Abstract

The dynamic traffic assignment problem in WDM mesh network and traps avoidance problem under shared risk link group (SRLG) constraints were studied. A protection scheme entitled mixed shared multi-paths protection (MSMPP) was proposed. MSMPP can not only effectively avoid traps, but also, differing from previous shared path protection (SPP) scheme, make the primary path, when it doesn´t work, share its bandwidth with the backup paths, so that the network bandwidth utilization is enhanced. Simulation results show that the performance of MSMPP is better than SPP.
