摘    要:给出了在高带宽时延乘积网络中无拥塞丢包的TCP缓冲区的占用量的微分方程,然后针对广域网中窗口大小小于网络带宽时延乘积和无线网络中,由于误码丢包而使窗口尺寸无法达到链路带宽时延乘积(如卫星网)的情况,分析了一种基于令牌的Fast-TCP机制,得出基于令牌的ACK延时机制,不仅能够大大减少缓冲区的占用量结论,而且可获得与TCP在无限缓冲区下的同样的吞吐量.还把这个结论推广到多连接的情况,在以前论文中没有涉及.

关 键 词:TCP  ACK  带宽-时延乘积  微分方程

Abstract:In this paper, the authors first provide a close form differentiate formula to analyze the buffer requirement for zero loss of TCP in networks with high bandwidth delay product. Then, A Token Based Fast-TCP algorithm is analyzed and modeled in WANs when the window size is smaller than Bandwidth-Delay Products (BDP) or in satellite networks where window size is not allowed to be larger than BDP because link errors. It proves that Token Based ACKs delay algorithm not only reduce buffer occupancy largely, but also gain the average same throughput as TCP with infinite buffer size as well. The authors also apply the analysis to multiple connection case that is not included in previous work.
Keywords:TCP  ACK  bandwidth-delay products  differentiate formula
