摘要

PROBLEM TO BE SOLVED: To specify a connection interruption place in a network.;SOLUTION: The transmitting side and receiving side nodes 2 and 5 transmit a CCM frame to partner nodes 5 and 2 respectively, in a predetermined period. Then, for example, if a line between relay nodes 3 and 4 is interrupted, the nodes 2 and 5 do not receive the CCM frame from the partner nodes to detect the occurrence of an LOC (Loss Of Continuity). Then, the nodes 2 and 5 send an LTM frame to the partner nodes, wait for an LTR frame to be returned, and transmit the MAC address of a transmission source of the LTR frame returned in the end to the partner nodes. After that, the nodes 2 and 5 subsequently determines that connection interruption occurs between a node of the MAC address sent from the partner nodes and a node returning the last LTR frame.;COPYRIGHT: (C)2011,JPO&INPIT
