  • Router aggregation
    Patent number: 9077663
    Abstract: A router programmed to function within an aggregation of a plurality of routers that appears as a single router externally is programmed to determine whether it is a first router in the aggregation of routers to receive a data packet. If the router is a first router in the aggregation of routers to receive a data packet, the router is programmed to perform layer 3 routing for the data packet including modification of the source and destination Media Access Control (MAC) addresses of the packet, and then transmit the packet to another router in the aggregation of routers for layer 2 switching of the packet. If the router is not a first router in the aggregation of routers to receive a data packet, the router is programmed to only perform layer 2 switching of the packet, with layer 3 routing for the data packet having already been performed by another router in the aggregation of routers.

  • Label switched path OAM wrapper
    Patent number: 8971189
    Abstract: Methods and devices for logically segmenting an LSP so that OAM DTUs may be used to determine the performance and/or the status of LSP segments. To segment a previously determined LSP, a dedicated subpath (a logical LSP) within that predetermined LSP is defined between two LSRs that are capable of processing OAM DTUs. The source node (source LSR) establishes a logical LSP between itself and the destination node (destination LSR) using an LDP. In doing this, the logical LSP traverses a specific path and transits through specific nodes in that path. The source node then transmits an OAM DTU or any other specialized DTU to the destination node using a label specifically associated with the logical LSP that was established. The characteristic of the specific path traversed by the logical LSP can thus be determined by when, how, and if the specialized DTU is received by the destination node.
