<P>PROBLEM TO BE SOLVED: To solve the problem that when a communication network composed of GMPLS-unmounted nodes is handled virtually as a single GMPLS node by a GMPLS centralized control unit, the efficiency of fault recovery is deteriorated since the communication network is recognized virtually as a single GMPLS node and then a fault recovery protecting means of GMPLS is actuated by the occurrence of a fault in the virtual node. <P>SOLUTION: When the communication network composed of GMPLS-unmounted nodes is handled virtually as the single GMPLS node by the GMPLS centralized control unit, autonomous fault recovery is performed when the recovery is possible in the communication network composed of the GMPLS-unmounted nodes, but when the fault recovery is not possible in the communication network composed of the GMPLS-unmounted nodes, fault recovery processing by GMPLS is actuated to perform efficient fault recovery. <P>COPYRIGHT: (C)2008,JPO&INPIT |
