Abstract
An IP tunnel is constructed between routers connected with the INTERNET. A bandwidth of the IP tunnel is assured by setting up a reservation resource protocol (RSVP) on the IP tunnel. Further as a traffic control of the routers and on the IP tunnel, a frequency for sending packets, which are processed by an input processor and an output processor inside of the router, is allotted based on a ratio of the reserved bandwidth in each IP tunnel, then an algorithm for controlling the traffic is simplified. Furthermore each of the routers on the IP tunnel has a function for scheduling a reservation and manages a time period at which the virtual private network (VPN) of a type of the reservation resource protocol (RSVP) will be used, then it is possible to reserve the assurance of the bandwidth on the designated date and time in the future.
