摘要： A communication path is set from an ingress node to an egress node on the basis of a specified path setting protocol, and a loopback-test signal is transmitted to the egress node through the communication path so as to perform a loopback-test on the egress node. The ingress node receives a loopback-test response signal transmitted from the egress node on which the loopback-test has been performed, and determines whether or not a loopback-test on the egress node has ended normally by analyzing the received loopback-test response signal.

摘要： A transmission apparatus in a network where a path is set up is disclosed that includes a processing part configured to transmit a frame of the network to an egress node of the path when being set as an ingress node of the path, the frame having setup information of the path written therein, and to loop back the frame when being set as the egress node, the frame having response information written therein based on the setup information read from the frame, the response information indicating that the path is set up correctly.
