1. Introduction
This document defines a data model for DS-Lite [RFC6333], using the
YANG data modeling language [RFC7950]. Both the Address Family
Transition Router (AFTR) and Basic Bridging BroadBand (B4) elements
are covered by this specification.
As a reminder, Figure 1 illustrates an overview of the DS-Lite
architecture that involves AFTR and B4 elements.
