Abstract

A queuing subsystem is proposed to the round robin receiver/transmitter (R³T) optical code-division multiple-access (OCDMA) protocol. The corresponding state diagram and its mathematical model are outlined. We prove that significant improvement in terms of system throughput and blocking probability can be achieved by only adding a single buffer at each user node. Furthermore, the modified R³T protocol can support higher traffic loads with acceptable delay and good efficiency.
