Abstract
Several peer-to-peer solutions have been newly suggested in recent years to resolve the problems in the existing P2P architecture such as Soribada and Napster as well as the client/server architecture. We design a content-sharing application based on the JXTA that is a P2P solution of the Sun Microsystems. It is for a community activity and has seven modules to share several kinds of contents with peers such as file, web-contents, picture, video and real-time video as well as for chatting and group management. And, we are developing to share the 3D streaming as well as 3D avatars. Peers on this application can make groups to easily share their own contents. We have proven it is scalable with simulation results.
