Measuring Probing Response Curves over the RON Testbed
نویسندگان
چکیده
The probing response curves of an Internet path depict the first-order statistics of packet-train output signals (dispersion or rate) as a mathematical function of the input signal. Recent theoretical analysis showed that several useful path characteristics (e.g., raw capacity, crosstraffic rate, and residual bandwidth of the tight link) can be inferred from probing response curves [1]. To gain insight into the response curve properties of real Internet paths, we present a measurement study over the RON testbed covering 272 different paths among 17 RON hosts. We show that manually assisted estimation of the tight link capacity is possible using relatively short packet-trains and that for 98% of the paths measured, the available bandwidth is limited by an edge link with

CO2 Measurement of Synthetic Biogas by Passing It through Dilute NaOH Solution
The feasibility of measuring CO2 content in biogas was evaluated in this research. Firstly, Curtipot pH simulator was used to visualize the titration behaviors of various percentages of dissolved CO2 in a wide range of concentrations of NaOH solution. As a general output of those simulations, it was shown that when the titration curves of different CO2 conte...
متن کاملDynamis: Dynamic Overlay Service Composition for Distributed Stream Processing
This paper addresses the problem of mapping software services onto an overlay network, specifically, the probing to locate suitable nodes on which to instantiate or configure data processing operators. We propose a distributed algorithm, called Dynamis, that can improve existing probing algorithms. Experimental results on the PlanetLab testbed show that Dynamis can dramatically reduce probing o...
متن کاملDesign, Deployment, and Use of the DETER Testbed
The DETER testbed provides infrastructure for conducting medium-scale repeatable experiments in computer security, especially experiments that involve malicious code. Built using Utah’s EMULAB, the DETER testbed has been configured and extended to provide stronger assurances for isolation and containment. This paper provides information on the capabilities of the DETER testbed and discusses the...
متن کاملA Plan for Malware Containment in the DETER Testbed
The DETER testbed provides a shared Internet-accessible environment where security researchers can safely run experiments and companies can test their security products. Experimentation with malware in DETER has so far been limited to simulated worms, which only simulate the spreading action without actually infecting any computer systems. This paper outlines a set of architectural and procedur...
