A method is proposed for estimating the capacity of internal buffer memory of the router for networks with priority-based traffic control. The traffic with arbitrary distribution of lengths of packets of different classes is considered. Priority queueing management is based on a discipline with mixed priorities. A formula is derived for the capacity of the router buffer memory required to store packets of each class for a given probability of buffer overflow. The account of the dependence of required buffer memory capacity on the type of distribution of packet lengths is shown to be necessary to ensure quality of service for short-term bursts in traffic speed and to prevent packet loss.
