Assurance is a key function of Intent-Based Networking (IBN). It is responsible for validating that the network is actively satisfying the business intent and objectives set forth by the operator. Network Assurance involves three main aspects:
continuous verification of system behavior by examining run time states and events,
providing visibility and insights into the operation of the network for validation, understanding and prediction,
remediation of issues including faults and policy violations, thereby enabling a closed-loop control paradigm.
