Design, Implementation and Evaluation of a QoS-Aware Transport Protocol
White Paper The paper has developed a prototype of this protocol in the user-space and conducted a large range of measurements to evaluate this proposal under various network conditions. In the context of a reconfigurable transport protocol framework, the... [04 Aug 2008]
Network Services Deployment for QoS Provisioning in a Multi-Layer DiffServ Architecture
White Paper This paper describes in brief the specification and implementation of a layered architecture, which achieves the aforementioned requirements through the definition of specific modules that cater for all the aspects of quality: user-oriented... [04 Aug 2008]
Overview of IEPM-BW Bandwidth Testing of Bulk Data Transfer
White Paper The purpose of these active and passive measurements is to understand what throughputs are achievable, the constraints, and how to optimize, and to make the data and predictions available for net-workers and application tuning. [04 Aug 2008]
Gain Uniformity Optimization of SOA-Based Optical Packet Switching Nodes for Performance and Scalability Improvements
White Paper The methodology is tested and verified using a commercial device with measurements performed on the gain, noise figure, optical signal-to-noise ratio, and power penalty. A design methodology is proposed in this paper that can potentially provide... [18 Jul 2008]
QoS Monitoring System
White Paper The IQ1000 QoS Probe captures and measures the users' actual packets with passive measurements, and then transmits the measured data to the QoS Manager Software. The QoS Manager Software collects the measured data and calculates packet delay... [18 Jul 2008]
A Min-Plus System Interpretation of Bandwidth Estimation
White Paper Significant research has been dedicated to methods that estimate the available bandwidth in a network from traffic measurements. While estimation methods abound, less progress has been made on achieving a foundational understanding of the bandwidth... [11 Jul 2008]
On Cascades of Resonators for High-Bandwidth Integrated Optical Interconnection Networks
White Paper The technique used here has been verified with single-ring experimental measurements. Although the power penalty is generally not prohibitive, it is a parameter which cannot be ignored for the design of complex high-bandwidth photonic interconnect... [11 Jul 2008]
ARCH-Based Traffic Forecasting and Dynamic Bandwidth Provisioning for Periodically Measured Nonstationary Traffic
White Paper In order to have a good sense of nonstationary periodically measured traffic data, measurements were first collected over a period of three weeks excluding the weekends in three different months from an Internet access link. [11 Jul 2008]
The Failure of "The Failure of Poisson Modeling" for Internet Bandwidth Measurements
White Paper As an example, the paper shows that the end-to-end available bandwidth must have finite variance, outline a method for measuring it, and present some experimental data. There is a classic paper, which claims that many parameters of network traffic... [11 Jul 2008]
Bandwidth Measurement in xDSL Networks
White Paper A stepwise algorithm is designed to minimize the effect of ATM traffic shaping for ABR and UBR service classes in xDSL deployments on the bandwidth measurements. This paper presents a design and implementation of a scheme for accurate measurement... [11 Jul 2008]
ATM Dynamic Bandwidth Allocation Using F-ARIMA Prediction Model
White Paper Measurements of high-speed network traffic have shown that traffic data exhibits a high degree of self-similarity. Traditional traffic models such as AR and ARMA are not able to capture this long-range-dependence making them ineffective for the... [11 Jul 2008]
On the Relation Between Bandwidth and Robustness of Indoor UWB Communication
White Paper From these measurements, a single intuitive scalar is derived, which characterizes the small-scale fading encountered by a certain signal. The paper focuses on the effect of small-scale fading on the throughput of communication systems that operate... [10 Jul 2008]
An Analysis of Active End-to-End Bandwidth Measurements in Wireless Networks
White Paper For active, probing-based bandwidth measurements performed on top of the unifying IP layer, it may seem reasonable to expect the measurement problem in wireless networks to be no different than the one in wired networks. [08 Jul 2008]
Audio and Gesture Latency Measurements on Linux and OSX
White Paper With analog I/O there was also a consistent additional bandwidth-dependent latency seemingly caused by hardware. This paper has measure the total system latencies of MacOS 10.2.8, Red Hat Linux (2.4.25 kernel with low-latency patches), and Windows... [03 Jul 2008]
Bandwidth and the Influence of Digital Signal Processing
White Paper This paper looks at DSO bandwidth claims based on the use of DSP to reveal the actual frequency response that may be much lower than the true analog bandwidth required to support reliable, accurate measurements. [03 Jul 2008]
