二纤通道保护环自愈分析

Self-Healing Analysis of Two-Fiber Channel Protection Ring

光传输网络作为现代通信的基础承载网络,其稳定性和可靠性至关重要。一旦发生故障,将会对所承载的业务造成严重影响。而环型网络拓扑结构由于网络保护机制丰富、实际操作性强以及成本低等优势,被广泛应用于光传输网络。对二纤通道保护环的保护机制进行分析对比,区分双向和单向2种方法,并阐述其实现自愈的过程。

As the basic carrying network of modern communication,the stability and reliability of optical transmission network are very important.Once a fault occurs,it will have a serious impact on the business it carries.The ring network topology is widely used in optical transmission networks because of its rich network protection mechanism,strong practicality and low cost.In this paper,the protection mechanism of two-fiber channel protection ring is analyzed and compared,and two methods,bidirectional and unidirectional,are distinguished,and the process of self-healing is expounded.
