ABSTRACT:
A protocol converting unit stores identification information for identifying a transfer path for data in a second network and a transmission source address specified in a packet in a corresponding manner. A failure detecting unit detects a transfer path in which a failure has occurred in the second network. A dummy-packet transmitting unit obtains a transmission source address corresponding to identification information of the transfer path in which the failure is detected, and transmits a dummy packet in which the obtained transmission source address is specified as the transmission source address to a first network.
