Cambridge Ring
The Cambridge Ring was an experimental local area network that was developed in 1974 at the Computer Laboratory of the University of Cambridge and used until the 1980s. It was a ring network similar to the Token Ring, with a theoretical limit of 255 nodes (although such a large number would have severely impacted performance) around which a fixed number of packets would run. Free packets would be “loaded” with data from a computer trying to send, marked as received by the destination computer, and “unloaded” on return to the sender; in principle there could be as many simultaneous transmitters as there are packets. The network ran over two twisted pair cables (plus a fiber optic section).
People connected to the project included Andy Hopper , David Wheeler , Maurice Wilkes, and Roger Needham .
In 2002, Cambridge University Computer Laboratory established a graduate society named after Cambridge Ring called the Cambridge Computer Lab Ring.
