Abstract

In this paper we present a detailed performance evaluation of the carrier sense multiple accesstype MAC protocol with collision avoidance in a new optical burst-mode metro network architecture. We introduce a new analytical performance model for this MAC protocol which is exact for the slotted operation mode and from which good upper and lower bound for the unslotted operation mode can be derived. Then, we validate the analytical model by simulation and discuss the principle behavior. Key design parameters like slotted/unslotted operation mode and burst size distribution are evaluated. Finally, we assess the fairness with respect to node position by looking at the node-to-hub delay.
