ABwE: A practical approach to available bandwidth estimation
free download

We report on a new tool developed for monitoring available bandwidth in the range from several Mbits/s to 1000 Mbits/s. The tool is based on the packet pair dispersion technique. It has been in experimental use at SLAC for several months and it has been demonstrated at

Available bandwidth estimation in IEEE 802.11-based wireless networks

Available bandwidth estimation is a vital component of admission control for quality-of- service (QoS) in both wireline as well as wireless networks. In wireless networks, the available bandwidth undergoes fast time-scale variations due to channel fading and error

Review of bandwidth estimation techniques

End-to-end available bandwidth estimation is very important for bandwidth dependent applications, quality-of-service verification and traffic engineering. Although several techniques and tools have been developed in the past, producing precise estimations in real

Bandwidth selection for nonparametric distribution estimation
free download

The classic nonparametric estimator of the distribution function is the empirical distribution function (EDF). This estimator is widely used in practice despite the known fact that smoothing can produce ef- ficiency gains in finite samples. Proposals to use kernel smoothing for distribution estimation

Bandwidth selectors for multivariate kernel density estimation
free download

Kernel density estimation is an important data smoothing technique. It has been applied most successfully for univariate data whilst for multivariate data its development and implementation have been relatively limited. The performance of kernel density estimators

Spatio-temporal available bandwidth estimation for high-speed networks
free download

We present a new packet dispersion based active probing scheme for available bandwidth estimation that (1) overcomes system I/O bandwidth limitations on high-speed (> 1Gbps) networks and (2) determines the location of a paths tight link. The scheme is based on the

Currently Open Shortest Path First (OSPF) is the most commonly used and promising intra- domain internet routing protocol where packets are routed along shortest paths to the destination. The shortest path computation is based on some static link costs and the

Bandwidth selection for weighted kernel density estimation
free download

Weighted kernel-density estimates (wKDE) are broadly used in many statistical areas, for instant, density estimation under right-censoring. However, bandwidth selection could be a problem by reweighting the kernels. In this paper, we investigate the methods of bandwidth
