SAVQ: stabilized adaptive virtual queue management algorithm

We observe that the desired utilization parameter /spl gamma/ in AVQ algorithm has an influence on the dynamics of queue and link utilization. It is difficult to achieve a fast system response and high link utilization simultaneously using a constant value /spl gamma/. An adaptive setting method for /spl gamma/ is proposed according to the instantaneous queue size and the given reference queue value. This new algorithm, called stabilized AVQ (SAVQ), stabilizes the dynamics of queue maintaining a high link utilization.
