METHOD FOR MEASURING P2P NETWORK USAGE, RECORDING MEDIUM, DEVICE AND SYSTEM FOR PERFORMING THE METHOD

摘要

A method for measuring p2p network usage includes: an uploader obtaining proof of provenance from a manager; when the downloader's file transfer order is completed, starting a p2p communication session through a handshake between the downloader and the uploader; transmitting, by the uploader, the file of the ordered file transfer unit (piece) to the downloader when receiving the ordered file transfer unit (piece) from the downloader; transmitting, by the uploader, the file transfer receipt to the manager when receiving a file transfer receipt and a piece received ACK from the downloader; and receiving a file transfer fee from the manager based on the file transfer receipt when the download of the file is completed. Accordingly, it is possible to provide a highly reliable content charging policy among users of the p2p file transfer network.
