This page describes CAIDA collaborators and subcontractors in the DNS-ITR project.
Principal Investigator: kc claffy
Funding source: NSF 0427144 Period of performance: September 15, 2004 - August 31, 2009.
Internet Systems Consortium (ISC)
Internet Systems Consortium (ISC) is a not-for-profit corporation internationally known for their long-term operational experience and leadership in DNS activities. ISC operates the F root name server that anycasts to more than 70 locations worldwide. ISC is the founding member of the DNS Operations and Analysis Research Center (OARC) that brings together key operators, implementers, and researchers to search for solutions to DNS problems.
Collaboration with ISC gives CAIDA access to operationally relevant data collected at the very top of the Internet hierarchy. ISC also has a subcontract from CAIDA to build a testbed and to perform experiments characterizing DNSSEC performance.
Georgia Institute of Technology
Georgia Institute of Technology (GA Tech) is one of the oldest and most respected polytechnical universities in the United States. In collaboration with CAIDA, Prof. George Riley (Computer Engineering) and his students conduct laboratory simulations of DNS anycasting methods. The goal of these experiments is to estimate the effectiveness and robustness of using anycast for DNS root servers.
Measurement Factory is a software company offering quality tools for performance testing and protocol compliance. Under a subcontract with CAIDA, Duane Wessels developed a system for collecting and exploring statistics from busy DNS servers - DNS Statistics Collector software. He also conducts surveys, studying properties of DNS resolvers in the real Internet, and laboratory modeling experiments, testing DNS properties in depth.
University of Auckland, New Zealand
University of Auckland is New Zealand's largest university internationally known for its learning and academic excellence and research leadership. We collaborate with Prof. Nevil Brownlee (Department of Computer Science) who developed a Network Traffic Flow Measurement Tool NeTraMet. We use this tool to monitor performance of the root and gTLD servers.
Executive summary: ISC will build a testbed whose magnitude and capacity match a typical collection of TLD servers (not including anycast mirrors). We will replicate the root and .com zones in the testbed, and will present various loads and measure performance under those loads. The loads presented will not just be simple lookups, but will include various mixes of database updates, with and without various DNSSEC extensions.
Georgia Tech provides services to the University of California, San Diego supporting CAIDA in its research effort studying the performance of the Domain Name System and potential enhancements or replacements.
