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.
