Abstract:
1. A network load detection system comprising: a test packet transmitting unit transmitting test packets to a to-be-measured communication link at a predetermined first time interval; a burst load transmitting unit transmitting burst loads each including a series of a plurality of load packets to the communication link at a predetermined second time interval different from the first time interval; a delay time measuring 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 determined in accordance with the first and second time periods, and delay time periods corresponding to the elapsed time periods for the respective test packets are measured; a delay distribution generating 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 load calculating unit calculating a network load in accordance with occurrence frequencies in a specific section of the generated delay distributions.
