提出了一种新的主动队列管理方案，用于路由器中，既能处理最优流量，又能处理多媒体流量。大多数可用的主动队列管理方案只考虑TCP流，这导致在处理多媒体流时出现意想不到的拥塞。队列大小和数据包接收率是计算队列中标记概率的常用参数。在标记概率计算过程中使用往返时间（RTT）比其他方法有优势。我们讨论了当我们之前论文中的框架用于多媒体流的速率适应时，我们的方法的适用性。通过在包标记概率计算中使用RTT，我们可以确保在队列耗尽之前在尽力而为和多媒体流中降低速率。所提出的方法最具影响力的特点是它可以与现有系统一起工作。仿真结果证明了该方法的有效性。
A novel active queue management scheme is proposed to employ in the routers that deal with both the best-effort traffic flows and multimedia traffic flows. Most of the available active queue management schemes consider only TCP flows, which results in unexpected congestion when dealing with multimedia flows. The queue size and packet receiving rate are the common parameters to calculate the marking probability in the queue. The use of round trip time (RTT) in the process of marking probability calculation has advantages over other approaches. We discuss the applicability of our approach when the framework in our earlier paper is used for rate adaptation in multimedia flows. With the use of RTT in packet marking probability calculations, we can assure rate reduction in both best-effort and multimedia flows before a queue gets exhausted. The most influential feature of the proposed approach is that it can work with the existing systems. The soundness of the proposed approach is inferred from the simulation results.
