Publication Abstract

Quality of Service (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. There are three main obstacles in video
streaming over the Internet. The first is the variable network performance due to load changes. The second, the
bandwidth availability is highly unpredictable which makes quality adaptation difficult. Finally, network
congestion, manifests itself by low arrival rate and packet losses. The last paper simulated an adaptation scheme to
include the selection of the transmission rates higher and lower than the default transmission rate to increase the
adaptivity. The objective of this paper is to simulate an adaptation scheme to include the effect of UDP parameters
on delay jitter and datagram loss values to increase the efficiency of the UDP protocol and prevent the network
congestion to increase the adaptivity.
