Abstract
Recently, Local Area Networks carrying multiple priority classes of messages have received considerable attention. The IEEE 802.5 token ring standard defines an optional priority scheme to handle different priority classes of messages. A simulation model of symmetric priority based networks, consisting of token ring networks interconnected by a bridge is considered. Messages are divided into two priority classes, namely, high priority traffic and low priority traffic. High priority traffic is guaranteed access on the channel, whereas low priority messages are served when the system determines that no high priority messages are currently waiting. The simulation results are used to evaluate the throughput and delay characteristics of intra- and inter-network traffic for both priority classes. The results indicate that; the protocol has favorable properties at the extreme loading conditions. in terms of bandwidth allocation to each class of traffic. However, such results also provide guidelines for selecting the system parameters to satisfy specific application requirements.
