Abstract :
This paper describes the design of the whole framework of a VoIP Client System. In this design, we use the design idea of automaton to build the entire dialing and hang up processes, use multithread to implement event synchronous mechanism. Then we use a strategy to couple the Jitter-Buffer design with the automatic adjustment of the redundant packets. This strategy gets a good trade-off at the client between the methods of solving delay and those of solving dithering. The experiment result indicates that this framework keeps good QoS performance even in bad network conditions.
