  • Method and apparatus for virtual circuit routes
    Patent number: 8565232
    Abstract: A method and apparatus for virtual circuit routes is described. A method in a network element comprises associating a virtual circuit to a layer 3 next hop, the virtual circuit being associated with a layer 2 protocol specific logical circuit, receiving a packet on the logical circuit, processing the packet with configuration information indicated by the virtual circuit, and forwarding the packet to the layer 3 next hop associated with the virtual circuit without processing the packet's layer 3 header.
    Type: Grant
    Filed: March 27, 2012
    Date of Patent: October 22, 2013
    Assignee: Ericsson AB
    Inventors: Rahul Aggarwal, Ajay M. Patel

  • Method and apparatus for a routing information base
    Patent number: 7035256
    Abstract: A method and apparatus for managing an information routing information base is described. A method comprises managing a routing information base (RIB), the RIB including a first set of elements that indicate a set of destinations, a second set of elements that indicate a set of next hops, a third set of elements that indicate a set of interfaces, receiving a message that indicates a modification to a plurality of routes corresponding to a plurality of the first set of elements, and modifying a first relationship between one of the second set of elements and a first one of the third set of elements and a second relationship between the one of the second set of elements and a second one of the third set of elements in accordance with the message, the one of the second set of elements referenced by the plurality of the first set of elements.
