Abstract:
A method, apparatus and computer program product for implementing port selection via synchronized port state databases maintained by the forwarding plane of a network element is presented. Each Forwarding Data Unit (FDU) within the forwarding plane of the network element maintains a respective port state database, each port state database containing a synchronized view of the port state for all ports within the network element. A port selection process is performed by each port state database upon request of its associated FDU, to identify an available port in an UP state associated with a Multi-Link Trunk (MLT) to enable fast reroute between ports associated with the MLT in the event of port failure. The process returns an identified port to the FDU for use by the FDU to forward the packet.
