摘要

电力OTN（光传送网）的业务风险与链路和节点的失效概率以及业务路径配置类型存在复杂的依赖关系。为了确定不同因素对业务风险的影响程度

需要采用有效的方法对业务风险及其影响因素进行相关性分析。文章首先给出了电力OTN业务风险模型和分析方法

并针对链路和节点失效场景进行了业务风险分析;然后确定了6项业务风险影响指标

并采用Spearman秩相关系数法对影响指标与业务风险间的相关性进行了分析;最后实例验证了风险分析和相关性分析算法的可行性。研究结论对电力OTN业务风险评估以及业务路径优化配置具有参考价值。

Abstract

There exist complex dependencies between electric power Optical Transport Network（OTN）service risk factors and link or node failure probability and type of service path configuration.In order to determine the influence degree of different factors on the service risks

it is necessary to adopt effective methods to analyze the correlation of service risks and their influence factors.This paper first gives the service risk model and the analytical approaches and analyzes the service risks in the failure scenario of the links or nodes.Then

it defines six service risk influence indicesand analyzes the correlation between the influence indices and the service risks using the Spearman’s rank correlation coefficient method.Finally

it verifies the feasibility of risk analysis and correlation analysis algorithmin practical cases.The research conclusions have certain reference value to OTN service risk assessment and service path optimized configuration.
