Abstract

It is shown that asymmetric WDM all-optical routers architectures are the best candidates to reduce hardware volume and cost of all-optical networks. We show that due to the non-uniform network traffic behavior, routers require asymmetric wavelength conversion capabilities and also asymmetric buffering capacity to solve contention. This paper shows that due to the topology, packets may generate traffic bottlenecks produced by a tendency of the routing scheme to send packets with different destinations through preferred paths.
