PROBLEM TO BE SOLVED: To provide a method of measuring a network response time and a network transport factor so as to locate a degradation causing spot in a network system failure analysis support method. SOLUTION: In a network of connecting a plurality of clients and a plurality of servers, a response time and/or a transport factor in a path from a branch line to a counter branch line is measured, a spot which causes degradation in the response time/transport factor is automatically obtained by the comparison of a plurality of pieces of path information, operation information is collected from a network instrument located at the degradation causing spot, it is determined on the basis of the operation information whether degradation in the response time/transport factor is induced by a lack of the performance of the network instrument or a line bandwidth, the interface of the network instrument on a degraded path is blocked, and communication is detoured to another path where no degradation is detected.
