Title:
ROUTE CONTROL METHOD AND ROUTE SETTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/026684
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a route control method and a route setting device capable of predicting and avoiding a congested section in real time that accidentally occurs, without needing an existing route control technique such as OSPF. [Solution] The route control method and the route setting device according to the present invention are configured such that a learner is prepared for each path, a functional type of the learner for the path is adjusted by using, as training data, traffic information (such as arrival rate of packet and queue length) and congestion information on the path during packet transfer (whether the path is congested or not), and when the path is congested, the path is switched to a path corresponding to output from a learner indicating that there is no congestion. The learner optimizes the functional type in this manner, and hence even when a path is accidentally congested, the path can be immediately switched to an alternative path.
