Abstract

This paper addresses the problem about how to deploy different protection strategies in the multi-layer network to use resource efficiently and give protections perfectly. Generally, every protection strategy has its own merits and demerits. How to use the merits of the protections efficiently and avoid the demerits as much as possible. For this aim, giving different protections to different LSP requests is a good selection. In this paper, we define different classes of LSP requests in terms of transmission delay and give different protections to different classes of LSP requests. Then, we propose a novel QoS-aware multi-layer protection scheme which consider the o-e-o conversion and the hop for the high priority requests at the same time and only consider the hop for the low priority requests. Moreover, we present a new inter-class backup resource sharing strategy within the scheme. It allows low priority requests to use the backup space of high priority services and also allows the high priority request use all of the resource of the network firstly as the blocking probability increasing. A complete set of experiments proves that this scheme can effectively decrease the blocking probability and end-to-end delay, comparing with the multi-layer protection scheme without inter-class backup resource sharing.
