摘要：<p>PROBLEM TO BE SOLVED: To locate a failure on a communication path passing through a plurality of networks in a shorter time. SOLUTION: The method for managing a communication path comprises step S1 where a network management system 11 confirms communication conductivity with a network unit 33, steps S3(1)-S3(3) for specifying a network having a failed network management system 11 when communication is nonconductive, step S4 where location of failure in other network 2 specified to have a failed network management system 11 is requested for a network management system 21 of the network 2, and step S5 where the network management system 21 executes location of failure in the network 2.</p>
