Abstract: <P>PROBLEM TO BE SOLVED: To achieve fault notification on a multipoint logical path and switching of logical paths, when the multipoint logical path is constituted by using a transfer protocol constituting a logical path represented by an MPLS or the like in a ring network.  <P>SOLUTION: Multipoint logical paths for not only transmitting a frame transmitted from a transmission terminal node to a multicast frame receiving terminal node, but also for transferring the frame up to a transmitting terminal node by circulating a ring so as to terminate the frame also in the transmission terminal node are prepared in advance for two routers of an active system and a stand-by system. A node which detects a fault transmits a forward fault notification frame, to the multicast logic path where the fault has occurred. The transmission terminal node, receiving the forward fault notification frame, stops the use of the received multicast logical path and transmits the frame by a path which has yet to be received the forward fault notification frame. When the forward fault notification frame is received from both of the multicast logical paths, the transmission terminal node copies the frame and transfers the copied frame to both the multicast logical paths.  <P>COPYRIGHT: (C)2009,JPO&INPIT
