IP Network Traffic Matrix Inference and Anomaly Detection

I will describe progress in IP network traffic matrix inference, arguably one of the most important technical problems in the engineering and management of large-scale IP networks. In particular, I will discuss tomo-gravity (how to compute accurate traffic matrices for large ISPs in seconds), and anomography (how to accurately detect anomalies, at network-level, for large ISPs in seconds). The methods rely only on ubiquitously available link load and configuration data.

Albert Greenberg is an AT&T Fellow (awarded in 2002 for ground breaking research in IP traffic measurement and network management tools) and the Director of Network Measurement and Engineering Research at AT&T Labs-Research. His current research interests focus on IP networks, as well as IP/Optical network integration. Albert’s recent research includes: novel methods for packet and flow measurement and analysis, traffic matrix inference, anomaly detection, configuration management, IP/MPLS control plane monitoring, MPLS/GMPLS control and management, IP traffic and network engineering, IP fault management and troubleshooting, new route control architectures, database and systems applications, and network security. The research and underlying methodology spans: measurement and engineering of large complex, operational networks and computer systems, modeling, performance analysis, simulation, and statistical inference. Earlier in his career Albert worked in the areas of multiple access channels, Computer Science theory, applied probability, computer engineering and scheduling, wireless and satellite networks, massively parallel computation, and parallel simulation.Albert’s education includes a BA from Dartmouth College in Mathematics (1978, with Honors, Magna Cum Laude), and MS and a PhD in Computer Science from the University of Washington (1981, 1983). In 2005, Albert became Chair of ACM Sigmetrics. In 2004, Albert was awarded AT&T’s Science and Technology Medal for technical innovation in IP network monitoring and management.
