P2P DATA DISTRIBUTION SYSTEM, P2P DATA DISTRIBUTION METHOD, AND P2P DATA DISTRIBUTION PROGRAM

摘要

It is possible to provide a P2P data distribution system, a P2P data distribution method, and a P2P data distribution program which reduce the processing load of a data distribution device and traffic of a network. Instead of the data distribution device, a common public data distribution device performs data inquiry to other data distribution device or a common public data distribution device and response to an inquiry from other data distribution device or the common public data distribution device. Accordingly, the data distribution device need not response directly to a data inquiry. Thus, it is possible to reduce the load of data distribution devices participating in the P2P data distribution system. For example, for a data request made by a data distribution device, an adjacent common public data distribution device acquires data by proxy, which reduces the transfer network amount between the data distribution device which has made the data request and another data distribution device and between the data distribution device which has made the data request and not adjacent other common public data distribution device.
