Provided are a line card determination, determination processing method and device, and line card determination system, the determination method comprising: receiving a flow table entry and/or a group table entry comprising a port number and issued by a controller, the port number being a port number of a service flow corresponding to the flow table entry and/or the group table entry; and according to a pre-stored corresponding relationship between line cards and the port numbers of each line card in a data forwarding device, determining the line cards corresponding to the port numbers. The technical solution of the present invention addresses the problem in the related technology of the waste of communication resources and line card resources caused by a main control panel being unable to determine to which specific line card the flow table entry or the group table entry issued by the controller should be issued, such that as a result the flow table entry or the group table entry can only be issued to the related line card via a simple mapping; thus, the invention greatly reduces the waste of communication resources and line card resources. |
