Summary

Abstract

The split of a multihop, point-to-point TCP connection consists in replacing a plain, end-to-end TCP connection by a cascade of TCP connections. In such a cascade, connection n feeds connection n + 1 through some proxy node n. This technique is used in a variety of contexts. In overlay networks, proxies are often peers of the underlying peer-to-peer network. split TCP is also already proposed and largely adopted in wireless networks at the wired/wireless interface to separate links with vastly different characteristics. In order to avoid losses in the proxies, a backpressure mechanism is often used in this context.

In this paper we develop a model for such a split TCP connection aimed at the analysis of throughput dynamics on both links as well as of buffer occupancy in the proxy. The two main variants of split TCP are considered: that with backpressure and that without. The study consists of two parts: the first part is purely experimental and is based on ns2 simulations. It allows us to identify complex interaction phenomena between TCP flow rates and proxy buffer occupancy, which seem to have been ignored by previous work on split TCP. The second part of the paper is of a mathematical nature. We establish the basic equations that govern the evolution of such a cascade and prove some of the experimental observations made in the first part.
