ABSTRACT:
A system includes a unit transmitting test packets to a to-be-measured communication link at a first time interval, a unit transmitting burst loads each including a series of load packets to the communication link at a second time interval, a unit performing measurement of delay time periods in a manner that a plurality of test packets transmitted by varying elapsed time periods each from an instance of transmission of the burst load to an instance of transmission of the test packet are received from the communication link in a fluctuating time interval, a unit generating delay distributions indicative of packet occurrence frequencies in relation to a delay time period of the communication link in accordance with the measured delay time periods, and a unit calculating a network load in accordance with occurrence frequencies in a specific section of the generated delay distributions.
