TRANSMISSION PATH CONTROL SYSTEM

摘要

A transmission path control system includes a management server and a number of path control device connected to the management server, each path control device is connected to one corresponding router device and located in the same area as that of the corresponding router device. The management server can transmit a virtual lease line (VLL) establishing request comprising information of a start area and an end area of the VLL to one of the path control devices when the management server receives the VLL establishing request from a user, the corresponding path control devices determines which router devices are transmission nodes constituting the VLL according to the start area and the end area, and establishes the VLL by connecting corresponding ports of the router devices determined as the transmission nodes constituting the VLL.
