基于综合机制的光网络恢复方法的研究

A Study of Integrated Restoration Approach in Optical Networks

提出了一种光网络恢复的综合机制,该机制将基于网元的恢复方法、基于网络管理系统的恢复方法和改善的基于网元的恢复方法综合起来进行使用,减少了单独使用各恢复方法的缺点,从而满足不同业务运行质量的要求.

The survivability of network is an optical network's capability to meet the QoS(quality of service) requirement that has been affected due to failures of the network resources. One new approach in optical networks based on the concept of hybrid NE(network element) based and NMS(network management system) based method is proposed. In the approach proposed, there are three restoration methods which is the NE based, the NMS based, and enhanced NE based method, each of which can supply different critical parameters for restoration.
