  • Enhanced forwarding database synchronization for media access control addresses learned in interconnected layer-2 architectures
    Patent number: 10305796
    Abstract: A method, in a switch in an interconnected layer-2 architecture, is disclosed for enhanced forwarding database synchronization of Media Access Control (MAC) addresses based on HIT logic. The method includes learning a MAC address against a port associated with the switch; storing the MAC address with information comprising a port Identifier (ID), a switch ID, and the enhanced HIT logic set to true; setting the enhanced HIT logic to false if the MAC address was not seen on the port at an end of a cycle; and synchronizing the MAC address with other switches in the interconnected layer-2 or multi-chassis architecture if the enhanced HIT logic is true at the end of the cycle.

  • Continuity check systems and methods using hardware native down maintenance end points to emulate hardware up maintenance end points
    Patent number: 10044606
    Abstract: A node configured to emulate a hardware UP Maintenance End Point (MEP) using one or more DOWN MEPs includes a plurality of ports; a switching fabric configured to switch data between the plurality of ports; and processing circuitry communicatively coupled to the plurality of ports and configured to emulate an UP MEP on a first port of the plurality of ports using at least a first DOWN MEP on a second port of the plurality of ports. The DOWN MEP can be implemented in hardware on the second port and the processing circuitry can be configured to execute application software configured to emulate the UP MEP.

  • Systems and methods for setting up end-to-end traffic engineered ethernet line services
    Patent number: 9485161
    Abstract: A method, a switch, and a network includes receiving a request for an Ethernet service at a Maintenance End Point (MEP) in a network, wherein the Ethernet service has a destination of a Remote MEP (RMEP), and wherein the request includes bandwidth amounts for the request; utilizing Link Trace messaging to the RMEP to detect an active path to the RMEP; and utilizing Loop Back messaging to the RMEP to reserve bandwidth based on the bandwidth amounts on the active path.
