Optimizing the QoS Performance of Fast Rerouting

摘要：

A fast rerouting scheme is proposed to guarantee the QoS performance of rerouted path when handling link and node failures. The new scheme is based on deflection routing mechanism and improves on two aspects: first, it can promptly handle single node failure as well as single link failure, second, QoS metric is taken into accounted when calculating recovery routes. Simulation results show that the proposed scheme could achieve as optimal performance as constrained Bellman-Ford algorithm.
