一种新型的ABR流量控制算法

A new ABR flow control algorithm

提出了一种基于随动系统的ABR流量控制算法,该算法应用了跟踪系统的反馈机制,通过检验缓存中的队列长度来控制源端速率。理论证明,这种算法不仅提高了缓存的利用率,同时大大降低了信元丢失率,以及拥塞产生的可能。仿真结果表明,该算法在实际应用中也是可行的。

This paper presents an algorithm of ABR flow control based on follow-up system. According to the feedback mechanism of follow-up system, the algorithm controls the send ratio of the source by checking up the length of the queue in the cache. It is proved in theory that the algorithm not only increases the utilization ratio of cache, but also greatly decreases the drop-out ratio and the possibility of congestion. The simulation result shows that this algorithm is feasible in practical applications.1
