely using IPv6. Service Providers To connect to the global IPv6 Internet, customers will need to use a service provider that supports IPv6 and provides the require d connectivity through to the global IPv6 backbones. 10 INDUSTRY READINESS FOR IP v 6 Enterprise Virtual Private Networks (VPN) Service providers in the US have begun offering dual-stack VPN services largely to support federal agencies in response to US Government mandates.Telstra’s dualstack IPv6 VPN product capabilities are in an advanced stage of development. Broadband There are still few consumer broadband IPv6 offerings from ISPs, but it is expected there will be an increasing number in the Australian market during 2011-12. Customer Environment In general, few modem gateways and other consumer on-premise equipment currently support IPv6 Consumer Modems and IP Devices In general, very few modem gateways and other CPE appliances in use by consumers currently support IPv6. The main exception includes some high-end PDA mobile phones running Windows Mobile, and some CPE made for specific markets such as Japan.In the vast majority of cases, these IPv4-only devices will not be economically upgradeable to support IPv6. This is because the device is not upgradeable in any way, or because additional resources (e. g. flash memory or RAM) are required to support IPv6. IPv6 capability from many consumer gateway vendors is only starting to be released during 2011. The long lifespan of broadband modem gateways means that many consumers will not have IPv6 connectivity capability for several years unless they opt to replace their modem with a dual-stack capable gateway. Mobile HandsetsDual-stack IPv4/IPV6 capability is expected to become available on selected new mobile handsets during 2011/12. Carriers will need to support IPv6 in their networks for handset use of IPv6 to be possible. Operating Systems Most, if not all, mainstream consumer and business operating systems available now have IPv6/IPv4 dual stack capability. However, legacy systems with either no or limited IPv6 capability (such as Windows XP) are expected to be in widespread use for several years yet . 11 INDUSTRY READINESS FOR IP v 6 Applications and Content ApplicationsMany applications will work when used with IPv6. Others will need to be checked and modified Applications have to be specifically written to take advantage of IPv4/IPv6 dual stack capabilities in the underlying operating system. In many cases, applications will work correctly when used over an IPv6 network. Others will need to be checked and modified to meet the dual-stack requirements and take advantage of IPv4/IPv6 dualstack capabilities built in to most recent underlying operating systems. Applications can be divided into the following major categories: ?S erver applications: Servers typically include web servers, database s ervers and mail servers, but can also include others such as those used for multiplayer online gaming. The applications running on these servers respond to requests from client applications which are carried across I P networks ? C lient applications: End users run client applications whi ch initiate requests to server applications across IP networks (the web browser being the most common example) ? Peer-to-peer applications: In this case the end user application acts as both a c lient and a server and can communicate directly with other users across I P networks.Most applications interface at the IP socket layer and won’t be affected whether the transport is IPv4 or IPv6. However, some applications may have been originally written in a way that ties them to IPv4, and these will have to be modified. Some examples include: ? Use of hard coded IPv4 addresses ? IP address data structures that only cater for IPv4 size addresses ? U ser interfaces that display an IP address, or allow an IP address to be e ntered only in IPv4 format. Many applications, including web browsers, already support dual-stack function. Others are subject to the planned timing of upgrades by the application developer.Ideally, applications should be agnostic to the use of IPv4 or IPv6. An ap plication that supports dual-stack will usually give preference to IPv6 if it is available, otherwise it will fall back to using IPv4. Content Providers Most major Internet content providers have yet to move to a dual-stack architecture Most major Internet content providers are yet to make the move to a dual-stack architecture. Some have established specific IPv6-only versions of their site to enable IPv6 access to users who have IPv6 connectivity, and who deliberately choose to use IPv6 (e. . ipv6. google. com and www. v6. facebook. com). Many Internet content providers are beginning to plan for a dual-stack architecture. This was exhibited when many content providers participated in World IPv6 Day (held on 8 June 2011) to trial IPv6 at a global level. 12 W HAT DOES THE TRANSITION MEAN FOR BUSINESS? Multinational enterprises and those that deal with government departments are most likely to be impacted by government mandates. This will drive the need to support IPv6 (e. g. Australi an Government departments implementing IPv6 in 2012).The IPv4 public address run-out will mostly affect businesses in their external connections Public IPv4 address shortages will have minimal impact on Enterprise VPNs due to the prevailing use of private IPv4 addressing. The IPv4 public address run-out will mostly affect businesses in their external connections to consumers and the broader Internet. Each business needs to consider whether to deliver IPv6 based services to consumers who prefer to use IPv6. Businesses must ensure an IPv6 communication path from the enterprise edge to where IPv6 supported applications are hostedConsumers will move to