Abstract

One of the ways to offer QoS in optical networks, in a policy-based environment, is to use route protection policies. For each signed contract, the network administrator defines the type of protection (1:1, 1+1 or l:n) through service classes (gold, silver, bronze). However, the pre-planned backup routes can be inadequate to guarantee the SLA (service level agreement). In case of failure, there is no way to guarantee that the choosen protection route will meet the client requirements. In this paper, a method for choosing the best backup route is proposed through genetic algorithms and PBM, called GEAP.
