The i-Technology World Celebrates 25th Anniversary of TCP/IP

TCP/IP was adopted by ARPANET on January 1, 1983

Jan. 3, 2008 07:30 AM

Google's new-year logo, which went live as 2008 began, celebrates the 25th anniversary of TCP/IP - adopted by Arpanet on January 1st, 1983. While 'invisible' to most users, many of the layers built on top of TCP/IP are well-known even to laymen: HTTP (Hyper Text Transfer Protocol), FTP (the File Transfer Protocol), SMTP and POP3, and IRC.

The US Department of Defense made TCP/IP the standard for all military computer networking already in March 1982, according to Wikipedia, which continues:

"In the spring of 1973, Vinton Cerf, the developer of the existing ARPANET Network Control Program (NCP) protocol, joined [Robert E.] Kahn to work on open-architecture interconnection models with the goal of designing the next protocol for the ARPANET."

Cerf now works for - who else? - Google.

In a communication today with Open Web Developer's Journal Cerf writes, with characteristic modesty:

"Stephen D Crocker ("Steve") was the leader of the Network Working Group that developed the Network Control Protocol (NCP). I was part of that team but Steve deserves the credit for leading it. It was experience with the NCP on the ARPANET and the differences between ARPANET and the less reliable Packet Radio and Packet Satellite networks that led Bob Kahn and me to conclude that we needed additional functionality at the TCP layer.

On the third iteration of the TCP design, Danny Cohen, Jon Postel and David Reed argued successfully to split IP from TCP so as to support unsequenced, real-time delivery. This led to UDP and the notions of streaming audio and video and other real-time streams."
