ABSTRACT

Vinton Cerf is one of the inventors of TCP/ IP (transmission control protocol/ Internet protocol) around 1978, which was based on his Ph.D. advisor Leonard Kleinrock’s packetswitching theory published in 1961. TCP/ IP became the required protocol of ARPANET (Advanced Research Projects Agency Network) in 1983. It also allowed ARPANET to expand into the Internet, facilitating features like remote login via Telnet, and later, the World Wide Web. During his tenure from 1976 to 1982 as project manager and principle scientist at DARPA (Defense Advanced Research Projects Agency), Cerf was at the center of the global network’s transformation and played a key role in leading the development of the TCP/ IP protocols and the Internet. Cerf is credited as father of the Internet.
