Traffic Engineering in the IETF

Traffic Engineering is now so important as a glue for the Internet that it's worth stepping back to consider what it is, how it works, and what work the IETF is currently engaged in.

This tutorial introduces the concept of Traffic Engineering (TE), describes the basic techniques, runs through the key TE technologies that have been developed in the IETF, and provides pointers to current IETF efforts to enhance Traffic Engineering. Presented at IETF 103, the talk describes recent architectural models such as the Architecture for Application Based Network Operation (ABNO), PCE as a Central Controller (PCE-CC), and a Framework for Abstraction and Control of TE Networks (ACTN), and it mentions new approaches to Traffic Engineering delivered by Segment Routing (SR) and Deterministic Networking (DetNet). It also preview the work on YANG models for the control of TE resources and virtual networks.
