| The primary researching of this thesis is the realization of the communicating function of the multimedia meeting system based on IP in existence, and the design of the multimedia meeting system is presented. On the bone network level, the configuration of the router is presented. On the join level of the network, the join resolution is presented. The emphasized part of the thesis is the design of the subsystem of the communicating control, in this thesis, the kernel of communicating control is designed by a routing protocol which can support the function of IP multicast; In the design of the software simulation of the IP multicast, the analyzing mode of the software is provided through the method of the Object Oriented Analyzing, and the UML description is provided at the same time. The IP multicasting still has some deficiency in the practice and the theoretic, some exploration of those question are presented, too. |
