摘要： A relaying method includes a request packet generation operation generates a request packet for requesting a connectivity check for all communication routes between said receiver and said transmitter, a request packet transmission operation transmits a generated request packet to a relay, a route information addition operation adds information representing the router itself to the received request packet as route information, a request packet forwarding operation forwards the request packet to which said route information has been added to each of all the communication routes between said receiver and said relay, a response packet generation operation has been transcribed, a response packet transmission operation in which said receiver transmits the generated response packet to said transmitter via said relay, a response packet forwarding operation forwards the received response packet to said transmitter, and a route information output operation outputs the route information included in the received response packet.

摘要： A path switching system can dramatically decrease time required until a transfer path of user data is switched to a detour path when a failure occurred to a system/line constituting the network. In the path switching system, a path is set by a switch device and a plurality of relay devices adjacent to the switch device, and the switch device has a notification processing section notifying information to specify a corresponding relay device to the plurality of other relay devices when a failure of an adjacent relay device or a line failure between adjacent relay devices is detected, and the relay device has a path change processing section canceling information on the path that passes through the relay device detected to have a failure, from the information notified by the notification processing section of the relay device.
