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.
This paper gives the differential equations of the TCP buffer occupancy without congestion in high-bandwidth delay product networks. Then, in view of the fact that the window size in the wide area network is smaller than the delay product of the network bandwidth and the wireless network, Window size can not reach the product of link bandwidth delay (such as satellite network), a Token-based Fast-TCP mechanism is analyzed, and a token-based ACK delay mechanism is derived, not only can greatly reduce the buffer occupancy Amount of conclusions, but also obtain the same throughput as that of TCP in an infinite buffer.The generalization of this conclusion to multiple connections is not covered in previous papers.
