  • Scalable network virtualization with aggregate endpoints
    Patent number: 9596099
    Abstract: Techniques provided herein use aggregate endpoints in a virtual overlay network. In general, aggregate endpoints operate as a single receiving entity for certain packets/frames sent between different physical proximities of the virtual overlay network.
    Type: Grant
    Filed: May 6, 2015
    Date of Patent: March 14, 2017
    Assignee: Cisco Technology, Inc.

  • TRILL optimal forwarding and traffic engineered multipathing in cloud switching
    Patent number: 8717944
    Abstract: In one embodiment, a plurality of leaf switches that include host facing ports are configured as a cloud switch. An indication of connectivity between the leaf switches of the cloud switch and routing bridges (RBridges) external to the cloud switch may be added to link state packets (LSPs) sent over the at least one logical shared media link. A lookup table may be generated that specifies next hop leaf switches. The generated lookup table may be used to forward frames to one or more particular nexthop leaf switches. Further, traffic engineering parameters may be collected. Equal cost multipath (ECMP) nexthop leaf switches and distribution trees to reach one or more destinations may be examined. Traffic may be distributed across ones of them based on the traffic engineering parameters.
