  • System and methods for optical lambda flow steering
    Patent number: 9520961
    Abstract: A system implementing an optical steering domain that steers traffic flows through a plurality of processing nodes is described. The system includes a first, second, and third wavelength selective switch (WSS). The first WSS receives the traffic flows, and transmits traffic flows out a plurality of tributary ports toward the processing nodes. The second WSS receives the processed traffic from the processing nodes, and sends it to a third WSS. The third WSS receives the processed traffic from the second WSS, and causes the processed traffic requiring further processing to be transmitted out its third plurality of tributary ports to be looped back toward the plurality of processing nodes, and causes the processed traffic that does not require further processing to be transmitted by a different tributary port of the third WSS that is an exit port leading out of the optical steering domain.

  • Pay-as-you-grow gradual cutover method to scale a provider bridge network to a VPLS or provider backbone bridging network
    Patent number: 8730956
    Abstract: A method and apparatus that operates two bridging protocols in a hybrid bridging node is described. The operation of the two bridging protocols in the hybrid node allows for an incremental transition of a provider bridging network from operating a legacy bridging protocol that shares MAC addresses to a bridging network that operates VPLS and/or PBB bridging protocols. The hybrid bridging node selectively broadcasts unicast packets with unknown MAC addresses from the nodes operating VPLS and/or PBB to nodes operating a legacy bridging protocol.
