Abstract

We propose to study the performance of an unslotted optical MAN ring operating with asynchronous variable length optical packets. Source stations are connected to the optical ring. They take electronic packets coming from client layers and convert them into optical packets. The MAC protocol is based on the synchronous “empty slot” procedure. The performance model of the ring is based on an M/G/1 queue whith multiple priority classes of packets, and a preemptive Repeat-Identical service policy. Using the busy-period analysis technique, joint queue-length probability distribution is computed and exact packet delays at each source are given for different packet length distributions. Practical applications of the model are considered in order to see the impact of input parameters (packet length distributions, rank of the station) on performance measures.
