Abstract
This memo introduces network measurement intent, namely the process
of realizing user or network operator to allocate network states as
needed. And it can be as a specified user case of intent based
network.

1. Introduction
Since the development and implementation of intent based network
(IBN) cannot be separated from accurate network state perception,
accurate on demand network measurement technology is becoming more
and more important. The combination of network measurement
technology and IBN can achieve network performance acquisition based
on user/network administrator intent-based, verify whether network
measurement results meet the measurement intent, and further improve
the accuracy of the configuration in IBN.
As the rise of IBN, different groups have different definitions of
intent. For example, in [I-D.irtf-nmrg-ibn-concepts-definitions]
defines intent as intent fulfillment and intent assurance. However,
all different definitions of intent have some common characteristics,
and can be classified according to
[I-D.irtf-nmrg-ibn-intent-classification]. And in order to combine
the network measurement intent with the existing drafts of IBN, we
define the components of the network measurement intent processing
process as follows:
o Intent Translation
o Intent Orchestration and pre-Verification
o Data Collection
o Intent Compliance Assessment

At the same time, according to
[I-D.irtf-nmrg-ibn-concepts-definitions], network measurement intent
can be classified as network intent, operational task intent or some
other kinds of intent. And a detailed flow of network measurement
intents will be given
2. Network Measurement Intent
Network measurement intent refers to the on-demand measurement of the
network state based on the user/network operators' perceived intent
