摘要
Multicast capability, including multicast address and multicast rout- ing mechanisms, at the network layer is necessary in order to reduce the band- width requirements of multiparty, multicast applications. Based on hierarchical au- tonomous structure in accordance with the self-organization topologies of Internet, the paper puts forward a multicast address management scheme that is shown to be robust and scalable. Connection control hierarchy (CCH) based on master/slave re- lationship and a simple efficient building algorithm of multi-point connection is also built. The paper also describes the normal operations of multicast address manage- ment and multi-point connection controller. Through simulation experiment, HAM, CM and DDM of Multicast Address Allocation are compared. HAM integrates the merits of CM and DDM, which is efficient as a whole, robust and scalable. CCH raises the efficiency of connection control, and is highly robust, flexible and scalable.
