  • System and method for monitoring the connectivity of a path between nodes in a network
    Patent number: 8493872
    Abstract: A method and system for determining a path between nodes in a network are disclosed. In accordance with an embodiment of the present disclosure, a system for determining a path between nodes in a network comprises a destination node and a link aggregation group (LAG) that includes a first link and a second link. The system further comprises a source node communicatively coupled to the destination node by the LAG where the source node, the LAG and the destination node form a path. The source node is operable to determine a link availability status for each of the first and second links using a layer-2 protection scheme. The source node is further operable to monitor the path for connectivity based on the link availability status using a layer-3 protection scheme.
