Impact of multi-port card diversity constraints in mesh optical networks
Abstract
We model and measure the impact of multi-port cards and circuit-pack diversity constraints on the routing of protected lightpaths in optical networks and the resulting network capacity. We describe an offline routing and channel assignment algorithm combined with a multiport card configuration algorithm, and experiments with these algorithms on various network designs. We show in particular that the impact is negligible, even in the case of shared-mesh protection architectures protecting against single multi-port card failures. © 2005 Optical Society of America.
