Paper Abstract

A novel restoration scheme for multi-failures based on protection ring with dynamic weight (PRDW) is proposed in this paper. This scheme effectively resolves the multi-failures which is in one service and the conflicts by restoration between services. PRDW use Dijkstra's algorithm to compute path and protection ring. These rings rely on protection weight which is dynamic, so that they can as much as possible to divide multi-failures to single ones. Meanwhile PRDW introduce independent protection weight to balance load, which effectively gets combat for resources less vicious. Simulation results show that PRDW works better than traditional schemes.
