摘　　要：针对因特网上对收发双方数据信息的高速率、高质量的要求,提出基于权重的反馈优先流量控制算法。此算法将不同类型的报文分组给予不同的权重,在每一个分组中保留一位域以标志拥塞,同一分组的报文队列根据接收方的信用值和等待时间设置优先级,对于高权重高优先级的反馈报文实行优先强占的策略,综合考虑数据信息的传输速率和传输质量,以提高网络的资源利用率。实验证明这种流量控制算法可以有效地防止网络的拥塞崩溃现象,从而达到了高效地利用网络资源的目的。Address on the high- speed and high - quality requirements of sending and receiving data information on Intemet, raises the feedback priority flow control algorithm based on the weight. This algorithm will distribute different weights to different types of messages groups, and in each group keep a domain to mark the congestion, set priorities in the queue of the same group according to credit and waiting time of the receiver, for the high - weight and high - priority feedback packet perform the priority dispossession strategy, enhance utilization of network resources considering the data transfer rate and transmission quality. The experiment proves that it can pievent congestion collapse in network by using the flow control algorithm,realize to use network resource efficiently.
