<p><P>PROBLEM TO BE SOLVED: To shorten a switch time of a path accompanying a fault occurrence of a transmission path of a redundant signal. <P>SOLUTION: A signal transmitter is provided with: an ingress interface part for determining an output port of an input signal, adding destination information including information on the output port to a signal, and outputting it; two or more egress interface parts; a switch part 40 which is connected to the ingress interface part and the egress interface parts, receives a signal including the destination information, determines a forwarding destination of the signal on the basis of the destination information in the signal, and forwards the signal to at least one of the two or more egress interface parts of a forwarding destination; a notifying part for notifying of alternative destination information including information about an alternative output port when a fault related to the output port occurs; a registration part for receiving the alternative destination information from the notifying part and registering it to a storage part in association with the destination information; and a conversion part 42 for rewriting the destination information in the signal to the alternative destination information when the alternative destination information corresponding to the destination information in the signal input to the switch part 40 is registered to the storage part. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
