无源光网络冗余保护及应用实现

Passive optical network redundancy protection and application implementation

PON网络相对于传统网络组网简单,无源传输,提供可观接入速率和多业务应用,得到了蓬勃发展。通过对PON网络组网结构以及业务特征的定性研究,分析了PON网络中不同保护方式对应的应用场景。并对在网络设计中考虑保护以及在组网各个节点进行冗余保护以及提升网络运行稳定性,提高用户体验感知的有效方法进行了总结。并对特殊应用下的PON网络结合和冗余保护实现进行分析总结。

Compared with traditional networks, the PON network is easy to be interworking. Passive transportation can provide substantial access rate and mulit-service applications, and it has been developed greatly.Through qualitative researching of the PON network’s networking structure and service characteristics,we analyze the application scenarios that different ways of protection correspond to in the PON network. And summarize the effective methods when the protection is taken into account in network design, redundancy protection of each node in networking and how to improve the operation stability of the network, improve the user experience and perception. And analyze and summarize PON network combination and the realization of redundancy protection under special applications.
