Application Assurance Module (AAM)
The Application Assurance Module (AAM) is designed to manage paths based on the application, verify the application paths periodically against any path change, and monitor the operational statistics and abnormality along the path with Path NI and Runbook.
It is essential to understand what a healthy network looks like, what key applications and services are critical to business operations and their critical path dependencies to minimize costly and unplanned downtime. 
AAM allows users to document the application paths while the network is healthy, including the expected (Golden) paths, the reference map, path nodes and path NIs.
Path NI is used to diagnosis the path related issues, for example,
- L3 failover (the next hop changes)
- Monitoring utilization (QoS drop, CPU/memory high, link error, etc.)
- Configuration consistency (QoS, MTU, etc.)
- Monitor and Verify Application Path
AAM can periodically monitor or verify the application paths and send alerts and emails when paths change. Application paths can be added to a benchmark task so it will be verified when the task is executed. Verification results can be viewed in Application Manager, exported to a CSV file or on a map depicting the differences between the current path and Golden Path.
During troubleshooting, users can verify application paths via the appropriate node, and the system can automatically filter and and find the application paths related to devices on a map.
