Abstract
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.
