A queueing approach to the performance evaluation of DQDB

A queuing model for the distributed queue dual bus protocol is presented and analyzed. A queue buffer of length one and a single priority level are assumed. The state of a node is defined by the number of requests in the distributed queue before and after generation of a packet. The node average waiting time and average throughput are analyzed as functions of the node position and state in the network. The results illustrate the effect of the various parameters on the waiting time and throughput. Comparisons with simulation and analytical results are presented.<
