Abstract (in Japanese) (See Japanese page) 
(in English) Peer-to-Peer file-sharing network is an important part of the Internet, and P2P traffic has been increasing year after year.In particular, the file transfer between peers generates the significant portion of P2P traffic. Therefore, it is important to understand actual status of the traffic characteristics to construct and manage the future networks. We have shown the methodology to identify the file transfer between peers in Winny network in the earlier study. However, the previous methodology is not enough to analyze the unique mechanisms such as the relay file transfers and the overwriting of file-key. In this paper, at first we analyze file-key generation time and TTL(Time To Live) by tracing file-key behavior at the file downloading time point. Secondly, we check the existence of the key by crawling file-key. As a result, we can identify the file uploading peers and file transfers between peers.
