This paper addresses some performance modelling issues arising from the inter-processor messaging requirements of distributed real-time processing systems. We consider two basic classes of message transfer protocols, namely clocked schemes where message transfer is initiated as a periodic timed task, and event-driven schemes where the transfer mechanism is(More)
This pape'r describes an approach for the performance modelling and queueing analysis of the priority access mechanism contained within the Medium Access Control layer of the ANSI/IEEE 802.5 token ring local area network protocol. The performance model is a multiqueue polling system with two priority levels and exhaustive service at each station, and(More)
