RSS samplingSampling and Stability in TCP/IP Workloads
White Paper To overcome the performance cost of simulating detailed timing models, computer architects often augment these models with fast functional simulation for fast-forwarding, checkpointing, warm-up, or sampling. [05 Dec 2007]
Sampling in Open Source Software Development: The Case for Using the Debian GNU/Linux Distribution
White Paper The authors argue that a GNU/Linux distribution, such as Debian, is better suited for the sampling of projects because it avoids biases and contains unique information only available in an integrated environment. [03 Apr 2007]
Sampling and Stability in TCP/IP Workloads
To overcome the performance cost of simulating detailed timing models, computer architects often augment these models with fast functional simulation for fast-forwarding, checkpointing, warm-up, or sampling. [06 Dec 2007]
MAINVIEW for IP - Understanding Packet Sampling
White Paper Packet Sampling (or SAMP) is a powerful collection engine that is built into MAINVIEW for IP. It allows MAINVIEW for IP to see all the IP traffic on a TCP/IP stack. It also allows MAINVIEW for IP to collect a number of statistics. [14 Jan 2005]
Exact Sampling of TCP Window States
White Paper This paper demonstrates how to apply Coupling from the Past, a simulation technique for exact sampling, to Markov chains based on TCP variants. This approach provides a new, statistically sound paradigm for network simulations: instead of... [29 Oct 2007]
Traffic Estimation for the Largest Sources on a Network, Using Packet Sampling with Limited Storage
White Paper By sampling packets it is possible instead to estimate the actual packet counts statistically for each source. In the management of networks it is often important to know the largest traffic sources and corresponding packet counts, but impractical... [24 Feb 2004]
Deployment of Sampling Methods for SLA Validation With Non-Intrusive Measurements
White Paper This paper describes the deployment of sampling techniques for SLA validation. It focuses especially on the application of sampling to non-intrusive two-point measurements. First experiments are performed with systematic, random and stratified... [25 Aug 2004]
Comparison of Two Sampling-Based Data Collection Mechanisms for Intrusion Detection System
White Paper Simple random sampling and Stratified random sampling techniques of statistics are introduced to the procedure of data collection for IDS, and formulas used to calculate the sample size of packets based on these sampling techniques are presented. [19 Jun 2008]
Dirig Data Sampling
White Paper Dirig's Data Sampling technology provides unlimited extensibility with an ability to not only monitor and manage any application, but to easily build customized management into the product without the need for any proprietary scripting, coding of... [24 Feb 2004]
Interleaved Sampling
White Paper The known sampling methods can roughly be grouped into regular and irregular sampling. While regular sampling can be realized efficiently in graphics hardware, it is prone to inter-pixel aliasing. On the other hand these artifacts can easily be... [24 Feb 2004]
Valid RF Field Measurements Using Lee Sampling Criteria
White Paper William Lee published his pioneering paper on RF signal level sampling in February 1985. This article explains the background and thinking of his analysis without the fundamental mathematics and also references this with more recent work by David... [03 Jul 2008]
Channel Sampling Strategies for Monitoring Wireless Networks
White Paper This paper explores sampling strategies for monitoring multiple channels in 802.11b/g networks. The paper describes a simple sampling strategy, where each channel is observed for an equal, predetermined length of time, and considers applications... [14 Jun 2006]
An Iterative Approach to Optimal Non-Uniform Sampling and Instantaneous Bandwidth Estimation
White Paper A new approach to the representation and reconstruction of non-bandlimited signals using non-uniform sampling schemes is introduced. This method is optimal in the sense that it requires the minimal sampling rate for exact reconstruction of the signal. [11 Jul 2008]
Active Sampling Approaches in Systems Management Applications
White Paper This paper provides a summary of the approaches on active sampling in distributed computer systems that include the "Active probing" approach for problem diagnosis and active learning for end-to-end performance prediction and resource allocation... [24 May 2007]
New Sampling Expansions for Bandlimited Signals Based on Chromatic Derivatives
White Paper The uniform sampling theorem for bandlimited signals due to Shannon and Nyquist has been generalized in many directions in the last six decades. This extension brings out the derivative sampling theorem as a special case. [03 Jul 2008]
