Toronto Networking Seminar

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 23000 installations in over 100 nations around the world, which produce about 6 billion measurements. The talk will describe the rationale behind DIMES, and explore some of our recent results on the Internet topology at the PoP level, and on monitoring the Internet.

Yuval Shavitt received the B.Sc. (Cum Laude), M.Sc., and D.Sc. degree from the Technion, Israel Institute of Technology, Haifa, in 1986, 1992, and 1996, respectively. After graduation, he spent a year as a Postdoctoral Fellow at the Department of Computer Science at Johns Hopkins University, Baltimore, MD. Between 1997 and 2001, he was a Member of Technical Staff at the Networking Research Laboratory at Bell Labs, Lucent Technologies, Holmdel, NJ. Since October 2000, he has been a Faculty Member in the School of Electrical Engineering at Tel-Aviv University, Tel-Aviv, Israel. His recent research focuses on Internet measurement, mapping, and characterization and on datamining peer-to-peer networks. He leads DIMES, a community based Internet measurement and mapping project.
