RSS probeSpam Spikes: A Real Risk to Your Business
White Paper See how changes in spam duration, frequency and intensity among others reveal the spammers' attempts to probe for weaknesses. A close look at MessageLabs own data - derived from processing 1.5 billion emails a week - provides a clear picture of how... [23 Jul 2008]
QoS Monitoring System
White Paper In order to evaluate the networks, a QoS Monitoring System with a QoS Probe and QoS Manager Software is developed. The IQ1000 QoS Probe captures and measures the users' actual packets with passive measurements, and then transmits the measured data... [18 Jul 2008]
GRE Encapsulated Multicast Probing: A Scalable Technique for Measuring One-Way Loss
White Paper Thirdly, it exploits and extends tomographic inference methods in order to extract the performance of probe traffic on customer paths within the network. Internet service providers increasingly wish to monitor the performance of customer traffic... [18 Jul 2008]
A Routing Underlay for Overlay Networks
White Paper This paper argues that designing overlay services to independently probe the Internet - with the goal of making informed application-specific routing decisions - is an untenable strategy. Instead, it proposes a shared routing underlay that overlay... [11 Jul 2008]
Measuring Bandwidth Signatures of Network Paths
White Paper It merely relies on a simple binary test to estimate whether each probe packet has queued in the network or not. This paper proposes a practical and efficient technique, Forecaster, to estimate the end-to-end available bandwidth, and the speed of... [11 Jul 2008]
Continuous Monitoring of Available Bandwidth Over a Network Path
White Paper The method uses active probing with trains of probe packets, and produces estimates in real-time using Kalman filtering. It improves the estimate for each new measurement of the strain of the inter-packet time intervals in a probe packet train. [10 Jul 2008]
A Measurement Study of Available Bandwidth Estimation Tools
White Paper The comparison focuses on accuracy, failure patterns, probe overhead, and implementation issues. Available bandwidth estimation is useful for route selection in overlay networks, QoS verification, and traffic engineering. [10 Jul 2008]
An Analysis of Active End-to-End Bandwidth Measurements in Wireless Networks
White Paper The results from the experiments presented in this paper show that the measured available bandwidth is dependent on the probe packet size (contrary to what is observed in wired networks). Another equally important finding is that the measured link... [08 Jul 2008]
Happy 10th birthday, silicon.com
News The top film was Six Days and Seven Nights, and the day before silicon.com launched into the unknown, Japan launched a probe to Mars. Happy birthday, silicon.com - your favourite business and technology publication is 10 years old. [07 Jul 2008]
Business Intelligence Accelerator: Enabling Organizations to Be More Responsive
White Paper Boundaries are established to rein in runaway queries by end users, limiting the ability to probe answers for unforeseen issues. There is an imperative for businesses to be able to monitor trends and respond more quickly to changing business... [02 Jul 2008]
Probe into loss of 21,000 hospital patient details
News A hospital trust faces possible enforcement action by the UK information watchdog for failing to encrypt a stolen laptop. The Information Commissioner's Office (ICO) will investigate whether Colchester University Hospital NHS Foundation Trust... [30 Jun 2008]
Nasa Mars probe safely touches down
News The first images from the Phoenix Mars Lander have confirmed that the solar panels needed for its energy supply unfolded as planned and that masts for its camera and weather station are in position. A successful touchdown late Sunday was followed... [27 May 2008]
Microsoft: Why we chose ODF support over OOXML
News Following controversy over Microsoft's conduct in pushing through OOXML as an ISO document standard, the Commission announced it would probe OOXML as part of its ongoing antitrust investigation. Microsoft announced on Wednesday it will support ODF... [23 May 2008]
ATM Over ADSL Probe in Telecom Italia Environment
White Paper This paper covers access network performance analysis by deploying ATM over ADSL within Telecom Italia experimental department "EXANET" (Experimental ATM Network). In the scenario presented in this paper, data traffic leaves customer site as ATM... [10 Apr 2008]
Peter Cochrane's Blog: Searching for the truth
Comment And while the baby boomers tend to question the validity of things, probe and research, generations X and Y see no such requirement. Over the past few years I must have seen a dozen new search engines claiming to be the answer to a maiden's prayer. [31 Mar 2008]
