SDN NETWORK SYSTEM, CONTROLLER DEVICE, AND COMMUNICATIONS TRAFFIC REDUCING METHOD USED IN THEM

摘要

PROBLEM TO BE SOLVED: To provide an SDN network system that is able to reduce communications traffic on a management network.;SOLUTION: A software defined networking (SDN) network system uses SDN to perform flow control for each of a plurality of network devices (31-34) from a controller device. The controller device includes a control part (controller control unit 1) that performs control of an SDN network made up of the plurality of network devices (31-34), and that is installed within a management network (100) in which messages are exchanged by its own format, and a message interchange part (message interchange unit 2) that is installed outside the management network (100), converts a message transmitted by the control part (controller control unit 1) into a standardized message and performs setting to each of the plurality of network devices (31-34).;COPYRIGHT: (C)2014,JPO&INPIT
