Hierarchical Multicast Address Management and Connection Control
Jia Wang · 1999
Multicast address management and connection control are two essential components needing to be solved in the multipoint applications. Based on hierarchical autonomous structure in accordance with theself-organization topologies of INTERNET, a multicast address management scheme which sets up the hierar-chical partition is put forward in this paper. which is dynamic, of Multicast address space in order to reduce the blocking probability. A connection control hierarchy (CCH) based on master/slave relationship and a simple efficient building algorithm of multi-point connection are also advanced. The normal operations of multicast address management and multi-point connections controller are also described. With simulation experiment,three of multicast address allocation modes, hierarchical autonomous mode (HAM), central mode (CM) and network-divided mode (NDM), are compared. The result shows that the hierarchical autonomous mode inte-grates the merits cf central mode (CM) and network-divided mode (NDM), owns high efficiency in the whole.Connection control hierarchy (CCM) is also efficient in the connection control. They are shown to be highly robust, flexible and scalable.
