Abstract

   RFC7575 defines Intent as an abstract high-level policy used to
   operate the network. Intent management system includes an interface
   for users to input requests and an engine to translate the intents
   into the network configuration and manage their lifecycle. Up to
   now, there is no commonly agreed definition, interface or model of
   intent.

   This document discusses what intent means to different stakeholders,
   describes different ways to classify intent, and an associated
   taxonomy of this classification. This is a foundation for discussion
   intent related topics.
