This tutorial explains how MPLS is being used to engineer traffic flows inside ISP networks. We present the entire set of components that are used in the traffic engineering architecture. We then demonstrate the exact function of each component. A number of examples compare how each component helps improve the current destination-based forwarding network model, i.e., traffic engineering benefits over traditional layer 2 networks.

Finally, new features for traffic engineering are described and practical network deployment scenarios examples are presented.
