Abstract:
1. A path pair designing method for creating a path pair made up of two disjoint communication paths that each passes through plural nodes and links in a network and does not pass through a same node or a same link in the network, said path pair designing method comprising: storing information about the plural nodes and links in a server; producing, in the server, a specified function for selecting an optimized said path pair; producing, in the server, a first condition that requires that said path pair is made up of two of the communication paths; producing, in the server, a second condition that requires that each of said two communication paths is in a disjoint state; simultaneously selecting, in the server, said two communication paths by using the stored information and the specified function constrained by the first and second conditions; and creating said optimized pair path made up of the two simultaneously selected communication paths.
