Abstract

The paper considers the problem of establishing robust routes for multi-granularity connection requests in traffic-grooming WDM mesh networks and proposes a novel Valiant Load-Balanced robust routing scheme for the hose uncertain model. Our objective is to minimize the total network cost when assuring robust routing for all possible multi-granularity connection requests under the hose model. Since the optimization problem is recently shown to be NP-hard, two heuristic algorithms are proposed and compared. When implementing Valiant Load-Balanced robust routing scheme to WDM mesh networks, a novel traffic-grooming algorithm called MHF (minimal hop first) is proposed. We evaluate MHF by Valiant Load-Balanced robust routing with the traditional traffic-grooming algorithm by computer simulation.
