摘　　要：波长交换光网络(WSON)是基于波分复用传输网的自动交换光网络,可实现大容量、端到端的全光网通信,WSON智能化的关键是加载控制平面并具有保护与恢复功能,即收到告警之后进行自动保护倒换。文中研究了光网络的生存性,并提出一种新的OA-OSC联合告警算法,文中主要说明该算法的设计原理,并基于验证OA-OSC联合告警算法合理性这一目的,采用对比观察的方法构建五节点拓扑进行实验,实验证明了该算法与传统告警相比,减少了业务倒换所需时间,且该算法有利于系统进行链路管理,可进一步提高光网络的生存性。Wavelength Switched Optical Network(WSON) is an automatic switched optical network based on wavelength division multiplexing transmission network,which can realize high-capacity,end-to-end all-optical network communication. The key to WSON intelligence is to load the control plane and have the function of protection and recovery,that is,automatic protection switching after receiving an alarm.This paper studies the survivability of optical network,and proposes a new OA-OSC joint alarm algorithm.This paper mainly explains the design principle of the algorithm. Based on the purpose of verifying the rationality of OA-OSC joint alarm algorithm,a five node topology is constructed by comparative observation method for experiments. It is concluded that this algorithm reduces the time required for service switching compared with traditional alarm. And the algorithm is conducive to the system link management,and can further improve the survivability of optical networks.