dual-stack CPE configured with an IPv6 address as well as an IPv4 address (either public or private) in order to access both IPv4 and IPv6 content. Businesses that host applications accessible via the Internet will need to cater for consumers with IPv4 or IPv6 public addresses. Since each protocol needs to work endto-end, for businesses t he transition does not end with deployment of dual-stack devices at the enterprise edge. It also requires enterprise network design changes to make the communication path IPv6-capable from the enterprise edge to where IPv6 supported applications are hosted.Businesses face a similar challenge to service providers, such as Telstra, in making the IP addressing transition. Transitioning to IPv6 requires the full ecosystem to move (i. e. network equipment, modems, consumer devices, operating systems, applications, content servers, IT systems, etc). Therefore, the transition from IPv4 to IPv6 will be a large and complex task that will require significant coordination across the full spectrum of players involved in end-to-end IP services. 13 WHAT IS TELSTRA’S APPROACH TO THE TRANSITION? Telstra has been planning for this transition for a number of years.We have a defined transition strategy and a well-advanced IPv6 implementation program. Telstra has prepared for the transition thro ugh a clear strategy and implementation program Our strategy for IPv6 introduction is based on the dual-stack approach, allowing both IPv4 and IPv6 addresses to co-exist until the transition to IPv6 is complete. This approach will make sure that the transition occurs with minimal impact on customers – they are not forced to move to IPv6 overnight and can deploy and migrate to IPv6 as they become ready.Telstra is already testing a number of key networks and products to seamlessly introduce IPv6 across our services. Timing for implementation in each product will depend on business drivers and equipment availability (e. g. CPE). It covers services across Telstra Internet Direct (TID), Enterprise networks, Consumer Broadband, Mobiles and Telstra’s global networks.

Essentially unlimited Internet addressing ? Leverages the Telstra Next IP ® network. 14 WHAT IS TELSTRA’S APPROACH TO THE TRANSITION? BigPond Broadband Most consumer broadband customers will be more interested in the content and applications they use, rather than which IP addressing protocol is being used. Nevertheless: ? For many, the trans ition to IPv6 will occur smoothly and transparently as e ach of the components of the end-to-end service moves to dual-stack ( e. g. odems, PCs, content) ? T he industry is expecting that Internet content and applications will be d ual-stack or IPv4-only for a long time to come ? I t is unlikely that any significant content on the Internet will be available t hrough IPv6-only for many years yet. Mobiles including Telstra Mobile Broadband ? I nitial availability of IPv6-capable mobile devices is not expected u ntil 2011/12 ? I n the future there may be developments in self-contained mobile solutions, w hich will also drive IPv6 use (e. g. Telemetry and machine-to-machine s olutions).Applications and Content Telstra applications and content will transition to be offered over IPv6 (to achieve end-to-end IPv6) as well as IPv4. Telstra’s Global Networks Telstra’s global networks operated by Telstra International Group adopted the same business approach as Telstra’s g uideline for the IPv4 to IPv6 transition. Key features include: ? D ual-stack approach to seamlessly support the co-existence of IPv4 and I Pv6 IP routing on global IP networks, including the MPLS-VPN platform and G lobal Internet / IP Transit platform N o hard cut-over for customers and continuing support for customer IPv4 a ddress-based IP routing on Telstra global networks in the coming years ? C ontinue IPv4 and IPv6 support for IP network’s auxiliary services such as D NS services on global Internet platform, looking glass on online port etc ? F rom FY 2011/12, Telstra International Group will start leasing IPv6 addresses to customers needing to connect to Telstra’s global IP networks, with limited I Pv4 Address also available ? Native IPv6 Address IP routing on core network is on the road map ?Telstra is committed to work with global network partners for native I Pv6 traffic peering and/or interconnection for both private and public I P networks. 15 WHAT SHOULD B USINESSES DO NOW? Businesses can begin to prepare for their own IP addressing transition through the following steps: 1. Conduct an IPv6 readiness assessment ? Network hardware ? Servers, PCs (e. g. operating systems) ? Network management and security ? Applications ? IT systems ? Organisational capability (IPv6 skills) ? Understand coexistence implications (performance, resources). 2. Prepare an IP addressing strategy Develop a high-level view of transition approach for the business. 3. Develop an end-to-end program view ? Network, IT, devices, applications, etc ? Processes to minimise impacts ? Communication of the IPv6 strategy within the business ? Maintain network security through the transition to IPv6 ? Work with vendors, system integrators and service providers to define d etail and align timings (e. g. link hardware upgrades to lifecycle p rocesses to minimise costs) ? Analyse transition costs and develop a transition budget. 4. Formulate an Implementation Plan ? Identify d ependencies and major milestones Use phased approach based on priorities and timings. 5. Progress Implementation ? Work in close coordination and consultation with network provider ? Telstra commits to providing timely information and updates on its program o f work to assist customers, suppliers and others in the industry to manage t heir transition. 16 WHAT SHOULD BUSINESSES DO NOW?

