Abstract:
1. A method for efficient endpoint discriminator allocation for Automatic Protection Switching (APS) protected Multi Link Point-to-Point Protocol (MLPPP) bundles on distributed routing systems, comprising: specifying a working MLPPP bundle; specifying a protection MLPPP bundle; retrieving an endpoint discriminator for the working MLPPP bundle; updating an endpoint discriminator of the protection MLPPP bundle based on the retrieved endpoint discriminator for the working MLPPP bundle, wherein the endpoint discriminator is unique and pre-allocated for the working MLPPP bundle and the protection MLPPP bundle; specifying MLPPP operating parameters for the working MLPPP bundle and the protection MLPPP bundle; associating one or more bundles with an APS circuit; adding one or more links between a near end bundle and a far end bundle; providing one or more discriminators in a Link Control Protocol (LCP) for the one or more links added between the near end bundle and the far end bundle; bringing up an MLPPP session; and adding one or more additional links between the near end bundle and the far end bundle upon an APS switchover.
