ABSTRACT:
An architecture for a distributed CSMA/CD network using IEEE 802.3 protocol that is widely extended between transmitting and receiving nodes by placing some of the idle/busy/collision functions in one or more protocol control nodes which are located between the other nodes. The protocol control nodes do not perform resynchronization and are not bridge nodes, so their use does not cause any time delays. One application would be a cable TV system where the distant nodes would be the cable office node that is widely separated from a group of neighborhood local nodes. A protocol control node intermediately placed in close proximity to the local nodes provides the idle/busy/collision control functions while allowing the central office node to be located beyond the IEEE 802.3 maximum distance.
