The S++ Mac protocol

Watson, Greg



Abstract: In this paper we describe the S++ protocol, a new protocol designed for Gbit/s LANs. The S++ protocol has evolved from our experience with an earlier protocol, called S, which was implemented in the HANGMAN Gbit/s LAN project. The characteristics of a MAC protocol that we deem to be essential for a high speed-network include low access delay and efficient utilization of resources. We present simulation results for S++ and we compare its performance to that of another MAC protocol, DQDB.
