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.

Abstract: Disclosed is a method for processing a service function chain request, which includes: classifying the service function chain request received; determining a domain to process the service function chain request; wherein the service function chain requested by the service function chain request includes at least one virtual network function (VNF); distributing the service function chain request to the domain determined; determining at least one server for implementing the at least one VNF; and determining the time at which the at least one server implements the at least one VNF. The disclosure also discloses a system for processing a service function chain request.
