Two goals evaluating flow control are presented , and several current flow control schemes are also analyzed. This paper combines the NAK based flow control with the pruning algorithm, and gives a time difference based pruning scheme.

• 明确阐述了评价流量控制的两个目标,并分析了现有的流量控制机制,最后对基于NAK的流量控制机制和剪枝算法进行了结合,并提出了一种基于时间间隔差值的剪枝算法。
