  • Patent number: 9094334
    Abstract: A solution for virtual router redundancy for server virtualization includes, at a network device configured as a backup router of a virtual router, examining a packet stored in a memory of the network device. Responsive to the examining, the network device determines whether to forward the packet via a network towards a destination or to send the packet via the network to a master router of the virtual router for forwarding of the packet, by the master router, towards the destination.
    Type: Grant

  • Publication number: 20140269746
    Abstract: One embodiment of the present invention provides a switch. The switch includes a link aggregation database and a packet processor. The link aggregation database stores configuration information regarding a plurality of switches participating in a multi-chassis trunk. The plurality of switches includes the switch. The packet processor constructs a packet for a remote switch. This packet is forwardable via a logical connection. The packet includes a virtual circuit label associated with a second logical connection of a second switch. The plurality of switches includes the second switch as well.

  • Patent number: 8149839
    Abstract: Techniques that offer enhanced diversity in the selection of paths (e.g., ECMP paths) and/or ports from ports associated with trunks for forwarding network data traffic. In one embodiment, a network device uses a rotate function to generate a rotated index (path index) that is used to select a path (e.g., an ECMP) path from multiple paths (e.g., multiple ECMP paths) for forwarding a packet. A network device may also generate a rotated index (trunk index) that is used to select an output port from multiple output ports associated with a trunk for forwarding the packet.
