; Morató Osés, Daniel 
(2001)
Contribución a congreso / Biltzarrerako ekarpena 
In this paper we study a-priori bandwidth estimation algorithms for TCP flows. An RTT-based bandwidth allocator is proposed, which outperforms a broad class of peak-rate and static allocation flow switching solutions. Our ... -
