摘要： A system high in availability which includes plural file servers and local disks is realized. A distributed file system has plural file server clusters that perform any one of file storage, file read, and file deletion according to a request. A gateway device mediates requests between a client device that transmits a request including any one of file storage, file read, and file deletion, and the distributed file system. The gateway device includes a health check function unit that monitors an operating status of the file server cluster, and a data control function unit that receives the request for the distributed file system from the client device, and selects one or more of the file server clusters that are normally in operation, and distributes the request to the selected file server clusters.

摘要： When a plurality of services are enjoyed by a single terminal, a communication regulation caused by another service has influence on enjoyment of another service. A service provider and a mobile communication provider are affiliated with each other and newly provide an affiliated service in which a communication fee for a service use is borne by the service provider to a user. Conventional communication and affiliated service communication are performed on a single communication line of the user together, and communication control is performed in units of services such that a service quality of the affiliated service is maintained. It is implemented by affiliating a communication log and contract information between business operators and performing communication identification using user information at the time of a contract as a key.

摘要： A load balancing system for performing stable processing and high reliability includes a management device which acquires time information indicating the time required in past processing on each of n processing devices, estimates a required time required for each processing devices to process processing target information based on the time information thereby obtaining an estimated time, and transmits estimated time information indicating a relationship between the estimated time and the processing device to a load balancing device. The load balancing device determines m (1

摘要： In a gateway device holding a traffic relay function, the storage cost and the retrieval time for a great amount of access logs are prevented from increasing. The gateway device includes a traffic relay function, a protocol analysis function, a log output function and a log retrieval function. These functions output an access log in compressed or uncompressed form in compliance with a rule for each protocol designated by the manager in accordance with the degree of importance. The retrieval is carried out for the uncompressed file.
