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.

Dependent claims

A network monitoring server that monitors a network having a plurality of switch devices, in which the plurality of switch devices each have a communication confirmation function using transmission and reception of a monitoring frame between ports, and an upper limit is set to the number of ports to which maintenance end points are assignable among the respective ports of the plurality of switch devices, the network monitoring server comprising:

a processor that executes a program;
a memory that stores the program executed by the processor therein;
and
an interface that is connected to the processor, wherein
the processor calculates, for each of the plurality of 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, and
when the processor calculates the monitoring priority of a given port, the processor enhances the monitoring priority of the given port based on an accumulative operating time of a device connected to the given port or an accumulative operating time of each switch device that exists on a network path between one device connected to the given port and another device connected to the one device.
