ＡＢＲ业务通过反馈网络状态，动态调整每个连接的信元发送速率，提高网络剩余带宽利用率及消除网络拥塞．节点缓存是ＡＢＲ业务的关键问题．文中提出ＡＢＲ业务缓存处理模型，该模型通过设定持续升速及降速因数和高低缓存门限的方法，合理地利用网络资源，使信息能够公平传输．进一步，根据剩余缓存处理发送，实现完全动态缓存处理．
The ABR service dynamically adjusts the cell sending rate of each connection by feeding back the network status to improve the remaining network bandwidth utilization and eliminate network congestion. Node caching is a key issue for ABR services. In this paper, the ABR service cache processing model is proposed. By setting up the methods of continuous increasing speed, reducing speed factor and high and low cache thresholds, the model makes reasonable use of network resources to make the information fair to transmit. Further, according to the remaining cache processing to send, to achieve full dynamic cache processing.
