  • Patent number: 9942153
    Abstract: A multiple persistent load balancer system includes a routing sub-network having a plurality of routing sub-network nodes that are coupled to a plurality of load balancer devices. A controller provides a common routing algorithm and a destination distribution list to each of the routing sub-network nodes and the load balancer devices. A first persistent load balancer device receives a first data flow from at least one of the routing sub-network nodes, and uses the common routing algorithm and the destination distribution list to determine whether the first data flow should be redirected to a second persistent load balancer device. If not, the first persistent load balancer device processes the first data flow to retrieve a resource from a server. If so, the first persistent load balancer device forwards the first data flow through at least one of the sub-network nodes to the second persistent load balancer device.

  • Patent number: 9654382
    Abstract: In non-minimal routing, a switch determines outgoing links for preferred paths (e.g. shortest paths). Then, for another node in a preferred path, the switch determines outgoing links for paths to that node in a modified network in which each link in a previously determined path to the node is cut off. Packets can be tunneled on non-preferred paths to that node. Other features and embodiments are also provided.

  • Patent number: 9509602
    Abstract: A LAN includes a CORE switch, some number of TOR switches, each linked to the CORE switch, and each of the TOR switches are linked directly to some number of host devices. Each of the switches in the LAN operate to process and transmit data frames they receive from neighboring LAN devices. Each TOR switch in the LAN builds and maintains a layer-2 forwarding table that is comprised of MAC address information learned from frames they receive from neighboring LAN devices. Selected ports/VLAN s on some or all of the TOR devices are designated to be CORE/switch facing ports (CFP) or host facing ports (HFP). Each of the CFPs are configured to only learn the MAC address in unicast frames it receives and each of the HFPs can be configured to learn the MAC address of both unicast and multicast data frames provided the destination MAC address included in the unicast frame is known.
