Abstract
A switching method includes receiving a failure notification through each of two or more paths included in a plurality of paths; by referring to path management information in which a group and a combination of a plurality of predetermined paths are associated with each other for each of a plurality of groups generated by grouping the plurality of paths according to a combination of an initial point and an end point, determining, for each of the plurality of groups, whether a combination of paths through which the failure notification is received matches with the combination of the plurality of predetermined paths; and switching a path included in an object group corresponding to the two or more paths from an active system to a standby system, when it is determined that the combination of the two or more paths matches with the combination of the plurality of predetermined paths.
