Star network with collision-avoidance circuits

This paper describes the implementation of a multiple-access star network that uses a new collision-avoidance circuit to avoid collision of packets and to take full advantage of wideband transmission systems. The analysis shows that the resulting network has a channel capacity equal to 1, has good stability under heavy traffic conditions, allows transmission of packets shorter than the network round trip time, and provides distributed switching. Collision-avoidance circuits have been built and operated up to 50 Mb/s.
