  • Patent number: 9391799
    Abstract: In some embodiments, a global tree structure identifying rendezvous points between a layer 1 network area and a layer 2 network area may be created. When the rendezvous point receives a data packet associated with a destination for the layer 1 network area from the layer to network area, it may forward the data packet to the destination. Non-rendezvous point devices may discard copies of the data packet.
    Type: Grant
    Filed: October 18, 2012
    Date of Patent: July 12, 2016
    Assignee: Cisco Technology, Inc.

  • Patent number: 7583603
    Abstract: A distributed Link-State Routing Protocol (LSRP) system in a packet switch having external communication ports has a first card executing Update process of the LSRP, making database updates, a second card executing Decision process(Shortest Path First (SPF)) of the LSRP, and a communication fabric coupling the cards with each other and the external ports. The LSRP may be an IS-IS system. In some embodiments there are additional cards involved, and the distribution of Link-State functions is over a set of multiple cards. Also in some embodiments there is a Location Service (LS) controller monitoring and configuring cards in the system.
