<p><P>PROBLEM TO BE SOLVED: To solve the problem that a correct path route of an L2 layer can not be grasped when a state that a packet does not flow continues for a long period, and for a large-scale network, a load of route retrieval processing is large. <P>SOLUTION: A path route retrieval method includes procedures of: registering configuration information of a network in a server in advance; registering path information specifying a starting node and an end node in the server in advance; registering fault information in the server when a fault is generated; acquiring L2 ring block port information of the network in path route retrieval; using the configuration information to retrieve a path in which neither the fault nor the block port is included by the path information, the fault information, and the L2 ring block port information. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
