ABSTRACT:
A method of re-establishing a connection for a communication link is provided. The link has first and second portions, having the first portion in a first communication network, the second in a second communication network and an interface connecting first portion to the portion. The first communication network has a first communication protocol and a first OAM protocol to monitor integrity of the first portion. Similarly, the second communication network has a second communication protocol and a second OAM protocol. The method utilizes the second OAM protocol to detect a failure in the second portion. Upon detection of the failure, an alternate route for the second portion in the second communication network is identified, where the alternate route is able to complete the second portion of the communication link from the interface. For the communication link, at the interface the second portion is replaced with the alternate route.
