CAIDA’s IPv6 measurement and analysis activities

Friday, April 29th, 2011 by kc

In pursuit of more rigorous data on IPv6 deployment, CAIDA has undertaken four IPv6 measurement and analysis exercises: address allocation data; traceroute-based topology; DNS queries from root servers; and a global survey of network operators in 2008.


Unsolicited Internet Traffic from Libya

Wednesday, March 23rd, 2011 by Emile Aben

Amidst the recent political unrest in the Middle East, researchers have observed significant changes in Internet traffic and connectivity. In this article we tap into a previously unused source of data: unsolicited Internet traffic arriving from Libya. The traffic data we captured shows distinct changes in unsolicited traffic patterns since 17 February 2011.

Most of the information already published about Internet connectivity in the Middle East has been based on four types of data:


Caidagram: visualizing geographically annotated Internet measurements

I post this article to describe the results of my five month visit to CAIDA and UC San Diego, and to thank the organizations that collaborated to make this work possible.


proposition: International Bureau of Internet Statistics

Friday, January 9th, 2009 by kc

Last month I submitted two proposals to the National Cyber Leap Year call for input from the U.S. Networking Information Technology Research and Development (NITRD) Program. I submitted two ideas, the International Bureau of Internet Statistics, and Cooperative Measurement and Modeling of Open Networked Systems (COMMONS, a two-year old idea). The Bureau of Internet Statistics still strikes some as batty, but over the holidays I caught up on some panicky OECD state-of-malware-landscape papers on how uninformed we are and how little data we have, while the only concrete recommendation in the “ITU’s study on the financial aspects of network security: malware and spam” report was

Although the financial aspects of malware and spam are increasingly documented, serious gaps and inconsistencies exist in the available information. This sketchy information base also complicates finding meaningful and effective responses. For this reason, more systematic efforts to gather more reliable information would be highly desirable.


internet telemetry, v6

Wednesday, December 10th, 2008 by kc

i gave a (faster, less understandable) version of this talk (pdf or slides+audio quicktime) at the October 2008 ARIN meeting in Los Angeles (original October version) and again to ISOC’s advisory council meeting in November. motivation: the end of the current addressing architecture, with scant understanding of how to retain all its positive features in the face of inevitable change. a topic i worry about more each year.

DITL 2008: phase one complete.

Friday, March 28th, 2008 by kc

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. As with last year’s DITL (DITL2007 announcement, DITL2007 summary), we tried to capture a complete 48-hour interval of traffic to as many DNS root nameservers as could participate, and also invited other data providers to participate on terms compatible with their data sharing policies. if you engage in ongoing measurement of an operational network, and collected data for some or all of 18-19 mar 2008, it’s not too late to contribute data or metadata to DITL2008!
