摘要： In a service system including client apparatuses for issuing a service request and server apparatuses for receiving a service request and providing service, there is provided a data relaying apparatus for relaying data communication between them. In response to a service request, the data relaying apparatus establishes a connection from the client apparatus to the server apparatus (destination). The data relaying apparatus relays data communication between the client apparatus and the server apparatus by using the established connection. The data relaying apparatus manages a number of connections established to each of the server apparatuses. In response to a service request, the data relaying apparatus accepts or refuses the service request so as to make a number of connections to the server apparatus equal to or less than a predetermined number, and notifies a user refused relaying of a service request that relaying is possible.

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： In order to perform format conversion between the formats of a plurality of files without any work by a user, a file system stores a relation between a conversion originating file and a conversion destination file, and synchronously with an issue of a file operation API, the format conversion processes are executed. A user performs only the tasks essential for an application, without taking into consideration various necessary format conversions (either one-step or multi-step). During the user task, it is not necessary to designate a conversion originating file and a timing of format conversion. A user can use always a latest conversion destination file.
摘要翻译：为了在多个文件的格式之间执行格式转换而不用户进行任何工作，文件系统存储转换始发文件和转换目的地文件之间的关系，并且与文件操作API的问题同步，执行格式转换处理。用户仅执行应用程序所必需的任务，而不考虑各种必需的格式转换（一步或多步）。在用户任务期间，不需要指定转换始发文件和格式转换的时间。用户可以始终使用最新的转换目标文件。
