Robert Elliot Kahn (born December 23, 1938) is an American
In 2004, Kahn won the Turing Award with Vint Cerf for their work on TCP/IP.[1]
Background information
Kahn was born in New York to parents Beatrice Pauline (née Tashker) and Lawrence Kahn in an
After thirteen years with DARPA, Kahn left to found the Corporation for National Research Initiatives (CNRI) in 1986, and as of 2022[update] remains its chairman, CEO and president.[11]
The Internet
While working on the
- Small sub-sections of the whole network would be able to talk to each other through a specialized computer that only forwarded packets (first called a gateway, and now called a router).
- No portion of the network would be the single point of failure, or would be able to control the whole network.
- Each piece of information sent through the network would be given a sequence number, to ensure that they were dealt with in the right order at the destination computer, and to detect the loss of any of them.
- A computer which sent information to another computer would know that it was successfully received when the destination computer sent back a special packet, called an acknowledgement (ACK), for that particular piece of information.
- If information sent from one computer to another was lost, the information would be retransmitted, after the loss was detected by a timeout, which would recognize that the expected acknowledgement had not been received.
- Each piece of information sent through the network would be accompanied by a checksum, calculated by the original sender, and checked by the ultimate receiver, to ensure that it was not damaged in any way en route.
Vint Cerf joined him on the project in the spring of 1973, and together they completed an early version of TCP. Later, the protocol was separated into two separate layers: host-to-host communication would be handled by TCP, with Internet Protocol (IP) handling internetwork communication.[12] The two together are usually referred to as TCP/IP, and form part of the basis for the modern Internet.
In 1992 he co-founded with Vint Cerf the Internet Society, to provide leadership in Internet related standards, education, and policy.

Kahn, Bolt Beranek and Newman (BBN), Kahn discusses his involvement as the ARPANETproposal was being written, his decision to become active in its implementation, and his role in the public demonstration of the ARPANET. The interview continues into Kahn's involvement with networking when he moves to IPTO in 1972, where he was responsible for the administrative and technical evolution of the ARPANET, including programs in packet radio, the development of a new network protocol (TCP/IP), and the switch to TCP/IP to connect multiple networks.
