This presentation will describe the effort to construct an effective educational support environment and to develop meaningful educational applications, This system is a framework supporting interactive collaboration which enables both teachers and students to interact in real-time from remote sites. The purpose of this collaboration is to bring interactive multimedia learning in real-time. In order to induce collaborative learning, this paper proposes protocol design process that shares knowledge awareness information for learning environments. The protocol helps learner to mediate and recognize collaborators in the shared knowledge space. We are developing an open-ended collaborative learning support system, which is called prototype system for protocol design, and facilities to share individual knowledge and to learn through collaboration. This system architecture can be viewed as divided in four logical parts: the infrastructure, the service functions, the advanced service functions and the application. The session management is creates/destroys the sessions and performs the functions controlling the QOS by detaching the network load. Session manager include: session control, floor control, media instance control, packet interpreter, event interpreter, media server instance, media interface, network interface private application interface and media server control.
