    摘要: The present invention discloses a maintenance method for ASON system when service generates an alarm, which comprises: after a service is successfully established, a head node setting a local alarm monitoring and respectively requesting an intermediate node and a tail node to set an alarm monitoring; and the intermediate node and the tail node setting their own local alarm monitoring according to the requests of the head node,; when the intermediate node and/or the tail node generates an alarm, notifying the head node of the alarm information which affects the service; according to the received alarm information, the local alarm information of the head node and a protection and restoration strategy pre-configured by the head node, the head node setting a service maintenance strategy and a service maintenance operation, and notifying the service maintenance strategy to the tail node; the head node and the tail node carrying out corresponding maintenance operation according to the service maintenance strategy.

    摘要: A method and apparatus that proxies connectivity check messages and sends fault state changes messages across an MPLS/VPLS network is described. A network element proxies connectivity check messages for remote maintenance endpoints based on a local database. The network element updates the database based on received fault state change message that identify a fault state change of a remote maintenance endpoint. The network element detects fault state changes of local maintenance endpoints and sends a fault state change message to other network elements that proxy connectivity check message for the local maintenance endpoints.
