A Clustering Model of the Application-Level Multicast
This chapter reviews the most important fact of the application-level multicast (ALM) and then describes a novel concept of modeling relative density of members called bunched mode and a proposed host-end multicast routing protocol called shortest tunnel first(STF). The bunched mode is based on the thematic multicast concept (TMC), which means that it is atypical multicast scenario where there are a lot of interested hosts in certain institutions, relatively far from each other. This situation is called bunched mode, in which the members of a multicast group are locally in the dense mode, and globally their situation is similar to the sparse mode because these spots are far from each other. The developed analysis tool, Net Sim, and the implementation of the TMC, Pardede CAST, are also presented as the tools of this research.
