Stream video traffic control algorithms

Algorithms for controlling stream video traffic are considered. The features of video codec traffic, which has a pronounced packet character, are analyzed. The characteristics of such flows and their influence on the size of queues and delays in telecommunication network nodes are investigated. A generalized Khinchin-Pollachek formula is given and linear dependence of the formula numerator on the load factor is shown. The main causes of packet delays in the queues of a telecommunication network are considered and the influence of these delays on the processes of controlling stream video traffic is shown. A video stream control algorithm is proposed based on size measurements of the buffer memory in the client’s equipment. It is shown that such an algorithm eliminates the influence of delays from the feedback loop of the control system. The results of simulation modeling of the considered processes are presented.
