Paper Abstract

As WDM technology becomes mature, the number of wavelengths in WDM systems continues to increase, which will increase the complexity and costs of the switching fabrics in OXCs. As a result, multi-granularity (MG) optical network is introduced, which will significantly reduce the provisioning cost in optical domain. An important network design problem in MG networks is to provide survivability in the event of a failure. In this work, two shared protection schemes called SPPB (shared protection per bandpath) and SPPL (shared protection per lightpath) are proposed for protecting lightpaths against single link failure in multi-granularity optical networks. Some GRWA algorithms for SPPB and SPPL are also proposed. Analysis and simulation are performed to evaluate these protection schemes.
