DIMES: A Distributed Internet Measurement and Experimentation System

December 2, 2008
Time: 11:30am-12:30pm
EE Conference Room (MUDD 1306)
Speaker: Prof. Yuval Shavitt, Department of Electrical Engineering, Tel Aviv University

Abstract

Due to the Internet structure and routing the only way to map its topology is by having measurement presence in almost every corner of the Internet. Managing thousands of measurement boxes is impractical, thus, we suggest instead a light-weight software measurement agent to be downloaded by volunteers around the world. The DIMES agent can be executed on every PC and enables us to map the Internet and track its evolution in time in several levels of granularity from the fine router level to the coarse Autonomous System (AS) level. Currently, DIMES has over 17600 installations in over 100 nations around the world, which produce about 4.6 billion measurements.The talk will describe the rationale behind DIMES, and explore some of our recent results on the Internet topology, PoP level map creation, and on measurement optimizations.
