<p>PROBLEM TO BE SOLVED: To provide a route calculation method to improve traffic distribution and improve efficiency of network use further at the same time to suppress calculation volume for re-calculation of routes when the routes are changed for traffic distribution or re-routing caused by a trouble. SOLUTION: The route control method uses the first calculation stage which calculates a plurality of routes from the sending and receiving equipment of a sending source to the sending and receiving equipment of a receiving destination based on cost assigned beforehand to the frame sending and receiving equipment 3 and 4, the frame relay equipment 5 and 6, and the links, and the second route calculation stage which obtains a route possible to reserve using the bandwidth information to be reserved by the bandwidth traffic and the bandwidth information already reserved.</p> |
