A congestion control system includes: edge devices that aggregate service request messages from clients, and distribute the messages to servers; a plurality of servers that process the service requests from the clients; and a control device. The control device: acquires a service request occurrence rate observed from the edge devices, and, on the basis of the acquired occurrence rate, determines the proportion of service request messages to be regulated as a regulation rate; determines the number of servers that should be operating, and notifies the edge devices of the regulation rate that was determined; and, on the basis of the number of servers that was determined, puts new servers into operation or stops the service of currently operating servers. In a system in which there a limit to server expansion and there is potential for congestion collapse to occur, integrated control is conducted in such a manner that revenue, which allows for input regulation in edge devices and server expansion, is maximized. |

1. A congestion control method performed by a controller connected to an edge device and a plurality of servers through a network, the edge device aggregating service request messages from clients and allocating the service request messages to servers, the plurality of servers serving service requests from the clients, the congestion control method comprising:
a step of acquiring a service request occurrence rate observed by the edge device; a step of ,on the basis of the occurrence rate, determining a ratio of service request messages to be regulated as a regulation rate and determining the number of servers to be operated; and a control step of notifying the regulation rate of the edge device and putting a new server into operation or stopping an operating server on the basis of the number of the servers to be operated. |
