Abstract

A failure factor can be promptly carved up by effectively prioritizing the ports to which MEPs are assigned in a condition where the maximum number of MEPs is limited. A network monitoring server monitors a network having plural switch devices. The plural switch devices each have a communication confirmation function using transmission and reception of a monitoring frame between ports. An upper limit is set to the number of ports to which maintenance end points (MEPs) are assignable among the respective ports of the plural switch devices. The network monitoring server calculates, for each of the plural switch devices, a monitoring priority corresponding to the probability of failures of a device connected to a network path including the port or the port, and generates data for displaying the calculated monitoring priority of each port in association with each port.
