An aspect of the present invention provides an input/output switch including: a plurality of virtual switches formed by asymmetrically divided switches with symmetrically aligned ports; and ports on a side of end points and ports on a side of an intermediate switch allocated for each of the virtual switches, in which some of the ports of the virtual switches on the side of the end points act as ports that form a path that returns traffic among the virtual switches.
