  • Multiple endpoint paths for point-to-multipoint (P2MP) SPVC
    Patent number: 7668079
    Abstract: A method and system for implementing Multiple Endpoint Paths (MEP) for Point to Multipoint (P2MP) calls over Soft Permanent Virtual Connections (SPVC) are provided. When a condition is detected that requires a particular endpoint to be switched to an alternate endpoint, all calls of the P2MP group that used the particular endpoint are torn down in sequence, in accordance with SPVC procedures. Once all of the calls are torn down, any calls that are enabled for MEP are re-established using the alternate endpoint to replace the particular endpoint.

  • Tracing SPVC point-to-multipoint (P2MP) paths
    Publication number: 20070091826
    Abstract: A method and system for determining the connections of a communication path are provided. Starting from a one connection point, the identity of the connection point that precedes the one connection point in the direction in which the path was established is requested from the network element on which the one connection point is located. This may be repeated until a root endpoint is reached. Some embodiments are implemented for P2MP SPVC (Soft Permanent Virtual Connection) communications.
