System for policy-based network configuration

摘要

In a network-device control system for controlling a network device (N) such as a router (141,142), which is located between a communication terminal (11) employed by a user and a server (12) with which the terminal (11) communicates, at a priority that has been set in advance for the user or for an application, an event notification device (A;17) detects that a user has logged in to the communication terminal (11) or that the user has launched a predetermined application from the communication terminal (11) and reports the user identifier or the application identifier to a network-device controller (B;18). The latter acquires user priority or application priority on the basis of the reported identifier and, in accordance with the priority, controls the router (141,142) on the communication path (CPT) between the communication terminal (11) and the server (12).
