This document proposes several use cases of Intent-Based Networking (IBN) and a methodology to differ each use case by following the lifecycle of a real IBN system. It includes data collection for system awareness in the IBN system and the construction of the IBN system. This construction consists of intent translation, policy translation, policy verification, policy deployment, policy monitoring, policy validation, policy optimization, and intent report. Practice learnings are also summarized to instruct the construction of next generation network management systems with the integration of IBN techniques. Finally, this document discusses three aspects for the deployment of IBN systems on the real world. They are Multi-Domain Dichotomy for IBN, the Integration of IBN and Network Digital Twin, and IBN with Artificial Intelligence (AI). |
