NETWORK MANAGEMENT METHOD, NETWORK SYSTEM, INTENSIVE ANALYSIS DEVICE, TERMINAL DEVICE, AND PROGRAM

摘要

The present invention enables appropriate narrowing down to a suspected portion and enables efficiency of a fault analysis work, on the occasion of a network fault analysis. This intensive analysis device receives, from one or more terminal devices connected to a network, route information that is about routes from the respective terminal devices to a destination node and that has been obtained by the respective terminal devices, and isolates a suspected fault portion of the network from the route information using a learning model.
