- W2357845093 abstract "The QoS assuring is the key component of the VoIP(Voice over IP) system.The traditional VoIP systems are based on the speech codec with a fixed rate,having the problem of packet-loss,especially for continuous packet-loss.The degradation for the speech quality would be seriously caused by this kind of problem.To settle the above problem,the paper presents a new VoIP system which is better in the QoS assuring.The system adopts a formula for the packet-loss-ratio which can more effectively reflect the actual network condition.It adjusts its speed according to the above ratio.Finally,the paper analyzes the performance of the proposed system in QoS assuring of the VoIP system using NS-2.The simulation results show that the proposed system outperforms the previous VoIP systems at the aspect of QoS assuring." @default.
