The impact of delayed acknowledgments on TCP performance over satellite links
Tanja Lang, Daniel Floreani · 2001
The performance of the Transmission Control Protocol (TCP) over network paths that include a wireless or a satellite link is a very active area of research. A number of papers have been published proposing different ways to improve TCP over these kinds of links, either by new TCP functionality, or by link level enhancements. Very few of these papers consider the delayed acknowledgment strategy that is implemented by many TCP receivers, when presenting their results. In this paper we will show that this acknowledgment strategy can have a significant impact on the performance of TCP and should not be neglected when evaluating new solutions for wireless environments.
