摘要

从电力通信网的构成出发，分析了网络承载的业务和业务重要度的重要性。提出评价业务重要度的逼近理想解排序法（TOPSIS），分析了网络中广泛存在的共享风险问题，建立了风险均衡模型，提出了共享风险链路组（SRLG）与风险均衡的电力通信网路由优化算法。引入平均业务风险、风险均衡度、阻塞-风险综合指数和SRLG剩余带宽容量占比等指标进行路由优化和性能评价。以江苏省某市的光缆路由拓扑为例进行仿真，验证了所提算法的有效性。仿真结果表明，所提算法在不增加阻塞风险的情况下，有效降低了网络平均业务风险，提高了工作路径的风险均衡度，减少了SRLG剩余带宽容量占比进而降低了共享链路的业务失效风险。

Abstract

Based on the composition of power communication network

the importance of the network-borne service and its importance degree are analyzed. Then the technique for order preference by similarity to an ideal solution (TOPSIS) method for evaluating the importance of the business is proposed. The widely existing shared risk problem in the network is analyzed

and the risk balanced model is established. In the proposed shared risk link group (SRLG) and risk balanced routing optimization algorithm for power communication network

the average service risk

risk balancing degree

block-risk comprehensive index and SRLG remaining bandwidth capacity ratio are introduced to optimize the routing path and performance. The simulation is carried out in the cable routing topology of a city in Jiangsu Province of China to verify the effectiveness of the proposed algorithm. The simulation results show that without increasing the blocking risk of the network

the proposed algorithm effectively reduces the average network service risk

improves the risk balancing degree of the working path

and reduces the remaining bandwidth capacity ratio of SRLG and the failure risk of shared links.
