基于配电通信网的光纤网络故障监测与恢复研究

Monitoring and Recovery of Optical Fiber Network Fault Based on Distribution Communication Network

随着配电通信网的快速发展,通信网络的可靠性和稳定性成为研究的热点。如何监测到网络中的故障以及在故障发生时如何实现网络的恢复成为可靠通信的关键。为此,文章提出了一种单核环形配电通信网络模型,并在此网络模型的基础上提出故障管理算法,该算法将配电通信网中的故障分为4类,首先根据不同的监测信息确定故障的类型,之后根据不同的故障类型利用故障管理算法进行网络恢复。评估表明,与现有的通信网络相比,文章提出的单核网络模型和故障管理算法在可靠性、速度和扩展性方面具有更好的性能。

With the rapid development of distribution communication network, the reliability and stability of the communication network has become a hot spot of research. How to detect fault in a communication network and how to recover the network in the fault occurs become the key to reliable communication.Therefore, this paper proposes a single-core ring distribution network model and fault management algorithm is proposed on the basis of which, the algorithm of distribution communication network fault can be divided into four categories. First of all, fault types are determined according to the different monitoring information, on the basis of which, we can make use of fault management algorithms to restore the network.The result shows that compared with the existing communication network, single core network model and fault management algorithm proposed in this article have better performance in reliability, speed, and expansibility.
