Hierarchical Session Management for Large Scale Sessions
Kyungran Kang, Kilnam Chon · Journal of Electrical Engineering and Information Science · 1998
Modern powerful computers connected by high-speed networks offer the opportunity to build interactive programs supporting collaboration. As result, the scale of such collaboration will increase dramatically like hundreds and thousands. Existing systems for multiparty sessions does not consider such a large number of participants. Centralized system will have the central management object overloaded with membership control functions and floor control functions. Distributed system will have the participants confused with uncontrolled manner of interactions. This paper suggests a way to lessen the load of the session manager by introducing hierarchical session structure. The participants are divided into multiple groups and each group has its own manager. The members' floor control requests are processed by its group manager. The group managers interact with the session manager to coordinate the interactions among the whole participants based on the session control policies. This paper describes the management components and the way to carry out the session management functions. The proposed approach will be compared with other large scale session approaches.
