Abstract
MultiPath TCP is a recent TCP extension that allows the spreading of data on several paths. While the behavior of TCP mainly depends on its congestion control scheme, MultiPath TCP presents more subtle patterns. In order to better understand its behavior, this work first proposes broad measurements and analyzes of a large number of experiments. We compare the performance of MultiPath TCP with those of TCP with a new metric that we introduce and we observe how these performances evolve with different factors. We consider three kinds of connections : bulk-transfers, small files and lossy transfers. The second part of this work is a mathematical approach where a TCP throughput stochastic model is extended for MultiPath TCP. We propose a simple formula for the throughput and validate it through experiments.
