A method of non-service affecting APS protection for MLPPP bundles on routing systems, and associated mechanism, including one or more of the following: specifying a working MLPPP bundle and a protection MLPPP bundle; specifying MLPPP parameters; associating the working MLPPP bundle and the protection MLPPP bundle with an APS circuit; bringing up an MLPPP session; changing an operational status of the working MLPPP bundle; synchronizing MLPPP state information between the working MLPPP bundle and the protection MLPPP bundle; and driving an operational status of the protection MLPPP bundle based on said changing the operational status of the working MLPPP bundle.

A mechanism and method for efficient endpoint discriminator allocation for APS protected MLPPP bundles on distributed routing systems, including one or more of the following: specifying working and protection MLPPP bundles; retrieving an endpoint discriminator for the working bundle and updating an endpoint discriminator of the protection bundle based on same; specifying MLPPP operating parameters for the bundles; associating the bundles with an APS circuit; adding links and corresponding discriminators in an LCP between a near end bundle and a far end bundle; bringing up an MLPPP session; and adding links between bundles upon an APS switchover.

A method of collecting consistent flow statistics through multiple congestion points within a multi-service switch/router is enabled by computing a payload length of each traffic unit received from a fabric of the switch/router. A PHY-level header containing the payload length, a class of service and a service ID is appended to the switch-internal encapsulated payload. Information associated with the PHY-level header is used at physical level congestion points to collect consistent flow statistics.
