Abstract
We study the impact of the modifications proposed for
TCP in the context of short file transfers. The two most
important proposals are the increment of the initial win-
dow size (IW) [3] and the Limited Transmit algorithm
(LT) [1]. We analyze analytically and by simulations the
effect of these proposals on the TCP latency. We demon-
strate that the LT proposal reduces the TCP latency sim-
