—Most of router mechanisms proposed for fair band-width sharing lack either (1) simplicity due to complexity of intricate per flow management of all connections (e.g., WFQ, SFQ), (2) heterogeneity due to a design targeting a specific traffic type, e.g., RED-PD and Fair RED (FRED) or (3) robustness due to requirement for proper router configurations (e.g.,(More)
The Internet is no longer controlled by a single TCP algorithm. Due to the scalability limitations of traditional TCP algorithms, a plethora of new high-speed TCP congestion control algorithms have been proposed and deployed. Having no standards to follow, these algorithms are ad hoc fixes and some of them have been adopted by various operating system(More)
—The IEEE 802.16 is the standard for broadband wireless access. One promise of this technology (also called WiMAX) is to provide high-speed access to the Internet where the transmission control protocol (TCP) is the core transport protocol. In this paper, we study the impact of network asymmetry in WiMAX on TCP performance. In particular, we investigate the(More)
