Abstract
In this work, we propose a novel protection strategy for IP-over-WDM networks. This new strategy maximizes the amount of protected traffic while providing fast recovery times. It assumes coordination between the IP and the WDM layer provided by GMPLS in a peer model. IP LSPs aggregated into a lightpath (high capacity LSP) are protected together, as a unity, using spare capacity of edge-disjoint lightpaths whenever necessary. While protection is provided at the lightpath level offering fast recovery times, this scheme also allows the use of the spare capacity of working lightpaths.
