Abstract

Existing protection mechanisms to rapidly recover the failures allocate the backup path just SRLG-disjointed with working path. However, these mechanisms have the low resource utilization because the resource is not shared among the backup paths. To complement it, Kini (Kini et al., 2002), Somdip (Somdip et al., 2001) and so on, have proposed the mechanisms to share the resources of the backup paths. Although these mechanisms can improve the efficiency of bandwidth usage, those did not consider the unbalanced resource share of backup paths. The backup paths can be centralized on the specific link so that the idle resource is not used. As a result, as those do not use the resource efficiently the whole resource utilization is not good. So we propose the mechanism to enhance the resources utilization as settling down the unbalanced resource share to recover simultaneous failures. We formulate the problem to minimize the number of the used backup resource (exactly, wavelengths) as considering the maximum link load. We compare the existing mechanisms with our mechanism by the spare resource capacity as the result of the simulation.
