省级电力OTN光网络波道利用率提升研究

Research on Channels Utilization Rate of OTN Backbone Optical Network in Anhui Electric Power

安徽电力OTN骨干通信网为40×10G系统,网络架构为“田”字型,主要承载数据通信网10GE通道,且所有电力数据通信网业务均汇聚至省调和省备调,整网已使用了37个波道,部分环中的波道占用比例高达85%,剩余波道资源已难以满足新建站点业务接入。通过对安徽公司OTN骨干通信网进行分析,结合“十三五”规划中新增的光缆和站点资源,调整波道路由,对OTN骨干网进行优化,平均波道占用比例由73%降至62.5%,提升了OTN波道资源利用率。

Anhui Electric Power OTN backbone communication network is a 40×10G system.The network architecture is“Tian”type,which mainly carries 10GE channels of data communication network,and all power data communication network services are aggregated to the provincial and provincial adjustments.The whole network has been used 37 channels,the proportion of channels in some rings is as high as 85%,and the remaining channel resources are difficult to meet the service access of new stations.This paper analyzes the OTN backbone communication network of Anhui electric company,combines the newly added optical cable and site resources in the"13th Five-Year Plan",adjusts the wave path,optimizes the OTN backbone network,and reduces the average channel occupancy ratio73%to 62.5%,which improves the utilization of OTN channel resources.
