Implementation and evaluation of the P2P-Web system

Peer-to-peer (P2P) services, such as Gnutella, Groove [http:www.clip2.com/GnutellaProtocol04.pdf], and Freenet [http://freenet.sourceforge.com], have become popular for sharing files, information, and contents. For ordinary users, however, it can be difficult to utilize P2P-software, because need to install the software, set parameters, and share information. We thus proposed a P2P service model, that only requires user terminals to have a Web browser, and we previously described the key technologies for developing P2P-Web collaboration, including the software architecture, agent functions, and applications [S.Kimura et al., June 2002]. We have since implemented a P2P-Web system to enable collaboration among databases. In this paper, we describe the system architecture and evaluate the performance and usability of the system through an experiment.
