Abstract
An input/output switching apparatus which can construct the system more flexibly as compared with the conventional system. The input/output switching apparatus is configured so that a user can manage the connection state of a physically-existing switching unit as the connection state of a virtual switching unit which corresponds to the physically-existing switching unit. Thus, the user can control the physical switching unit merely by operating the virtual switching unit which is constructed so as to be convenient for operation.
