Patent ID: 7145879

Claim:
A network load testing method in which loads are imparted to a network by transfer of data among a plurality of mating apparatuses connected to the network, each apparatus having a transmitting condition and a receiving condition and being selectively controllable to transmit data to a receiver of a mating apparatus and to receive data transmitted thereto by a transmitter of a mating apparatus, the method comprising: transmitting data from an individual one, to a mating one, of said plurality of apparatuses; receiving data in the individual one, transmitted thereto from the mating one, of said plurality of apparatuses; and controlling the data transmitting condition of the individual one of said plurality of apparatuses on the basis of the data receiving condition of that individual apparatus, the controlling further comprising: detecting when the individual apparatus receives a predetermined number of data and, in response to the detecting of when the individual apparatus receives the predetermined number of data, terminating a further transmitting of data remaining to be transferred from the individual apparatus, after stopping the transmission of data transmitting from each apparatus before all the data is transmitted, restarting the transmission data transmitting from each apparatus, counting a reception number of the predetermined number of data in a predetermined period in each apparatus, and determining an abnormality of the network by comparing respective reception numbers counted by the plurality of apparatuses.
