Otn调度系统及故障处理方法

OTN scheduling system and troubleshooting method

Abstract

The present invention discloses an OTN scheduling system and a troubleshooting method. The method comprises a step of detecting the link between the nodes of a core layer which bears a PTN, wherein, the links between a core and the nodes are borne by at least routing cables in an OTN, a step of switching the routing cable which bears a fault link when the link fault between the core nodes is detected. By using the invention, the problem that the service protection can not be carried out when an L2VPN and an L3VPN are failed at the same time or the L3VPN has two point faults can be solved.
本发明公开一种OTN调度系统及故障处理方法;方法包括:检测承载PTN的核心层核心节点之间的链路;其中,所述核心及节点之间的链路由OTN中至少两个路由光缆承载;检测到所述核心节点之间的链路出现故障时,倒换承载故障链路的路由光缆。采用本发明,能够解决在L2VPN和L3VPN同时故障或L3VPN出现双点故障时无法进行业务保护的问题。
