Towards a user-oriented benchmark for transport protocols comparison in very high speed networks

Abstract : Standard TCP faces some performance limitations in very high speed widearea networks, mainly due to a long end-to-end feedback loop and a conservativebehaviour with respect to congestion. Many TCP variants have beenproposed to overcome these limitations. However, TCP is a complex protocolwith many user-configurable parameters and a range of different implementations.It is then important to define measurement methods so that the transportservices and protocols can evolve guided by scientific principles and comparedquantitatively. The goal of this report is to present some steps towards a userorientedbenchmark, called ITB, for high speed transport protocols comparison.We first present and analyse some results reported in the literature. Fromthis study we identify classes of representative applications and useful metrics.We then isolate infrastructure parameters and traffic factors which influence theprotocol behaviour. This enable us to define scenario capturing and synthesisingcomprehensive and useful properties. We finally illustrate this proposal bypreliminary results obtained on our experimental environment, Grid’5000, wehave built and are using for contributing in this benchmark design.
