  • Patent number: 10205602
    Abstract: Consistent with embodiments of the present disclosure, systems and methods are disclosed for providing per-group ECMP for multidestination traffic in a DCE/TRILL network. Embodiments enable per-group load balancing of multidestination traffic in DCE/L2MP networks by creating a new IS-IS PDU to convey the affinity of the parent node for a given multicast group. For broadcast and unknown unicast flooded traffic, the load balancing may be done on a per-vlan basis.
    Type: Grant
    Filed: November 30, 2017
    Date of Patent: February 12, 2019
    Assignee: Cisco Technology, Inc.
    Inventors: Santosh Rajagopalan, Ajay Kulhari, Hariharan Balasubramanian

  • Patent number: 8780904
    Abstract: A first switch of a first network may receive a second set of information including routing identifiers associated with a second network, wherein the first switch of the first network is connected to a second switch of the second network. The first switch of the first network may transmit a first set of information including routing identifiers associated with the first network. The first switch may determine whether a conflict exists between the second set of information and the first set of information. A conflicting one of the routing identifiers associated with the first or second network may be transitioned to a non-conflicting routing identifier according to the determination of whether a conflict exists between the first set of information and the second set of information.

  • Patent number: 8111691
    Abstract: Methods and apparatus for merging two or more networks are disclosed. In one embodiment, a first switch of a first network receives a second set of information including routing identifiers associated with a second network, wherein the first switch of the first network is connected to a second switch of the second network. The first switch of the first network transmits a first set of information including routing identifiers associated with the first network. The first switch determines whether a conflict exists between the second set of information and the first set of information. A conflicting one of the routing identifiers associated with the first or second network may be transitioned to a non-conflicting routing identifier according to the determination of whether a conflict exists between the first set of information and the second set of information, thereby enabling data to flow between the first network and the second network via a link between the first switch and the second switch.