The transition will take time as it will require IPv6 to be supported by an end-to-end industry ecosystem including CPE, modems/home gateways, networks, systems (OSS/BSS, tools), content and applications. Telstra has been planning for this transition for a number of years. We have a defined transition strategy and a well-advanced IPv6 implementation program.Our strategy for IPv6 introduction is based on the dual-stack approach, allowing both IPv4 and IPv6 addresses to co-exist until the transition to IPv6 is complete.

Class Flow Label Payload Length Nx t Hdr Hop Limit Source Address Destination AddressIPv6 Header Address Ranges Both IPv6 and IPv4 address ranges are often referred to in CIDR (Classless InterDomain Routing) notation, indicating how many of the bits in the range are used to identify the network prefix while the remaining bits identify subnets and hosts. For example, in 62. 0. 0. 0/8 or (62/8), the ‘/8’ indicates that the first 8 bits in the range are used for the common prefix and the remaining 24 bits are used for the host address within that network. 19 APPENDIX 1 – IP ADDRESSING Individual Addresses and Notation Table2 Address FamilyWritten as Example IPv4 Dotted Decimal Notation 144. 135. 19. 10 (four decimal ranges written to represent each byte of address space) IPv6 Hexadecimal notation (eight hexadecimal ranges written to represent two bytes, separated by colons) IPv6 (short-hand) Hexadecimal notation 2001:0db8:85a3:0000:0000: 8a2e:0370:7334 2001:0db8:85a3::8a2e:0370:7334 (eight hexadecima l ranges with zeros removed) Private Addressing In IPv4, four specific address ranges were allocated for use in private networks (e. g. within an enterprise or home). The ranges are: ? 10. 0. 0. /8 — quite often used by large enterprise networks or internally by ISPs ? 172. 16. 0. 0/12 — often used to number enterprise or ISP backbone networks ? 192. 168. 0. 0/16 — often used in small office/home office (SOHO) applications ? 169. 254. 0. 0/24 — used for link-local applications. These private addresses have no meaning on the public Internet. If external connectivity is required by nodes addressed privately, Network Address Translation (NAT) is used to translate the first three of these address ranges into public addresses when accessing the broader Internet.IPv6 also has a range of addresses identified for local use known as the Unique Local Address range FC00::/7 (defined by RFC4193). In IPv4, when an interface is assigned a link-local address, we assume that the device is only connected to a local network. However, the practice of assigning multiple identifiers to interfaces is expected in IPv6 and therefore, all interfaces maintain a link-local address and additional IPv6 addresses. Table 3: Unique Local Address Range 0 78 FC00::/7 1 48 Global ID 64 Site Subnets Interface Identifier With regard to NAT, industry IPv6 addressing practices are still developing.Although there is a hope that significant use of IPv6 to IPv6 network address translation will be avoided, it is not yet clear as to whether enterprises will use public IPv6 space (derived from a registry), provider IPv6 space (granted from an ISP), or a local addressing scheme together with IPv6 NAT. 20 REFERENCES I The remaining allocations by the Asia-Pacific Network Information Centre are now rationed to a maximum of 1024 addresses per member under their latest policies – see â€Å"Policies for IPv4 address space management in the Asia Pacific region†, http:// www. apnic. et/policy/add-manage-policy.
