Abstract
When a network system of the present invention performs a bandwidth-guaranteed communication, a terminal device collects information on one or more relay devices on a path to another terminal device via a bandwidth request packet transmitted to the another terminal. When the bandwidth cannot be allocated, a detour path is searched according to the collected relay device information so as to perform the bandwidth-guaranteed communication via the detour path.
