PROBLEM TO BE SOLVED: To rapidly recover a fault with respect to a multiplex fault where whole redundant passes become the fault.;SOLUTION: A sender node device NA includes an area advertisement means 12, a redundant pass establishment request means 10A, a detour pass establishment request means 20A, and a fault changeover request means 40A. The detour pass establishment request means 20A requests a detour pass establishing means to establish a fault changeover pass which goes through an area different from the area where the redundant pass goes through as a detour pass, based on identification information of the area where the area advertisement means 12 performs an advertisement. When the fault occurs in the whole redundant passes, the fault changeover request means 40A requests a fault changeover means to changeover the pass to be used for communication from the redundant pass to the detour pass.;COPYRIGHT: (C)2007,JPO&INPIT
