DISTRIBUTION SYSTEM AND SERVICE TRANSMISSION/RECEPTION ENVIRONMENT FORMATION METHOD

摘要

There is provided a service transmission/reception environment which flexibly shares resources only via a resource group valid for service provision among resource groups dynamically found and satisfies a requested condition. A service formation processing (232) transmits a request service condition (214) and searches resources described in a service list (212) of each device and calculation resources of each device so as to judge the valid service level. Here, the search range can be limited according to a resource disclosure policy (217). In the service formation processing (232) of each device, data to be disclosed to another device is limited. A service session management processing (233) discloses each resource according to the service provided by using the disclosure mode of each resource stored in a mode management table (215).
