What's New http://www.caida.org/data/active/trmethod-200808.xml Wed, 27 Aug 2008 00:00:00 GMT This dataset is useful for studying the effects that the choice of a traceroute probing method has on the inferred IP path. Several traceroute probe methods exist, each designed to perform better in a scenario where another fails. This dataset contains traceroute paths from 8 vantage points on Archipelago to a variety of destinations using up to 6 different probing methods per destination. This is the dataset analyzed in the IMC 2008 paper, Traceroute Probe Method and Forward IP Path Inference.

Jun 4-5 What's New http://www.caida.org/data/monitors/monitor-map-ark.xml Wed, 21 May 2008 00:00:00 GMT As a part of CAIDA's mission to improve the integrity of operational Internet measurement and management, CAIDA collects, curates, and distributes active Internet measurement data to researchers worldwide. In 2007, CAIDA deployed the active measurement platform Archipelago (Ark) and the team-probing methodology for collecting measurements to all of the routed IPv4 prefixes on the Internet. The resulting IPv4 Routed /24 Topology Dataset is available on request to academic and non-profit researchers and CAIDA members. Ark has the potential to support many other Internet measurements as well. This map and table show Ark monitors and their approximate geographical location What's New http://www.caida.org/publications/presentations/2008/arin_survey/ Mon, 7 Apr 2008 00:00:00 GMT This slideset was presented at the ARIN XXI Public Policy Meeting in April 2008 What's New http://blog.caida.org/best_available_data/2008/03/28/ditl-2008-phase-one-complete/ Fri, 28 Mar 2008 00:00:00 GMT (Blog Entry) CAIDA, ISC, OARC, and The Measurement Factory managed to repeat our annual Day in the Life of the Internet data collection experiment this year using a 2-day window of 18-19 March 2008. ... we gathered much more data than last year (2.5x more in bytes) with considerably less pain. So although it reflects only a slice of Internet activity, we believe this is (again) the largest synchronized data set about the Internet ever made available to the research community. What's New http://www.caida.org/research/dns/roottraffic/comparison06_07.xml Fri, 28 Mar 2008 00:00:00 GMT During the last two years, CAIDA and the Operations, Analysis, and Research Center (OARC) have coordinated and conducted annual, large-scale collection events targeting the DNS root nameservers in an attempt to capture A Day In The Life of the Internet (DITL). This page characterizes traffic captured at anycast instances of the C, F, and K DNS root nameservers during these two measurement events held during the first Tuesday and Wednesday of the month in January 2006 and January 2007.

We already perform large-scale topology measurements on Ark, and we recommend researchers use this new dataset, which employs an improved measurement methodology. The new IPv4 Routed /24 Topology Dataset collected on Ark extends back to Sep 13, 2007 and overlaps with the last five months of skitter data.

The monitors probe a random destination in every routed /24 (currently around 7M in the global routing tables) on an ongoing basis. Data collection began in September 2007. With the availability of the new IPv4 Routed /24 Topology Dataset, we are switching over our topology measurements from the old skitter monitor infrastructure to the new Ark infrastructure. skitter data will no longer be collected beginning February 8 2008, though historical skitter data will continue to be made available.
