Applying Saturated Cut Method in Dynamic Multicast Traffic Grooming in IP/MPLS over WDM Mesh Networks

Abstract

Handling low and medium speed traffic flows using cost-effective traffic grooming strategies is becoming increasingly important for the efficient operation of WDM networks. In this paper, we apply the saturated cut method to routing sub-wavelength multicast traffic in reconfigurable, unicast, mesh WDM networks. Simulations show that setting up lightpaths for the saturated cut significantly improves network-blocking performance
