%X It is important to introduce flow control mechanism into UDP(User Datagram Protocol) based VoIP(Video over IP) in order to guarantee its quality service.To get dynamically adapted to both the coding rate and packetization for VoIP Flows,this paper presented an improved TFRC(TCP-friendly rate control) mechanism to solve the congestion of Network,which provided the rate adjustment based on equation at the end host for the UDP streams to show TCP-friendly.By simulation and analysis,it is suggested that this new mechanism can fairly treat VoIP with small packets and other data flows with large packets,and guarantee QoS of VoIP.
