  • Patent number: 9876705
    Abstract: A system and method are provided for updating a network including at least one optical circuit switch (OCS) to transition from an existing network topology to a new network topology. One or more intermediate topologies between the existing topology and the new topology are created. Creating the intermediate topologies includes selecting first links to be added to the existing topology without removing links, selecting additional links to be added to the existing topology upon removal of one or more existing links, and adding one or more of the selected first and additional links to the existing topology to create a first intermediate topology. It is determined whether any of the selected first and additional links are still to be added, and if no selected first and additional links are to be added, remaining links are removed. The transition from the existing topology to the first intermediate topology is then effected.

  • Patent number: 9716592
    Abstract: System and methods for efficiently distributing data packets in a multi-path network while maintaining flow affinity are provided. In one aspect, a system and method includes calculating hash values for distributing different flows, or sets of flows, of data packets received at a routing device. The hash value is calculated not only using information in the data packets, but also based on additional information that is determined based on an N-bit derived from the data packets. In some cases, calculating a hash value based on the additional information increases the entropy of the hashing function, thus enabling a routing device to distribute different flows of data packets over a greater number of network paths. Each routing device can derive a different, and randomly generated N-bit key while maintaining flow affinity for each received data packet in a given flow of data packets.

  • Patent number: 9319264
    Abstract: Network performance may be improved by adjusting a logical network topology while avoiding attendant disruptions. By identifying an alternative logical topology, routing network traffic away from links that will be eliminated from the alternative logical topology, and updating a traffic routing plan upon the adoption of the alternative logical topology, a network may adopt a more efficient topology without misdirecting network traffic.

  • Patent number: 9106546
    Abstract: A method and apparatus are provided for communicating congestions that area detected in a communications network. According to the method and apparatus, a first Ethernet frame encapsulating a first PDU is transmitted across an Ethernet network. Congestion in the network is then detected, and an indication of the congestion is inserted in a predetermined header field of the first Ethernet frame. Once the first Ethernet frame is received by an endpoint in the network, the indication of congestion is transferred into a second PDU that is associated with the first PDU. The second PDU is then encapsulated in a second Ethernet frame and transmitted towards the sender of the first PDU.

  • Patent number: 8769148
    Abstract: System and methods for efficiently distributing data packets in a multi-path network having a plurality of equal cost paths each having the same number of hops are provided. In one aspect, a system and method includes reordering the entries in the routing table of one or more peer routing devices, such that succeeding equal cost next hop routing devices that are interconnected in a Clos formation to the peer routing devices received unbiased traffic from each of the peer routing devices, thus enabling the succeeding next hop routing devices to distribute data traffic evenly over additional equal cost multiple hops further into the network.
