D14: Netflow, IPFIX, and Beyond: Integrated Routing, Traffic Analysis, and Modeling for highly Accurate Network Engineering

Topic: Control and Management of High Performance Networks

Duration: 9:45am - 12:15pm
Dr. Cengiz Alaettinoglu, Packet Design Inc.

Network management has traditionally been carried out using SNMP polling, sometimes augmented by codebook-based correlation. More recently, flow-based analysis has provided further insight into the application and traffic dynamics of IP networks. But periodic polling cannot capture the complex and dynamic layer 3 operations of IP networks, and flow-based analysis is typically viewed on a link-by-link basis. These techniques do little to help network engineers explain the often unpredictable and intermittent behaviors caused by the routing dynamics of IP networks. They are forced to make educated guesses about the global state of the network to infer root causes from symptoms and plan changes effectively.

This seminar examines the use and limitations of flow-analysis tools such as Netflow and the upcoming IPFIX standard, and how an emerging technology called route analytics works with traffic-flow analysis to provide network-wide understanding of traffic for better troubleshooting and planning. We will show "route-flow fusion" can be used to increase the reliability and predictability of IP networks for more sensitive and demanding converged applications.

Cengiz Alaettinoglu is a fellow at Packet Design, Inc. Currently he is working on scaling and convergence properties of both inter-domain and intra-domain routing protocols. He was previously at the USC Information Sciences Institute, where he worked on the Routing Arbiter project. He co-chaired the IETF Routing Policy System Working Group to define the Routing Policy Specification Language and the protocols to enable a distributed, secure routing policy system. Alaettinoglu received a B.S. degree in computer engineering in 1988 from the Middle East Technical University, Ankara, Turkey; and M.S. and Ph.D. degrees in computer science in 1991 and 1994 from the University of Maryland at College Park. He was a Research Assistant Professor at the University of Southern California, where he taught graduate and undergraduate classes on operating systems and networking from 1994 to 2000. He has given numerous talks at NANOG, IETF, RIPE and APNIC meetings, as well as at ACM and IEEE conferences and workshops.
