  • 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.
