CHAOSnet was the name for both an internetworking 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.
