To realize a network quality evaluation equipment capable of importing certainly a maximal and minimal values to enable high-accuracy measurement when importing measured data of an arithmetic processing unit by a display unit operating asynchronously with the arithmetic processing unit.
The network quality evaluation equipment includes the arithmetic processing unit that executes a statistical arithmetic processing for measuring communication quality at a predetermined cycle based on packets extracted from a communication network to thereby update the measured data, and the display unit that operates asynchronously with the arithmetic processing unit and retrieves the measured data at a cycle shorter than a measured data updating cycle from the arithmetic processing unit to display the data in a desired form.
