电力光纤通信环网的可靠路由与可靠性

Reliable Routing and Reliability of Power Optical Fiber Communication Ring Network

电力光纤通信环网搭建于底层物理光缆网上,各个环网链接由一至多根光缆内的光纤利用节点搭载而成,同时仅允许在有业务上下节点位置安置环网节点。因为一根光缆通常涵括了多处光纤,倘若不合理设计环网链接的路由,多处环网链接就会通过相同光缆,一旦这一光缆中断,将会导致部分环网业务由于工作以及保护路径均中断而很难恢复,使得环网可靠性受到影响。相关工作人员要提出一项可靠路由方法,由此确保环网工作以及保护路径不会通过相同光缆。基于此,根据电力光纤通信网的高可靠性标准,提出了一项可靠路由及可靠性测评方案,希望能够帮助可靠路由获取较高的可用度,给同行带来一定的参考价值。

The power fiber communication ring network is built on the underlying physical optical cable network.Each ring network link is carried by one to more optical fiber utilization nodes in the optical cable,and only the ring network nodes in the upper and lower nodes are allowed.Because an optical cable usually contains multiple optical fibers,if the route of the ring network link is not reasonably designed,many ring network links will pass through the same optical cable.Once this optical cable is interrupted,it will be difficult for some ring network business to recover due to the interruption of the work and protection path,making the reliability of the ring network is affected.The relevant staff should propose a reliable routing method to ensure that the ring network works and the protection path does not pass through the same optical cable.Based on this,according to the high reliability standard of power fiber communication network,this paper proposes a reliability routing and reliability evaluation scheme,hoping to help reliable routing to obtain high availability and bring certain reference value to peers.
