  • Patent number: 10785265
    Abstract: Disclosed is a method and device for target sequence identification, wherein an optical binary sequence and an all-zero sequence are subjected to an XNOR operation and a first candidate sequence set is generated by splitting the result sequence; a second candidate sequence set is generated by splitting the optical binary sequence; multiple binary sequences are selected from the first candidate sequence set and the second candidate sequence set according to the target sequence to generate a to-be-delayed sequence set; various delay duration are configured for each binary sequence of the to-be-delayed sequence set; a to-be-matched sequence set is generated after delaying; an AND operation is performed on the sequences of the to-be-matched sequence set to generate a final sequence; and the number and position of the target sequence in the binary sequence can be determined according to the number and position of a pulse in the final sequence.

  • Publication number: 20150295654
    Abstract: The present invention discloses a system architecture for global optimization of a flexible grid optical network and a global optimization method therefor. The system architecture for global optimization of the flexible grid optical network provided in the present invention comprises a requesting unit for global optimization and an execution unit for global optimization, wherein the requesting unit for global optimization generates a request message for global optimization, and sends the request message for global optimization to the execution unit for global optimization; and the execution unit for global optimization parses the request message for global optimization, performs global optimization based on a constraint condition for global optimization, a computation algorithm for global optimization and a network topology and resource information of the flexible grid optical network, and returns a global optimization result to the requesting unit for global optimization.

  • Patent number: 8565071
    Abstract: A protection method in a packet transport network is provided. A protection path is established for a service data flow borne on a shared protection ring in the method, where the protection path includes a wrapping protection path and a steering protection path. Firstly, a first service data flow is sent through the wrapping protection path. Then, a service data flow node stops sending a second service data flow subsequent to the first service data flow to the wrapping protection path, and buffers the second service data flow. When the first service data flow completely passes by the service data flow node again, the buffered second service data flow is switched from the wrapping protection path to the steering protection path.
