P2P DATA DELIVERY SYSTEM, P2P DATA DELIVERY METHOD AND P2P DATA DELIVERY PROGRAM

摘要

Since a shared public data delivery module makes a response to a data query to other data delivery modules or other shared public data delivery modules; or to a query from other data delivery modules or other shared public data delivery modules instead of the data delivery module, the data delivery module needs not to directly make response to the data query, and it is hence possible to reduce load imposed on data delivery modules participating in the P2P data delivery system. For example, for a data request issued from a data delivery module, an adjacent shared public data delivery module acquires data substitutionally; it is hence possible to reduce the transfer network amount between the module having issued the data request and other data delivery modules and between the module having issued the data request and other shared public data delivery modules not adjacent thereto.
