Patent ID: 8629907

Claim:
A data acquisition system for collecting data over a network, from data generator devices at a plurality of respective data generating points, into a data utilization device at a data utilization point, comprising at least: a plurality of transmit-side transmission control devices, each including a CPU, on the data generating point side of the network for sending data generated by the data generator devices to the data utilization point side; and a receive-side transmission control device, including a CPU, on the data utilization point side for aggregating the data from the plurality of transmit-side transmission control devices, and sending the data to the data utilization device, wherein the transmit-side transmission control device receives notification of an allowable data transmission quantity from the receive-side transmission control device, retains that allowable data transmission quantity, adjusts the data quantity sent from the data generator device so as to fit within that allowable data transmission quantity range, generates a request to change the allowable transmission data quantity based on a transfer need request from a data generator device among the data generating points, and sends the request to change the allowable transmission data quantity to the receive-side transmission control device, wherein the receive-side transmission control device retains the respective allowable data transmission quantities for the plurality of transmit-side transmission control devices, upon receiving the request to change the allowable transmission data quantity, reallocates the allowable data transmission quantities among the transmit-side transmission control devices to fit within the data processing load range within the data utilization point, and notifies the corresponding transmit-side transmission control devices of the reallocated allowable data transmission quantities.
