Effect of TCP and UDP parameters on the quality of video streaming delivery over the Internet

Delivering real-time video over the Internet is an important issue for many Internet multimedia applications. Transmission of real-time video has bandwidth, delay, and loss requirements. The application-level quality for video streaming relies on continuous playback, which means that neither buffer underflow nor buffer overflow should occur. Since the Best Effort network such as the Internet does not provide any Quality of Service (QoS) guarantees to video transmission over the Internet. Thus, mapping the application-level QoS requirements into network-level requirements, namely, limited delay jitters. End-to-end application level QoS has to be achieved through adaptation. Since the QoS of video streams over IP networks depends on several factors such as video transmission rate, packet loss rate, and end-to-end transmission delay. The objectives of this paper are to simulate an adaptation scheme to include the effect of User Datagram Protocol (UDP) parameters on delay jitter and datagram loss values to increase the efficiency of UDP protocol to prevent the network congestion and increase the adaptivity and also, simulate an adaptation scheme to include the effect of Transmission Control Protocol (TCP) parameters on the transmission rates to increase the adaptivity of the transmission.
