Abstract
A device includes: an ingress interface unit determining an output port of an input signal, adding destination information including information on the output port, and outputting the signal; two or more egress interface units; a switch unit receiving the signal including the destination information, determining a forwarding destination of the signal based on the destination information, and forwarding the signal to at least one of the egress interface units as the forwarding destination; a notifying unit notifying of, when a fault related to the output port occurs, alternative destination information including information of an alternative output port; a registration unit registering the alternative destination information in a storage unit in a way that associates the alternative destination information with the destination information; and a translation unit rewriting, when the storage unit is registered with the alternative destination information, the destination information in the signal into the alternative destination information.
