Swing: Traffic capacity of a simple WDM ring network

摘要

The paper presents a novel MAC protocol for a ring packet-switched WDM network. The protocol is based on both opportunistic access ensuring efficient utilization of slots and dynamic reservations that maintain a certain degree of fairness between stations. We show that, while a purely opportunistic access scheme is perfectly efficient, the impact of introducing the proposed reservation algorithm is limited in terms of lost capacity in any realistic traffic scenario.
