An adaptive algorithm to ensure differential service in a token ring network

A distributed and adaptive token-passing algorithm which can be used to maintain the mean waiting times at the hosts of a token-ring network at a prescribed ratio is presented. The algorithm is simple to implement, and simulation results indicate that it performs well. The algorithm can also be easily modified for other purposes; in this study the authors demonstrate its use in controlling the throughput arising from multiple job classes and in integrating voice and data packets on the same ring.<
