基于故障链路资源分离的电力光缆备用路由资源配置方法

为了保障电网远程调度通道的可靠性，同时提高光缆网络资源的利用效率，基于共享备份通道保护方法耗费资源量大、阻塞率高等问题，提出一种基于故障链路组分离的资源配置方法，在构建保护通道时，根据所形成的资源链路组进行保护资源的配置管理，将主路由、备用路由的资源进行标记，采用分组配置方式提升备用通道的利用效率，从而实现主用工作路由资源的节省.最后，针对不同的网络仿真场景对所提出的方法进行验证，并对性能指标进行了理论分析.

Backup Resource Allocation Approach for the Electric Power Optical Network Based on Failure Group Separation

In order to ensure the reliability of the remote dispatching network and improve the utilization efficiency of optical cable network resource, this paper presents a resource allocation approach based on fault link group separation to solve the problem of high resource cost and block probability of shared Backup Path Protection approach. In the construction of protection channel, management of protected resources can be allocated according to the formation of the resource link group. It utilizes the main routing and alternate routing tag to improve the utilization efficiency of backup channel, realizing the saving of the main working route resource. Finally, the proposed method is verified under different network simulation scenario, and the performance is also analyzed in theory.
