Lightweight fairness solutions for XCP and TCP cohabitation

Abstract

XCP is a promising router-assisted protocol due to its high performance and intra-protocol fairness in fully XCP networks. However, XCP is not inter-operable with current E2E protocols resulting in a poor performance of XCP flows when the resources are shared with TCP-like flows. In this paper, we propose a lightweight fairness solution, that can benefit the cohabitation between XCP and TCP in large bandwidth x delay product networks and long-life flows scenarios, as it is shown in our simulation results. © 2008 Springer-Verlag Berlin Heidelberg.
