Robert Kahn obtained a Ph.D. degree from Princeton University in 1964, worked for a while at AT&T Bell Laboratories, and then became an Assistant Professor of Electrical Engineering at MIT. He later went to work at Bolt Beranek and Newman, and helped build the Interface Message Processor. In 1972, Kahn was hired by Lawrence Roberts at the IPTO to work on networking technologies, and in October he gave a demonstration of an ARPANET network connecting 40 different computers at the International Computer Communication Conference, making the network widely known for the first time to people from around the world. Kahn then began work on development of a standard open-architecture network model, where any computer could communicate with any other, independent of individual hardware and software configuration. He set four goals for the TCP design: Network Connectivity. Any network could connect to another network through a gateway. Distribution. There would be no central network administration or control. Error Recovery. Lost packets would be retransmitted. Black Box Design. No internal changes would have to be made to a computer to connect it to the network. In the spring of 1973, Vinton Cerf joined Kahn on the project. They started by conducting research on reliable data communications across packet radio networks, and then studied the Networking Control Protocol, building on it to create the Transmission Control Protocol (TCP). TCP had powerful error and retransmission capabilities, and provided extremely reliable communications. It was subsequently layered into two protocols, TCP/IP, where TCP handles high level services like retransmission of lost packets, and IP handles packet addressing and transmission.
