Protecting Multicast Sessions from Link and Node Failures in Sparse-Splitting WDM Networks

Abstract

Optical splitting capability at some nodes is necessary to get efficient multicast routing in the wavelength routed wavelength division multiplexing (WDM) networks. There is a growing interest in efficiently protecting multicast sessions against the failure of network components. We propose algorithms for protecting multicast sessions against failure of network components such as links and nodes in a network with sparse splitting and sparse wavelength conversion. The effectiveness of the proposed algorithms is verified through extensive simulation experiments.
