Abstract
It is provided switching means for connecting and disconnecting a link between nodes, so that when a network has a redundant link which forms a loop among nodes—this loop preventing normal connection relationship being maintained—the connection relationship can be made normal by controlling this switching means. Controlling the switching means also achieves rapid recovery from a fault which has occurred in a link between nodes, by utilizing the aforementioned loop to form a route that bypasses the fault.
