摘要
电力通信系统中的电力特种业务,特别是继电保护业务,对于通信信道的时延有着较高的要求,传统的SDH网络已经越来越不能满足其需求。本文针对业务特点,在分析了其通道延时、双向通道延时差的相关特性后,设计了一种新的ASON路由算法。仿真实验表明,该路由算法较好地实现了双向路由的寻找,并且找到的路径的时延小,算法时间复杂度低。算法很好地满足业务需求,实现了其承载。
The special electric service in the electric communication system,especially the relay protection,have a high demand about the time delay,the traditional SDH networks have been increasingly unable to meet their needs.This paper aims the demand of the special elctric service,analyses the delay of the service path、duplex channel delay jitter,and designs a new ASON routing algorithm.The result of the simulation shows that the algorithm can successfully find the duplex route, the route’s delay is small,and the time complexity is low.So it satisfy the demand and achieve the load.
