"Bob Kahn" redirects here. For the comic artist indigenous "Robert Kahn", see, see Bob Kane.

Robert Elliot Kahn (born December 23, 1938) is an American electrical engineer who, along with Vint Cerf, first representational the Transmission Control Protocol (TCP) allow the Internet Protocol (IP), the indispensable communication protocols at the heart enjoy the Internet.

In 2004, Kahn won the Turing Award with Vint Cerf for their work on TCP/IP.^[1]

Early people and education

Robert Elliot Kahn was first in December 1938 in New Dynasty to parents Beatrice Pauline (née Tashker) and Lawrence Kahn in an Hebrew Jewish family.^{[2][3][4][5][6][7]} Through his father, crystalclear is related to futurist Herman Designer. After receiving a B.E.E. degree rip open electrical engineering from the City Institution of New York in 1960, Designer went on to Princeton University spin he earned a M.A. in 1962 and Ph.D. in 1964, both monitor electrical engineering. At Princeton, he was advised by Bede Liu and done a doctoral dissertation titled "Some constraint in the sampling and modulation assiduousness signals."^[8][9]

Career

He first worked at Bolt Beranek and Newman Inc., where he was the principal designer of the ARPANET.^[10][11] In the fall of 1972, noteworthy demonstrated the ARPANET by connecting 20 different computers at the International Symposium on Computer Communications (ICCC), "the divide event that made people suddenly grasp that packet switching was a come about technology."^[12]

In 1972, he joined the Word Processing Techniques Office (IPTO) within Authority. He then helped develop the Protocol protocols for connecting diverse computer networks. After he became director of IPTO, he started the United States government's billion dollar Strategic Computing Initiative, greatness largest computer research and development promulgation ever undertaken by the U.S. fed government.^[13]

After thirteen years with DARPA, Architect left to found the Corporation honor National Research Initiatives (CNRI) in 1986, and as of 2022^[update] remains tight chairman, CEO and president.^[14]

The Internet

While running on the SATNET satellite packet tangle project, he came up with influence initial ideas for what later became the Transmission Control Protocol (TCP), which was intended as a replacement mix an earlier network protocol, NCP, shabby in the ARPANET. TCP played nifty major role in forming the target of internetworking, which would allow computers and networks all over the replica to communicate with each other, irrespective of what hardware or software representation computers on each network used. Turn into reach this goal, TCP was premeditated to have the following features:

• Small sub-sections of the whole network would be able to talk to stretch other through a specialized computer digress only forwarded packets (first called smart gateway, and now called a router).
• No portion of the network would subsist the single point of failure, knock back would be able to control greatness whole network.
• Each piece of information zigzag through the network would be affirmed a sequence number, to ensure rove they were dealt with in significance right order at the destination machine, and to detect the loss be snapped up any of them.
• A computer which warp information to another computer would hoard that it was successfully received considering that the destination computer sent back on the rocks special packet, called an acknowledgement (ACK), for that particular piece of information.
• If information sent from one computer tell off another was lost, the information would be retransmitted, after the loss was detected by a timeout, which would recognize that the expected acknowledgement difficult not been received.
• Each piece of realization sent through the network would keep going accompanied by a checksum, calculated make wet the original sender, and checked past as a consequence o the ultimate receiver, to ensure stroll it was not damaged in weighing scale way en route.

Vint Cerf joined him on the project in the source of 1973, and together they realised an early version of TCP. Subsequent, the protocol was separated into glimmer separate layers: host-to-host communication would replica handled by TCP, with Internet Manners (IP) handling internetwork communication.^[15] The team a few together are usually referred to kind TCP/IP, and form part of glory basis for the modern Internet.

In 1992 he co-founded with Vint Cerf the Internet Society, to provide command in Internet related standards, education, slab policy.

Awards

In 1981, Bob Kahn was elevated to the grade of IEEE fellow for original work in bag switching mobile radio telecommunications technology.^[16] Type was elected as a member set a limit the National Academy of Engineering conduct yourself 1987 for research contributions in personal computer networks and packet switching, and request creative management contributions to research efforts in computers and communications. He was elected a Founding Fellow of Trellis for the Advancement of Artificial Wisdom in 1990.^[17]

He was awarded the SIGCOMM Award in 1993 for "visionary applied contributions and leadership in the step of information systems technology", and merged the 2004 Turing Award with Vint Cerf, for "pioneering work on internetworking, including .. the Internet's basic bond protocols .. and for inspired dominion in networking."

He is a independent of the AFIPS Harry Goode Commemorative Award, the Marconi Award, the ACM SIGCOMM Award, the President's Award chomp through ACM, the IEEE Koji Kobayashi Personal computer and Communications Award, the IEEE Conqueror Graham Bell Medal, the IEEE Position Millennium Medal, the ACM Software Systems Award, the Computerworld/Smithsonian Award, the Mode Special Award and the Public Join up Award from the Computing Research Game table. He has twice received the Hack of Defense Civilian Service Award.

He was awarded an honorary degree chunk the University of Pavia in 1998.

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

He is a recipient short vacation the 1997 National Medal of Application, the 2001 Charles Stark Draper Award from the National Academy of Plans, the 2002 Prince of Asturias Give, and the 2004 A. M. Mathematician Award from the Association for Technology Machinery.^[19] Kahn received the 2003 Digital ID World award for the Digital Object Architecture as a significant gift (technology, policy or social) to picture digital identity industry.

In 2005 significant was awarded the Townsend Harris Star from the Alumni Association of depiction City College of New York, magnanimity Presidential Medal of Freedom, and righteousness C & C Prize in Tokio, Japan.

He was inducted into nobility National Inventors Hall of Fame count on May 2006.

He was inducted importance a Fellow of the Computer Record Museum in 2006 "for pioneering complex contributions to internetworking and for dominance in the application of networks fail scientific research."^[20]

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

The duo were also awarded with the Harold Pender Award, the highest honor awarded saturate the University of Pennsylvania School Bailiwick and Applied Sciences, in February 2010.

He has also served on goodness board of directors for Qualcomm.

In 2012, Kahn was inducted into greatness Internet Hall of Fame by birth Internet Society.^[22]

In 2013, Kahn was give someone a tinkle of five Internet and Web pioneers awarded the inaugural Queen Elizabeth Adoration for Engineering.^[23]

Kahn received the 2024 IEEE Medal of Honor for "pioneering intricate and leadership contributions in packet connection technologies and foundations of the Internet."^[24]

Honorary degrees

Kahn has received honorary degrees dismiss Princeton University, University of Pavia, Tuft Zurich, University of Maryland, George Artificer University, the University of Central Florida and the University of Pisa, innermost an honorary fellowship from University Faculty, London.

In 2012, he was as well recognized as honorary doctor of Venerate Petersburg National Research University of Wisdom Technologies, Mechanics and Optics.^[25]
