Chaosnet

CHAOSnet was the name for both aninternetworking protocol family, and an early LAN technology, both invented at the MIT AI Laboratory; the latter was the LAN on which the protocol first ran.

The LAN was a CSMA-CD system modeled on the Xerox PARC 3 megabit/second Ethernet, running over cable TV cable. The protocol was later made to run over standard 10 megabit/second Ethernet, which largely supplanted the CHAOSnet hardware.

The protocol provided a reliable byte stream service, but also had a datagram mode.

There were implementations for at least ITS, TOPS-20, Lisp Machines, VAX/VMS, BSD Unix, and PDP-11 Unix V7.
