Paper Abstract

In this paper, we propose the dynamic priority control mechanism for handling the cell service ratio according to the relative cell occupancy ratio in the buffer in order to improve the QoS. We also analyze theoretically the QoS, that is the cell loss probability and the mean cell delay time for the proposed priority control mechanism. The two service classes of our concern are the delay sensitive class and the loss sensitive class. The relative cell occupancy ratio represents the ratio of the number of the loss sensitive class cells to the number of the delay sensitive class cells stored in the buffer. In other words, the proposed priority control mechanism has the methods to change dynamically the cell service ratio according to the relative cell occupancy ratio of the loss sensitive class and the delay sensitive class. Here what the cell service ratio is K means that a loss sensitive class cell is served whenever the maximum number K of delay sensitive class cells are consecutively served. The analytical results show that the proposed control mechanism is capable of improving the cell loss probability with regard to loss sensitive class cells and the mean cell delay time with regard to delay sensitive class cells by selecting properly the cell service ratio according to the relative cell occupancy ration in the buffer and the input traffic conditions.
