Hi, The early development of tcp/ip began in 1973, and the cutover from the ARPANET protocol NCP to the Internet protocol TCP/IP was in January 1983. Thus the coming new year 2003 marks the 30th anniversary of the beginnings of tcp/ip and the 20th anniversary of the cutover to tcp/ip from NCP on the ARPANET and the split between ARPANET and MILNET in 1983. Indeed 2003 is a time to celebrate as an important anniversary of the birth of the internet. Ronda ronda@panix.com P.S. A while ago I wrote a paper about the tcp/ip digest which documents the period of the cutover from NCP to tcp/ip. That paper is online at http://www.ais.org/~ronda/new.papers/tcpdraft.txt I also have a paper about the early development of tcp/ip that is online at http://www.columbia.edu/~rh120/other/birth_internet.txt
