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
