DSMA: a fair capacity-1 protocol for gigabit ring networks

The authors present a simple MAC-level protocol for high-speed ring networks. The protocol is fair and its maximum achievable throughput does not deteriorate with the increasing propagation length of the ring. The proposed protocol operates on the so-called `spiral ring´ topology, including the single-segment regular ring as a special case. It accommodates synchronous traffic automatically, without any bandwidth preallocation or similar special efforts, yet with an arbitrarily low jitter and without packet loss
