OPEN FLOW SWITCH, OPEN FLOW CONTROLLER AND OPEN FLOW NETWORK SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an open flow network system capable of stabilizing the throughput of the open flow network without user consciousness.;SOLUTION: An open flow switch is configured to be applicable for optimization of one or a plurality of types of WANs. An open flow controller, when calculating a communication route in regard to a new flow, obtains a propagation delay time in the communication route, and according to the propagation delay time, determines whether or not WAN optimization is to be applied to a packet in the flow and a type in the case of application, and notifies a predetermined open flow switch in the communication route of that effect.;COPYRIGHT: (C)2014,JPO&INPIT
