Abstract

   Intent was defined as an abstract high-level policy (or instruction)
   used to trigger network operations (not only configuration aspects,
   but also continuous tuning to adjust the measured/actual network
   state to an expected state). This document describes the intent-
   driven management architecture, its key elements, and interfaces.

1. Introduction

   The digital transformation and booming applications and new services
   (e.g., AR/VR) lead to a rapid growth in the variety and volume of
   traffic forwarded by underlying networks (including data centers).
   Existing network technologies and the limited operation and
   management manpower,  make it more challenging. To support efficient
   and faster service delivery (by means of high level of automation) ,
