The invention of the telegraph, telephone, radio, and computer set the stage for this unprecedented integration of capabilities. The Internet is at once a world-wide broadcasting capability, a mechanism for information distribution, and a medium for collaboration and interaction between individuals and their computers without regard for geographic location. The Internet represents one of the most successful examples of the benefits of sustained investment and commitment to research and development of information infrastructure. Beginning with the early research in packet switching, the government, industry and academia have been partners in evolving and deploying this exciting new technology. Over its fifteen year history, the Internet has functioned as a collaboration among cooperating parties. Certain key functions have been critical for its operation, not the least of which is the specification of the protocols by which the components of the system operate. To get to the origins of the Internet, we have to go back in time to 1957. You probably have no cause to remember, but it was International Geophysical Year, a year dedicated to gathering information about the upper atmosphere during a period of intense solar activity. Eisenhower announced in 1955 that, as part of the activities, the USA hoped to launch a small Earth orbiting satellite. Then Kremlin announced that it hoped to do likewise. Planning in America was focussed on a sophisticated three stage rocket, but in Russia they took a more direct approach, on 4 October 1957 the USSR launched (a 70 kgs bleeping sphere the size of a medicine ball) into Earth orbit. The effect in the United States was electrifying, since it seemed overnight to wipe out the feeling on invulnerability the country had enjoyed since the explosion of the first nuclear bomb thirteen years before. One of the immediate reactions was the creation of the Advanced Research Projects Agency within the Ministry of De fense. Its mission was to apply state-of-the-art technology to US defense and to avoid being surprised (again!) by technological advances of the enemy. It was also given interim control of the US satellite program until the creation of NASA in October 1958. ARPA became the technological think-tank of the American defense effort, employing directly a couple of hundred top scientists and with a budget sufficient for sub-contracting research to other top American institutions.
