The 10/29/1969 was a two node test of the Arpanet and involved connecting a
terminal at UCLA to a host at SRI International that were connected via two
Interface Message Processors (IMPs) which we would call packet switches
today. There was no host level protocol for that test. The protocol that
linked the Arpanet hosts was developed under the leadership of Steve
Crocker and was eventually called either the host-to-host protocol or
Network Control Protocol (or Program) in 1970 (see IETF RFC document
series, also started by Steve Crocker; RFC 33 Feb 1970). Three of us worked
at the Network Measurement Lab, led by Leonard Kleinrock: Steve Crocker,
Vint Cerf and Jon Postel, among others. The Internet development started in
the Spring of 1973 at Stanford and was initiated by Bob Kahn (then at
DARPA) who invited Vint Cerf to work with him on the project. The
Transmission Control Protocol (TCP) protocol was published in May 1974 in
IEEE Transactions. By Dec 1974, a complete TCP spec was published in Dec
1974 (RFC 675) written by Cerf, Yogen Dalal and Carl Sunshine at Stanford.
Three networks made up the cohort populating the early Internet: Arpanet,
Packet Radio network and the Atlantic Packet Satellite network. The first
two-network test of the Internet protocols occurred in Summer 1976 linking
the Packet Radio network to the Arpanet and was conducted by SRI
International. The first three network test was conducted Nov 22, 1977
including Packet Radio, Packet Satellite and Arpanet. Internet went
operational on January 1, 1983.
