TRANSMISSION PATH QUALITY MEASURING DEVICE, COMMUNICATION SYSTEM, QUALITY MEASUREMENT METHOD, AND QUALITY MEASURING PROGRAM

摘要

The present invention provides a communication quality measuring device, a communication quality measurement method, and a communication quality measuring program by which the reliability and accuracy of the results of measurement carried out on a transmission path are improved, and comparisons between the results of measurement at one time and the results of measurement at another time or between one flow and another flow are made easier.;The communication quality measuring device includes: a quality measuring unit (734) that measures the communication quality of a transmission path, based on data being transmitted through the transmission path; an observation time calculating unit (738) that calculates a time interval for securing an observation time for the quality measuring unit (734); and a measurement triggering unit (736) that causes the quality measuring unit (734) to start measurement at the time interval calculated by the observation time calculating unit (738). The observation time is the time required for maintaining predetermined measurement accuracy in the communication quality measured by the quality measuring unit (734). The data are the data to be transmitted for test to the transmission path, for example.
