<p><P>PROBLEM TO BE SOLVED: To provide an alternative route communication design method by which an alternative communication route for restoring communication within a predetermined restoring time while suppressing communication resources against faults at a plurality of sites on a communication route can be designed. <P>SOLUTION: A communication node selecting means 69 selects a communication node whose time of transferring a fault notifying message is within a predetermined time from among a plurality of fault detection communication nodes for each detecting a plurality of faults on a currently used communication route, and an alternative communication route designing section 70 searches a common alternative communication route for detouring a plurality of faults using the selected communication node when the plurality of faults occur. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
