NANOG Meeting Presentation Abstract

Best Practices for Determining the Traffic Matrix in IP Networks<BR>Level: Intermediate

Thomas Telkamp, Cariden

Thomas Telkamp is responsible for deploying Cariden products, and guides product development. Previously, he worked for Global Crossing as Director of Network Engineering, Director of IP Global Architecture, and Director of Networking Research. Before joining Global Crossing, Thomas worked as a consultant at AT&T-Unisource Communications Services, SURFnet Expertise Centrum, SURFnet, DANTE, and Wunderman Cato Johnson. Thomas\' professional interests include network modeling and analysis, traffic characterization, and traffic engineering.
Abstract: Knowledge of the amount of traffic between source and destination pairs of a network is crucial to fundamental operational tasks such as capacity planning, traffic engineering, and peering management. Router vendors, third parties, academic researchers, and ingenious network engineers have devised multiple ways of collecting and estimating traffic matrices.

This session presents an overview of applications of traffic matrices and operational experiences with the various approaches, including NetFlow-based methods, mathematical estimation models, and MPLS (both RSVP and LDP) methods. Emphasis will be on practical experiences with each method.

The tutorial has been slightly revised since its presentation at the Seattle meeting. In LA, there will be less focus on NetFlow (only new advances will be covered), a more detailed description of how to build a traffic matrix from MPLS LDP counters, more coverage of measuring/estimating peering traffic (external in addition to internal traffic matrix), and another \'real-life\' example.
