摘要 介绍了目前应用最为广泛的拥塞控制机制AIMD和一种通用的公平性评价标准——比例公平性评价标准,以及Floyd在AIMD基础上根据回路延时(RTT)不同的连接的公平性要求提出的恒定速率(CR-constantrate)窗口更新机制;在分析上述机制和评价标准在卫星网络中应用存在的缺陷的基础上,将区分服务的思想引入AIMD拥塞控制机制,提出了基于服务的AIMD算法和基于丢包率的公平性评价方法. This paper introduce the AIMD which is a fashion congestion control mechanism applied in TCP and the method of proportion fairness evaluation at first, then introduce CR（Constant Rate） witch is developed from AIMD by Floyd . After analyze the defect above mentioned,we bring the idea of DiffServ into AIMD and put forward SB-AIMD（Service Based AIMD） and DBF（the probability of packet Dropped Based Fairness evaluation）.
