Implementation and Performance Analysis of Explicit Loss Notification
Xiaodan Jiang · Jisuanji gongcheng · 2003
In wired network, transmission errors are relatively rare, TCP assumes that segment losses are due to network congestion, and triggers congestion avoidance mechanisms, which essentially make the senders window much smaller. Unfortunately, this is not true for wireless network where, due to handoff and fading channels, transmission losses are more frequent. Explicit loss notification(ELN) claims that if it were possible to explicitly indicate when a particular loss is due to errors induced by the wireless link, then TCP could be modified so as to refrain from going into congestion avoidance. This paper will implements this algorithm, and evaluates it according to the simulation results.
