Abstract
When TCP operates in wireless networks, it suffers severe performance degradation because TCP’s fast retransmit/fast recovery (FR/FR) is often triggered regardless of congestion when a packet is lost due to wireless transmission errors. Although several loss differentiation schemes have been proposed to distinguish the cause of triggered FR/FRs, there has been a little try to find out an appropriate responding method to utilize the detection information of a LDA. In this paper, we observe the relationship between a responding method and TCP’s performance, and investigate the best way to respond to the FR/FRs non-related to congestion in order to improve TCP’s performance to the max. Our experiment results emphasize the importance of the responding method, which is overlooked in previous works, and suggest the best response for the FR/FRs non-related to congestion.
