基于指标体系的传输网SDH服务风险分析方法
|
摘要
本文提出一种基于故障概率的电力通信网的风险分析方法,根据操作风险的特殊性及其自身的特点,设计了大容量传输网SDH(Synchronous Digital Hierarchy,同步数字体系)的多因素综合指标体系评价指标。本文根据设备和光缆中承载的业务情况,直接计算光缆段或者设备节点故障对相关承载业务的影响,得到的是网络中业务的绝对损失量。通过仿真实验证明,该方法计算方式简单,对网络规模的适应性较好,应用性较强。
Based on the particularity of operational risk and its own characteristics, this paper designs a multi-factor comprehensive index system evaluation index for large-capacity transmission network SDH. This article directly calculates the impact of faults on the cable or equipment node to the related bearer services based on the service conditions carried in the equipment and optical cable, and obtains the absolute loss of services in the network. Simulation experiments show that the method is simple in calculation, adaptable to network scale and strong in application.
