一种新的ASON故障通告机制研究

Research on a new ASON malfunction notification mechanism

为了提高自动交换光网络(ASON)的故障处理效率,提出了一种新的基于同源的ASON故障通告机制。在分析传统故障通告机制不足的基础上,阐述了新的基于同源的故障通告机制的工作流程。新的机制仅向所有同源的连接发送一次故障通告消息,降低了网络故障消息的发送次数,提高了网络的故障处理效率。仿真实验表明,与传统的故障通告机制相比,新的机制减少了网络故障通告处理时间,降低了网络的流量。

In order to improve the efficiency of malfunction treatment in ASON,a new ASON malfunction no- tification mechanism based on the same source is put forward. On the basis of analyzing the deficiency of tra- ditional malfunction notification mechanism,the working flow of a new malfunction notification mechanism based on the same source is expounded.The new mechanism only sends once malfunction notification infor- mation to all connections with the same source,so it can reduce the sending degree of network malfunction in- formation,and boost the treatment efficiency of network malfunction.The simulation experiment demonstrates that compared with the traditional malfunction notification mechanism,the new mechanism lessens the treat- ment time of network malfunction notification, and reduces the network traffic.
