Queue Dynamics Analysis of TCP Veno with RED

This paper aims to study the queue dynamics of TCP Veno with RED in the wired-wireless heterogeneous networks. The authors first develop a fluid-flow model of TCP Veno with RED over heterogeneous network, and then use the classical linear feedback control theory to analyze it. Analysis results reveal the relationship between the RED queue oscillation and the network parameters. The authors use simulation tool to validate our analysis, and show how to stabilize the router queue and improve the co-existence of TCP Veno with TFRC.
