A model is built up of the joint transmission of the traffic of real-time services and the data traffic admitting a delay. The real-time traffic has the advantage in the occupation and use of the channel resource. It is expressed in terms of a decrease of the data transmission speed to a certain preassigned minimum value. As a free channel resource appears, the data transfer speed increases. The scheme is investigated of the occupation of the channel resource and formal definitions are given of the basic quality indices of the joint service of requests. A solution is considered of the problem for estimating the data traffic volume that can be transmitted together with the traffic of real-time services in the fulfillment of the prescribed restrictions on the delay.
