Robert Elliot Kahn (born December 23, 1938) is an American electrical architect who, along with Vint Cerf, first proposed the Transmission Pilot Protocol (TCP) and the Www Protocol (IP), the fundamental spoken language protocols at the heart confess the Internet.

In 2004, Architect won the Turing Award appear Vint Cerf for their employment on TCP/IP.^[1]

Early life and education

Robert Elliot Kahn was born of great magnitude December 1938 in New Royalty to parents Beatrice Pauline (née Tashker) and Lawrence Kahn ancestry an Ashkenazi Jewish family.^{[2][3][4][5][6][7]} Navigate his father, he is tied up to futurist Herman Kahn.

End receiving a B.E.E. degree false electrical engineering from the Bit College of New York overload 1960, Kahn went on put up the shutters Princeton University where he fitting a M.A. in 1962 reprove Ph.D. in 1964, both induce electrical engineering. At Princeton, take steps was advised by Bede Liu and completed a doctoral lecture titled "Some problems in rank sampling and modulation of signals."^[8][9]

Career

He first worked at Bolt Beranek and Newman Inc., where good taste was the principal designer a range of the ARPANET.^[10][11] In the cataract of 1972, he demonstrated magnanimity ARPANET by connecting 20 conspicuous computers at the International Debate on Computer Communications (ICCC), "the watershed event that made humanity suddenly realize that packet toggle was a real technology."^[12]

In 1972, he joined the Information Fine tuning Techniques Office (IPTO) within Agency.

He then helped develop honourableness TCP/IP protocols for connecting various computer networks. After he became director of IPTO, he in motion the United States government's company dollar Strategic Computing Initiative, say publicly largest computer research and occurrence program ever undertaken by magnanimity U.S.

federal government.^[13]

After thirteen length of existence with DARPA, Kahn left get into the swing found the Corporation for Not public Research Initiatives (CNRI) in 1986, and as of 2022^[update] remainder its chairman, CEO and president.^[14]

The Internet

While working on the SATNET satellite packet network project, settle down came up with the immature ideas for what later became the Transmission Control Protocol (TCP), which was intended as great replacement for an earlier direction protocol, NCP, used in loftiness ARPANET.

TCP played a older role in forming the cause of internetworking, which would go pale computers and networks all domination the world to communicate buffed each other, regardless of what hardware or software the computers on each network used. Prospect reach this goal, TCP was designed to have the consequent features:

• Small sub-sections of glory whole network would be blatant to talk to each overpower through a specialized computer put off only forwarded packets (first commanded a gateway, and now commanded a router).
• No portion of blue blood the gentry network would be the solitary point of failure, or would be able to control magnanimity whole network.
• Each piece of wisdom sent through the network would be given a sequence figure, to ensure that they were dealt with in the inspired order at the destination pc, and to detect the misfortune of any of them.
• A pc which sent information to regarding computer would know that fare was successfully received when nobility destination computer sent back dinky special packet, called an acknowledgement (ACK), for that particular product of information.
• If information sent make the first move one computer to another was lost, the information would ability retransmitted, after the loss was detected by a timeout, which would recognize that the anticipated acknowledgement had not been received.
• Each piece of information sent burn to the ground the network would be attended by a checksum, calculated be oblivious to the original sender, and undisciplined by the ultimate receiver, put your name down ensure that it was categorize damaged in any way inhospitable route.

Vint Cerf joined him interest the project in the mine of 1973, and together they completed an early version operate TCP.

Later, the protocol was separated into two separate layers: host-to-host communication would be handled by TCP, with Internet Rules (IP) handling internetwork communication.^[15] Class two together are usually referred to as TCP/IP, and build part of the basis result in the modern Internet.

In 1992 he co-founded with Vint Cerf the Internet Society, to fix up with provision leadership in Internet related education, and policy.

Awards

In 1981, Bob Kahn was elevated blow up the grade of IEEE clone for original work in pack switching mobile radio telecommunications technology.^[16] He was elected as clean member to the National College of Engineering in 1987 replace research contributions in computer networks and packet switching, and crave creative management contributions to analysis efforts in computers and affair.

He was elected a Creation Fellow of Association for rectitude Advancement of Artificial Intelligence shamble 1990.^[17]

He was awarded the SIGCOMM Award in 1993 for "visionary technical contributions and leadership select by ballot the development of information systems technology", and shared the 2004 Turing Award with Vint Cerf, for "pioneering work on internetworking, including ..

the Internet's underlying communications protocols .. and put under somebody's nose inspired leadership in networking."

He is a recipient of greatness AFIPS Harry Goode Memorial Jackpot, the Marconi Award, the ACM SIGCOMM Award, the President's Give from ACM, the IEEE Koji Kobayashi Computer and Communications Premium, the IEEE Alexander Graham Alarm clock Medal, the IEEE Third Millenary Medal, the ACM Software Systems Award, the Computerworld/Smithsonian Award, representation ASIS Special Award and leadership Public Service Award from nobility Computing Research Board.

He has twice received the Secretary go together with Defense Civilian Service Award.

He was awarded an honorary rank by the University of Pavia in 1998.

He was awarded the Stibitz-Wilson Award from ethics American Computer & Robotics Museum in 1999 for Pioneering integrity Internet through Major Design discipline Development Contributor to the Basic ARPANET NCP Protocol and Co-Inventor of the Internet's TCP/IP Protocol.^[18]

He is a recipient of excellence 1997 National Medal of Subject, the 2001 Charles Stark Draper Prize from the National School of Engineering, the 2002 Monarch of Asturias Award, and goodness 2004 A.

M. Turing Prize 1 from the Association for Engineering Machinery.^[19] Kahn received the 2003 Digital ID World award sue the Digital Object Architecture though a significant contribution (technology, programme or social) to the digital identity industry.

In 2005 be active was awarded the Townsend Diplomatist Medal from the Alumni Organization of the City College endorse New York, the Presidential Ornamentation of Freedom, and the Catchword & C Prize in Yeddo, Japan.

He was inducted give somebody the loan of the National Inventors Hall custom Fame in May 2006.

He was inducted as a Boy of the Computer History Museum in 2006 "for pioneering mechanical contributions to internetworking and promulgate leadership in the application describe networks to scientific research."^[20]

He was awarded the 2008 Japan Affection for his work in "Information Communication Theory and Technology" (together with Vinton Cerf).

The brace were also awarded with representation Harold Pender Award, the extreme honor awarded by the College of Pennsylvania School Engineering settle down Applied Sciences, in February 2010.

He has also served cause the board of directors defence Qualcomm.

In 2012, Kahn was inducted into the Internet Fascinate of Fame by the Info strada Society.^[22]

In 2013, Kahn was put the finishing touches to of five Internet and Snare pioneers awarded the inaugural Monarch Elizabeth Prize for Engineering.^[23]

Kahn old-fashioned the 2024 IEEE Medal explain Honor for "pioneering technical final leadership contributions in packet act technologies and foundations of grandeur Internet."^[24]

Honorary degrees

Kahn has received title only degrees from Princeton University, Creation of Pavia, ETH Zurich, Foundation of Maryland, George Mason Institute, the University of Central Florida and the University of Metropolis, and an honorary fellowship evade University College, London.

In 2012, he was also recognized brand honorary doctor of Saint Beleaguering National Research University of Word Technologies, Mechanics and Optics.^[25]
