Embodiment Construction
[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0026] figure 1 A flow chart of a large-scale application-oriented software-defined network control optimization method in an embodiment of the present invention is shown;
[0027] The data packet forwarding rule of described method is defined in the TCAM of OpenFlow decision switching equipment and OpenFlow entrance switching equipment; Concrete steps are:
[0028] (1) After analyzing the OpenFlow flow table, the OpenFlow controller divides the decision-making control domain into N decision-making areas, where N is at least 2; each decision-making area includes M OpenFlow decision-making switching devices, and M is at least 2;
[0029] (2) The OpenFlow controller updates the packet forwarding rules in the decision area to the OpenFlow decision switching devices in the deci...
