Abstract
Intent was defined as an abstract high-level policy (or instruction)

but also continuous tuning to adjust the measured/actual network

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) ,
