摘要

本文初步研究了突然往返变化对不同版本TCP性能的影响。结果表明，批量TCP传输的端到端good - put可能受到RTT变化的严重限制，这主要是由于TCP的超时估计和快速恢复阈值的非适应性。本文提出了一个在RTT突变和随机丢包环境下评估TCP性能的模型，并概述了TCP未来可能的改进。

TCP in networks with abrupt delay variations and random loss

This paper provides a preliminary investigation of the effect of abrupt round-trip variations on the performance of different versions of TCP. It is shown that end-to-end goodput of a bulk TCP transfer can be severely limited by variations in RTT primarily due to the non-adaptiveness of TCP's timeout estimation and fast recovery thresholds. The paper proposes a model for evaluating the performance of TCP in environments with abrupt RTT changes and random packet loss and outlines possible future TCP improvements.
