Abstract

Traditionally link/path protections are widely used means to assure network survivability. Recently sub-path flow-based and sub-mesh topology-based segmentation protection methods are proposed. In this paper, we propose improvements to the sub-mesh-based approach which include potential capacity estimation, adaptive group reconfiguration and corresponding control signaling mechanisms. We consider mainly the dynamic group protection strategies under dynamic traffic demands and examine the relative influence of various network metrics. Simulated performance results for the proposed heuristics are given and discussed.
