基于GMPLS具有优先级属性的智能光网络生存性协调策略

In this paper，through the research of Network survivability and multi-layer network survivability strategy, presents a superior strategy for the cross-layer coordination ,with the integrated control plane technology based on Generalized Multiprotocol Label Switching(GMPLS) and the improvement of Resource ReSerVation Protocol-Traffic Engineering(RSVP-TE). By matching the fault to the state of the node, achieves "first discover, first deal with". By using the priority, achieves "choose the optimal solution quickly". It is shown by simulation that this strategy can slove the problem well which can not be solved in the coordination of multi-layer network. And this strategy can greatly improve the recovery of multi-layer network survivability efficiency and flexibility.
