Crack Depth Measurement - Modern Measuring Technique for a Well-known Method
White Paper The new instrument with its probes and measuring technique is introduced. This article described the principle of crack depth measurement by the potential probe method. The dependence of the result on the crack depth for different materials is... [03 Jul 2008]
Inferring Link Loss Using Striped Unicast Probes
White Paper In this paper we explore the use of end-to-end unicast traffic as measurement probes to infer link-level loss rates. We leverage off of earlier work that produced efficient estimates for link-level loss rates based on end-to- end multicast traffic... [03 Jul 2008]
On the Development of IETF-Based Network Monitoring Probes for High Speed Networks
White Paper However, the development of IETF compliant probes so that they sustain the traffic generated in high speed networks is a current challenge, since communication links operating at 100 Mbps or higher rates require efficient packet filtering and... [05 Mar 2008]
On Optimal Probing for Delay and Loss Measurement
White Paper Using active probing to measure delay and loss typically involves sending Poisson probes, on the basis of the PASTA property (Poisson Arrivals See Time Averages), which ensures that Poisson probing yields unbiased estimates. [29 Feb 2008]
Touring the Internet in a TCP Sidecar
White Paper Sidecar transparently injects measurement probes into non-measurement TCP streams, while Passenger combines TTL-limited probes with the often-ignored IP record route option. An accurate router-level topology of the Internet would benefit many... [27 Dec 2007]
Practical Delay Monitoring for ISPs
White Paper The paper shows that only a small number of probes are sufficient to provide an accurate estimate. The paper analyzes various measurement intervals and potential metric definitions. Point-to-point delay is an important network performance measure... [19 Oct 2007]
Using Packet Probes for Available Bandwidth Estimation: A Wireless Testbed Experience
White Paper In addition to presenting performance of the available bandwidth estimation method using packet probes, it also discusses solutions and open issues to provide useful information for other testbed cross-layer protocol evaluations, which are likely... [23 Aug 2007]
Estimating Router ICMP Generation Delays
White Paper By spoofing the source address of the probes to match the destination, these TEs are routed identically to how the direct probes are routed. A number of Internet measurement techniques rely on eliciting ICMP replies from routers in-side the network. [29 Apr 2004]
Creating a Scalable Architecture for Internet Measurement
White Paper We describe an architecture for facilitating a `measurement infrastructure' for the Internet, in which a collection of measurement `probes' cooperatively measure the properties of Internet paths and clouds by exchanging test traffic among themselves. [25 Feb 2004]
Measuring Application Transaction Response Time
White Paper Point-to-point packet inspection -- packets are monitored by probes as they travel between network points. Application response time measurement (ARM) -- ARM is a set of application program interfaces that report performance data back to a... [25 Feb 2004]
