摘要：

In this paper, we address the problem of survivable traffic grooming and regenerator placement in optical WDM networks with impairment constraints. The working connections are protected end to end by provisioning bandwidth along a sequence of lightpaths by using a shared connection-level protection scheme. An auxiliary-graph-based approach is proposed to address the placement of regenerators and grooming equipment for both working and shared backup connections in the network with the goal of minimizing the total equipment cost. Simulation results show that the proposed algorithm outperforms the dedicated connection-level protection algorithm as the load increases.
