PROBLEM TO BE SOLVED: To appropriately perform request regulation of a system comprising a plurality of signal processing servers and a plurality of data processing servers.SOLUTION: A congestion determination device 50 in a system instructs a signal processing unit 200 to perform request regulation when congestion is detected in a data processing server. The congestion determination device 50 terminates the request regulation when a request number condition sufficiency notification with regard to a regulation target request number in the signal processing server of the signal processing unit 200 is received after the request regulation is started and a resource usage rate in the data processing server becomes lower than a prescribed threshold. A representative server of the signal processing unit 200 estimates a regulation target request number for the whole signal processing unit 200 on the basis of the regulation target request number received in the own server, estimates a data request number for the whole data processing server from the estimated value and transmits the request number condition sufficiency notification to the congestion determination device 50 when the estimated value is less than a prescribed threshold C. |
