Abstract
Recently, many heuristic algorithms have been put forward for protecting the multicast session against any single link failure in a WDM mesh network. But for the same session, the strategy is same. For the first time, in this paper we propose a novel technique to blend two classes of strategies in a hybrid recovery approach. Using this technique the multicast session is divided into two parts through a parameter called threshold. One is critical tree, the other is uncritical tree. These two parts are recovered by using two different sharing strategies of backup resources. We perform simulations to study static provisioning of survivable multicast sessions in a WDM mesh network with sparse light splitting and detailed simulations results are shown.
