چکیده انگلیسی
The survivability in optical WDM networks is an important issue and has been studied for many years. This paper addresses the protection for the single-link failure in optical WDM networks and proposes a new and improved algorithm called Near Optimal Routing (NOR). For each connection request, the previous algorithm first computes one primary path and follows to compute one link–disjoint backup path. In our proposed algorithm, NOR can obtain the near optimal solutions by re-computing the primary or backup paths based on the rerouting policy. Simulation results show that the performances of NOR can be significantly improved compared to the previous algorithm.
