摘要： When a client-server system that adopts a Web service featuring dynamic connection among different systems is constructed, an existing priority control device therein disconnects communication with lower priority, at the time of server overload that continues for several hours. Thus, the availability of the system is reduced. A client-server Web service system includes a unit for interpreting communication protocols at a protocol layer 4 used in the system, a unit for receiving requests transmitted from clients to a server, for buffering, a unit for analyzing the protocol type, the destination, and the communication contents of each of the requests, a unit for converting the result of the analysis into a priority, and a unit for transmitting the buffered requests to the server based on the priority and then transmitting to the clients responses from the server.

摘要： A congestion control system provided in a connection portion between a network for an Internet provider and the Internet estimates a processing capability of a Web server on the basis of states of TCP/IP such as a window size of connection being connected, a cancellation rate of packet, a response time, a throughput and the like in a congestion state of the Web server to be requested and a network to the Web server and calculates a regulation duration for each Web server on the basis of the processing capability and the number of clients being in a waiting state for a re-request to the Web server so that the client is regulated when a response for regulating the re-request with the regulation duration is returned to the client. Consequently, since the number of re-requests per unit time can be made fixed, congestion due to re-requests can be prevented and the user can necessarily utilize the Web server upon re-request. Further, the service utilizable hour can be grasped to utilize the Web service deliberately.
