The Beginning Of What I purpose

[Magdalena Liendo]

The international currency stability that reigned in the immediate post-war period did not last. Turmoil in international currency markets threatened the common price system of the common agricultural policy, a main pillar of what was then the European Economic Community. Later attempts to achieve stable exchange rates were hit by oil crises and other shocks until, in 1979, the European Monetary System (EMS) was launched.

As a reminder of this point, in August 1968, the Soviet Union led an invasion of Czechoslovakia that put an end to a period of political liberalisation in that country known as the Prague Spring. Like a similar invasion of Hungary in 1956 and military repression in Berlin in 1953, Soviet actions demonstrated what became known as the Brezhnev Doctrine: given the choice between short-term control of Eastern European client states and long-run political and economic reform, the Soviet Union would choose to maintain short-term control. The end of this policy would await a Soviet leader willing to choose long-run reform.

This fledgling cooperation was soon put to the test. The collapse of Communism had given way to the rise of nationalism and ethnic violence, particularly in the former Yugoslavia. At first, Allies hesitated to intervene in what was perceived as a Yugoslav civil war. Later the conflict came to be seen as a war of aggression and ethnic cleansing, and the Alliance decided to act. Initially, NATO offered its full support to United Nations efforts to end war crimes, including direct military action in the form of a naval embargo. Soon the enforcement of a no-fly zone led to airstrikes against heavy weapons violating UN resolutions. Finally, the Alliance carried out a nine-day air campaign in September 1995 that played a major role in ending the conflict. In December of that year, NATO deployed a UN-mandated, multinational force of 60 000 soldiers to help implement the Dayton Peace Agreement and to create the conditions for a self-sustaining peace. In 2004, NATO handed over this role to the European Union.

In an open-architecture network, the individual networks may be separately designed and developed and each may have its own unique interface which it may offer to users and/or other providers. including other Internet providers. Each network can be designed in accordance with the specific environment and user requirements of that network. There are generally no constraints on the types of network that can be included or on their geographic scope, although certain pragmatic considerations will dictate what makes sense to offer.

This was the beginning of long term experimentation and development to evolve and mature the Internet concepts and technology. Beginning with the first three networks (ARPANET, Packet Radio, and Packet Satellite) and their initial research communities, the experimental environment has grown to incorporate essentially every form of network and a very broad-based research and development community. [REK78] With each expansion has come new challenges.



Thus, by 1985, Internet was already well established as a technology supporting a broad community of researchers and developers, and was beginning to be used by other communities for daily computer communications. Electronic mail was being used broadly across several communities, often with different systems, but interconnection between different mail systems was demonstrating the utility of broad based electronic communications between people.

The beginnings of the ARPANET and the Internet in the university research community promoted the academic tradition of open publication of ideas and results. However, the normal cycle of traditional academic publication was too formal and too slow for the dynamic exchange of ideas essential to creating networks.

The Internet is as much a collection of communities as a collection of technologies, and its success is largely attributable to both satisfying basic community needs as well as utilizing the community in an effective way to push the infrastructure forward. This community spirit has a long history beginning with the early ARPANET. The early ARPANET researchers worked as a close-knit community to accomplish the initial demonstrations of packet switching technology described earlier. Likewise, the Packet Satellite, Packet Radio and several other DARPA computer science research programs were multi-contractor collaborative activities that heavily used whatever available mechanisms there were to coordinate their efforts, starting with electronic mail and adding file sharing, remote access, and eventually World Wide Web capabilities. Each of these programs formed a working group, starting with the ARPANET Network Working Group. Because of the unique role that ARPANET played as an infrastructure supporting the various research programs, as the Internet started to evolve, the Network Working Group evolved into Internet Working Group.

This growth was complemented by a major expansion in the community. No longer was DARPA the only major player in the funding of the Internet. In addition to NSFNet and the various US and international government-funded activities, interest in the commercial sector was beginning to grow. Also in 1985, both Kahn and Leiner left DARPA and there was a significant decrease in Internet activity at DARPA. As a result, the IAB was left without a primary sponsor and increasingly assumed the mantle of leadership.

In 1985, recognizing this lack of information availability and appropriate training, Dan Lynch in cooperation with the IAB arranged to hold a three day workshop for ALL vendors to come learn about how TCP/IP worked and what it still could not do well. The speakers came mostly from the DARPA research community who had both developed these protocols and used them in day-to-day work. About 250 vendor personnel came to listen to 50 inventors and experimenters. The results were surprises on both sides: the vendors were amazed to find that the inventors were so open about the way things worked (and what still did not work) and the inventors were pleased to listen to new problems they had not considered, but were being discovered by the vendors in the field. Thus a two-way discussion was formed that has lasted for over a decade.

Network management provides an example of the interplay between the research and commercial communities. In the beginning of the Internet, the emphasis was on defining and implementing protocols that achieved interoperation.

As the network grew larger, it became clear that the sometime ad hoc procedures used to manage the network would not scale. Manual configuration of tables was replaced by distributed automated algorithms, and better tools were devised to isolate faults. In 1987 it became clear that a protocol was needed that would permit the elements of the network, such as the routers, to be remotely managed in a uniform way. Several protocols for this purpose were proposed, including Simple Network Management Protocol or SNMP (designed, as its name would suggest, for simplicity, and derived from an earlier proposal called SGMP) , HEMS (a more complex design from the research community) and CMIP (from the OSI community). A series of meeting led to the decisions that HEMS would be withdrawn as a candidate for standardization, in order to help resolve the contention, but that work on both SNMP and CMIP would go forward, with the idea that the SNMP could be a more near-term solution and CMIP a longer-term approach. The market could choose the one it found more suitable. SNMP is now used almost universally for network-based management.

This discretionary grant program is designed to increase the number of low-income students who are prepared to enter and succeed in postsecondary education. GEAR UP provides six-year or seven years grants to states and partnerships to provide services at high-poverty middle and high schools. GEAR UP grantees serve an entire cohort of students beginning no later than the seventh grade and follow the cohort through high school. GEAR UP funds are also used to provide college scholarships to low-income students.

In 1946, Tokyo Tsushin Kogyo K.K. (Tokyo Telecommunications Engineering Corporation, The predecessor of Sony Group Corporation) started as a small company with capital of just 190,000 yen and approximately 20 employees.
Founder Masaru Ibuka said the purpose of setting up the company was to "establish an ideal factory that stresses a spirit of freedom and open mindedness that will, through technology, contribute to Japanese culture."
Symbolizing Sony's spirit of challenge to "do what has never been done before," the company has continued to release countless "Japan's first" and "world's first" products.
