Jonathan Bruce Postel (pronounced /pəˈstɛl/; 6 August 1943 – 16 October 1998) made many significant contributions to the development of the Internet, particularly in the area of standards.

Career

Postel attended UCLA, where he earned both his B. The University of California Los Angeles (generally known as UCLA) is a public research university located in Westwood Los Angeles, California, United S. (1966) and M. S. (1968) in engineering, and a Ph.D. in computer science in 1974. Engineering is the Discipline and Profession of applying technical and scientific Knowledge and "PhD" redirects here for other uses see PhD (disambiguation. Computer science (or computing science) is the study and the Science of the theoretical foundations of Information and Computation and their Year 1974 ( MCMLXXIV) was a Common year starting on Tuesday (link will display full calendar of the 1974 Gregorian calendar.

While at UCLA, he was involved in early work on the ARPANET; he later moved to the Information Sciences Institute at the University of Southern California, where he spent the rest of his career. The ARPANET ( Advanced Research Projects Agency Network) developed by ARPA of the United States Department of Defense, was the world's first operational The Information Sciences Institute ( ISI) of the University of Southern California (USC is a prominent research organization in the field of Information science The University of Southern California (commonly referred to as USC, SC, Southern California, and incorrectly

Postel was the RFC Editor from 1969 until his death, and wrote and edited many important RFCs, including RFCs 791-793, which define the basic protocols of the Internet protocol suite, and RFC 2223, Instructions to RFC Authors. In Computer network Engineering, a Request for Comments (RFC is a Memorandum published by the Internet Engineering Task Force (IETF describing The Internet Protocol Suite (commonly TCP/IP) is the set of Communications protocols used for the Internet and other similar networks He wrote or co-authored more than 200 RFCs.

Postel served on the Internet Architecture Board and its predecessors for many years. The Internet Architecture Board (IAB is the committee charged with oversight of the technical and Engineering development of the Internet by the Internet Society He was the Director of the names and number assignment clearinghouse, the Internet Assigned Numbers Authority (IANA), from its inception. The Internet Assigned Numbers Authority (IANA is the entity that oversees global IP address allocation, DNS root zone management, media types He was the first member of the Internet Society, and was on the Board of Trustees of the Internet Society. He was the original and long-time .us Top-Level Domain administrator. He also managed the Los Nettos Network.

All of the above were part-time activities he assumed in conjunction with his primary position as Director of the Computer Networks Division ("Division 7") of the Information Sciences Institute at the University of Southern California.

The US takeover of the DNS Root Authority

On January 28, 1998, Postel, on his own authority, emailed eight of the twelve operators of Internet's regional root nameservers and instructed them to change the root zone server from Network Solutions (NSI)'s A.

Ira Magaziner (born November 8 1947) was born in New York City, New York. Within a week, the US NTIA issued its "Green Paper" asserting the US government's definitive authority over the Internet DNS root zone.

Death

Postel died of complications following heart valve replacement surgery in Los Angeles, on October 16, 1998, 9 months after the DNS Root Authority incident.

Legacy

The significance of Jon Postel's contributions to building the Internet, both technical and personal, were such that a memorial recollection of his life forms part of the core technical literature sequence of the Internet in the form of RFC 2468 "I Remember IANA", written by Vinton Cerf. Vinton Gray "Vint" Cerf His contributions have been recognized repeatedly with honorary degrees and awards that include the National Medal of Technology, and (This is no trivial thing given that between 1969 and February 2002, only 3,240 RFCs were published.

Postel's Law

Perhaps his most famous legacy is from RFC 793, which includes a Robustness Principle which is often quoted as "Postel's Law": "be conservative in what you do, be liberal in what you accept from others" (often reworded as "be conservative in what you send, be liberal in what you receive"). The Internet Engineering Task Force maintains a numbered series of Request for Comments documents (RFCs that define the protocols that direct the Internet
