Use Case Overview & Description
...
Intent framework is a system that helps to implement and operate networks that can improve network availability and agility. It takes a high-level business goal (intent) as input, converts it to the necessary network configurations and applies the network changes via network automation and/or network orchestration. Continuously monitoring the status of the network under control, the system validates in real time that the intent is being met, and can take corrective actions when desired intent is not met.
It may contain It contains following functional blocks (to be discussed in Honolulu release):

*Each Requirement should be tracked by its own User Story in JIRA
USE CASE DIAGRAM
Use cases define how different users interact with a system under design. Each use case represents an action that may be performed by a user (defined in UML as an Actor with a user persona).
