A-priori flow bandwidth estimates for dynamic bandwidth allocation in ISP access links
Aracil Rico, Javier
; 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 ... -
Analysis and stochastic characterization of TCP flows
Aracil Rico, Javier; Morató Osés, Daniel ; Izal Azcárate, Mikel (Springer, 2000)
Artículo / Artikulua
Since the most Internet services use TCP as a transport protocol there is a growing interest in the characterization of TCP flows. However, the flow characteristics depend on a large number of factors, due to the complexity ... -

Characterizing Internet load as a non-regular multiplex of TCP streams
Aracil Rico, Javier; Morató Osés, Daniel (IEEE, 2000)
Contribución a congreso / Biltzarrerako ekarpena
A commonly accepted traffic model for a large population of Internet users consists of a multiplex of Poisson-arriving heavy-tailed streams with the same constant rate (M/G//spl infin/). We show that even though such a ... -
Delay-throughput curves for timer-based OBS burstifiers with light load
Izal Azcárate, Mikel ; Aracil Rico, Javier ; Morató Osés, Daniel ; Magaña Lizarrondo, Eduardo (IEEE, 2006)
Artículo / Artikulua
The OBS burstifier delay-throughput curves are analyzed in this paper. The burstifier incorporates a timer-based scheme with minimum burst size, i. e., bursts are subject to padding in light-load scenarios. Precisely, due ... -
