DSP-based bottleneck bandwidth estimation

Simulation Modelling Practice and Theory, 2009
Abstract This paper presents a new passive technique for estimating the bottleneck bandwidth based on transferring the Gaussian kernel density estimation of the packets inter-arrival times to the frequency domain. The resulting spectrum contains information about the transmission time of the bottleneck link and can reveal information about multiple ...

Variable bandwidth kernel hazard estimators [PDF]

Journal of Nonparametric Statistics, 2003
Variable kernel hazard estimators, where the bandwidth is allowed to depend on the exposure, are considered together with the kernel hazard analogue to Abramsons approach to bias reduction, see Abramson (1982). The theoretical analysis of the kernel hazard analogue to Abramsons approach shows that the variable bandwidth should be weighted according to ...

Bandwidth estimation for wireless video transmission

2004 IEEE International Conference on Multimedia and Expo (ICME) (IEEE Cat. No.04TH8763), 2005
This work deals with layered video transmission over wireless networks. We focus on deriving the required bandwidth provisioning for each layered video given their respective QoS target. We model the layered video traffic by a discrete time batch Markovian arrival process (DBMAP) with marked transitions.

Estimation of Bandwidth in Bridged Home Networks

2007 5th International Symposium on Modeling and Optimization in Mobile, Ad Hoc and Wireless Networks and Workshops, 2007
Knowledge of end-to-end available bandwidth can significantly improve the performance of multimedia applications in a home network. A number of heterogeneous link technologies are predicted to coexist in future home networks. In this paper, we compare the performance of a few existing bandwidth estimation tools in a home network testbed constructed ...

Estimating the statistical bandwidth of a time series

Biometrika, 1990
SUMMARY In many time series and signal processing applications such as spectral estimation, signal-to-noise estimation and frequency response estimation it is imperative to have a good estimate of the bandwidth of the time series. In many scientific applications deconvolution is carried out over the signal-dominated part of the spectrum resulting in a ...

Bandwidth estimation schemes for TCP over wireless networks

IEEE Transactions on Mobile Computing, 2004
The use of enhanced bandwidth estimation procedures within the congestion control scheme of TCP was proposed recently as a way of improving TCP performance over links affected by random loss.

The effective bandwidth of a multitaper spectral estimator

Biometrika, 1995
Summary: The bandwidth of a spectral estimator is a measure of the minimum separation in frequency between approximatively uncorrelated spectral estimates. We determine an effective bandwidth measure for multitaper spectral estimators, a relatively new and very powerful class of spectral estimators proving to be very valuable whenever the spectrum of ...

Towards multihop available bandwidth estimation

ACM SIGMETRICS Performance Evaluation Review, 2009
We evaluate the algorithm proposed in [1], which estimates the residual bandwidth on each hop of an Internet path using a para-metric model which consists of a Kelly queueing network. The evaluation is driven by simulation based on real network traces over a two node path. Correction factors are proposed and evaluated to cope with deviations from model

DIChirp: direct injection bandwidth estimation

International Journal of Network Management, 2007
AbstractIdeally, network bandwidth estimation algorithms should be independent of the end system performance. If end system capabilities are involved, then the measurement will be of the system throughput and will not indicate a correct assessment of network bandwidth. Packet dispersion‐based active bandwidth estimation schemes including Pathload, TOPP

On the accuracy of the effective bandwidth regenerative estimation

2014 6th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT), 2014
We consider the effective bandwidth (EB) estimation in the networks with the regenerative input. Based on the Lindley's-type recursion for the workload process in discrete and continuous time, we apply a large deviation approach to construct a regenerative estimate of the required EB in the nodes of tandem queuing networks.
