Abstract :
The classical method of max-min fair-rate allocation doesn´t support the weighted-rate guarantee. The weighted-rate guarantee is necessary to available-bit rate (ABR) service models. This fact has motivated the wide study of weighted max-min (WMM) fair-fate allocation for ABR traffic. However, the combination of close-loop feedback control with the WMM algorithm has not appeared in the previous research. In this paper, a practical WMM fair-rate allocation model is proposed. This scheduling scheme combines and integrates congestion avoidance using proportional control (CAPC) and weighted max-min fair-rate allocation. In the system under analysis, a new weighted traffic scheduler is introduced. This model is designed to achieve higher utilization and also bounded delay for ABR traffic flow control
