Description

一种自动解除动态隧道与服务层告警关联的方法和装置 技术领域
本发明涉及电信业务承载技术, 尤其涉及一种自动解除动态隧道与服 务层告警关联的方法和装置。 背景技术
随着电信业务 IP化趋势, 传输网承载的业务从以时分复用 (TDM )为 主向 IP为主转变。 分组传送、 面向连接、 多业务融合等要求相继提出, 分 组传送网 (PTN )应运而生。 多协议标签交换-流量工程(MPLS-TE )对多 协议标签交换、 伪线技术进行了简化, 引入了分层传送、 运营管理与维护 ( OAM )、 线性保护, 所以 MPLS-TE承载技术逐步演进成为主流的传输网 承载技术。 通过 MPLS-TE技术可建立端到端面向连接的分组传送管道, 该 管道具有高性能和高可靠性, 并能够利用信令和路由协议, 动态地发现网 络拓朴和资源, 动态快速地建立端到端动态隧道, 当发生故障时动态地进 行保护和恢复,所以通过 MPLS-TE控制平面建立的端到端动态隧道具有 4艮 大的灵活性。
在动态隧道业务应用领域中, 常常会将各种服务层告警定位到动态隧 道上, 从而进一步分析服务层告警影响的业务。 但服务层告警并不会一直 影响动态隧道, 因为动态隧道具有重路由特性。 一旦动态隧道发生了重路 由, 无论之前关联的服务层告警是否消失, 该告警将不再影响这个动态隧 道。 服务层告警与动态隧道关联, 如图 1所示, 网元 A、 网元 B、 网元 C、 网元 D组成的链路中, 网元 A为首节点网元, 通过网元^ 网元 C路由到 网元 D, 当网元 B与网元 C间发生链路故障时, 通过逻辑口 1与逻辑口 2 将服务层告警分别关联到动态隧道 1和动态隧道 2。 目前业界网管系统是靠告警的消失事件来解除服务层告警与动态隧道 的关联。 但是, 动态隧道发生重路由后, 因为动态隧道关联的服务层告警 可能是当前告警, 并没消失, 所以不能立刻解除该服务层告警与动态隧道 的关联, 该服务层告警将错误地反映动态隧道当前的服务状态。 发明内容
