Presentations

This is the first announcement for the NISS Affiliates Internet Tomography Technology Day, which will be held at NISS headquarters in Research Triangle Park on Friday, March 28, 2003. The program committee consists of James Landwehr (Avaya Labs), J. S. Marron (SAMSI and UNC; Chair), Robert Nowak (Rice) and Walter Willinger (AT&T Labs Research).

We look forward to an exciting day that helps kick off next fall's SAMSI Program on Network Modeling for the Internet (see http://www.samsi.info/200304/int/int-home.html). Click here for the program (PDF file).

Internet Tomography is inference about aspects of large scale networks on the basis of peripheral information. These aspects include network structure and topology, loss rate and delay distribution, and the origin-to-destination traffic matrix. Such knowledge is important dynamic routing, optimized service provision, service level verification, and detection of anomalous or malicious behavior. The inference is challenging because of the heterogeneous and largely unregulated structure of the Internet. Furthermore, one cannot rely on the cooperation of individual servers and routers. The result is a series of "inverse problems," with strong parallels to signal processing problems such as tomographic image reconstruction, system identification and array processing. A good introduction to network tomography can be found at http://www.niss.org/affiliates/internet030328/binyu.pdf
