Title:
TRANSFER APPARATUS, ADJUSTMENT APPARATUS, AND PARAMETER ADJUSTMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2017/199301
Kind Code:
A1
Abstract:
A transfer apparatus according to the present invention is a switch apparatus (10) forming a network and comprises: a link state database (11) in which topology information of the network, and a priority of the subject apparatus and a priority of another transfer apparatus forming the network are held, the priorities being used for path calculations; a shortest-path calculation unit (121) that, on the basis of the topology information, calculates a shortest path from a first switch apparatus to a second switch apparatus among the transfer apparatuses forming the network; and a priority adjustment unit (13) that adjusts the priority of the subject apparatus on the basis of the shortest path calculated by the shortest-path calculation unit (121) and the priorities of the subject apparatus and the other transfer apparatus. The priority adjustment unit (13) so adjusts the priority of the subject apparatus as to reduce the number of duplications between the priority of the subject apparatus and the priority of another transfer apparatus which configures, together with the subject apparatus, a shortest path from the same start point to the same destination, and of which the distance from the same start point is the same as the subject apparatus.
