NETWORK CONTROLLER DEVICE, NETWORK CONTROL SYSTEM, CONTROL METHOD FOR CONTROLLING COMMUNICATION NETWORK AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/170850
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to make it possible to efficiently allocate a route in which communication quality is assured for each path between end terminals, even when the state of a communication network varies. The present disclosure pertains to a network controller device connected to a communication network for performing data communication between end terminals using a plurality of paths. The network controller device stores log information of a communication state, for each path, collected from the communication network, determines the presence or absence of a path deteriorated in the communication quality on the basis of the log information, determines, when the deteriorated path is present, among routes that can be used by end terminals which use the deteriorated path, whether a path in which the communication quality between the end terminals which use the deteriorated path can be assured is present, calculates, when the assurance is not possible, a new route in which the communication quality between the end terminals which use the deteriorated path can be assured, and switches from the deteriorated path to a path on the new route.
