This paper introduces a novel class-based method of survivable routing for connection-oriented IP-MPLS/WDM networks, called MLS-GEN-H. The algorithm is designed to provide differentiated levels of service survivability in order to respond to varying requirements of end-users. It divides the complex problem of survivable routing in IP-MPLS/WDM networks into two subproblems, one for each network layer, which enables finding the solutions in a relatively short time. A genetic approach is applied to improve the quality of results by solving the problem iteratively. Modeling results show that, after a reasonable number of iterations, a good solution (up to 22.55% better than the initial one) is found and further improvement is hardly possible.
