Abstract
Traffic grooming techniques in optical networks are attracting increasing research attention in order to handle the huge bandwidth mismatch between high capacity lightpaths and low-rate individual traffic requests. It is important to have guaranteed survivability of all user connections in such networks. There are two popular schemes in use for the protection of WDM networks against any optical link failure--Dedicated Path Protection and Shared Path Protection. However, these schemes require pre-allocating resources for backup lightpaths at design time. Recently, a new scheme has been proposed where every link failure scenario is taken care of when designing a robust logical topology. In our research we have used heuristics to implement this new scheme considering non-bifurcated traffic grooming, and have compared our approach with path protection schemes. Experimental results show that, in respect of network resources utilization, our scheme clearly outperforms both Dedicated Path Protection and Shared Path Protection schemes.
