A new approach to concurrent ring: 1 bit latency

Abstract

This paper presents new ideas about concurrent ring (new model for the standard IEEE 802.5). Concurrent Ring is a LAN based on a token ring access method that uses a multiple transmissions scheme. It introduces a new concept for the transmission protocol. It has a good throughput response and a stable response with high workloads. With regard to other approaches like parallel-ring It has a severity disadvantage: its high station latency (16 bits). In this paper we introduce a new model with only 1 bit latency per station and a error recovery scheme. However, simulation studies show that Concurrent Ring (I bit latency) behaviour for high workloads offers a better throughput characteristic than the standard IEEE 802.5. This new approach of concurrent ring has a better receipt time-throughput than Parallelring and Pronet.
