Research output: Contribution to journalArticlepeer-review


Token bus protocols have been widely accepted for medium access control (MAC) in computer networks. The priority scheme in token bus protocols offers multiple levels of privilege of medium access to heterogeneous traffic. Performance evaluation of the priority scheme is essential for design and operation of real-time networks such as those used in aircraft and factory communications. This paper presents the results of statistical analysis of the network-induced delays at all priority levels and their verification by simulation experiments. Use of the analytical model is illustrated for initial design of the network as well as for optimization of its performance.
