Abstract
In a packet transport network, to determine a path route in which a bottleneck does not occur with a small amount of calculation, provided is a network system, including data transfer devices and a management computer, each of the data transfer devices including IFs, in which the management computer is configured to: store remaining bandwidth information on the each of the IFs; select one of bandwidths; judge, based on the remaining bandwidth information and the selected bandwidth, whether or not the each of the IFs is usable; determine a route candidate though which data is transferred, bypassing the each of the IFs which has been judged to be unusable; judge, based on the remaining bandwidth information, whether or not continuity of the IF through which the route candidate passes is possible; and allocate the route candidate, the continuity of which is possible, to a new path.
