摘要: TCPs/AQMs算法在多种环境下的组合研究已十分广泛,但主要采用TCP Reno与各种AQMs算法在低带宽下的组合。利用显示反馈的思想,提出一种以H-TCP/BLUE为基础模型的高带宽拥塞控制算法,称为H-TCP*/BLUE*。仿真结果表明,新的组合算法比基础算法提高了带宽利用率、RTT公平性和友好性。

Abstract: TCPs/AQMs algorithm has been a combination of a wide range of research in a variety of circumstances,but the main use of TCP Reno and a variety of low-bandwidth AQMs algorithm.This paper proposes a new high-bandwidth congestion control algorithm,known as H-TCP*/BLUE*.The simulation results show that a combination of the new algorithm than the algorithm-based enhanced bandwidth utilization,RTT fairness and friendliness.

Key words: H-TCP, BLUE, bandwidth utilization, RTT fairness, friendliness
