✦ Synopsis

This paper presents a performance study for a class of token passing networks which allow the token rotation time (TRT) limit to be adjusted dynamically in accordance with the type of delay-sensitive sessions in progress. Results show that the dynamic scheme allows higher throughput to be attained compared to a static scheme, under most circumstances. However, when the switching overheads are comparable to cycle latency, the frequent establishment and tearing down of delay-sensitive sessions may cause excessive adjustments and result in lower throughput.
