| QoS Metering |
| ============ |
| |
| Recommendations |
| --------------- |
| |
| Metering is fully supported, though it is recommended that changes to metering |
| be avoided unless necessary to meet a specific need. Metering can sometimes lead |
| to counter-intuitive behavior, such as unexpected limitations in network performance. |
| |
| Description |
| ----------- |
| |
| Aether Supports three levels of QoS metering: |
| |
| * Per-Device-Per-Application. These meters apply to specific flows between devices |
| and applications. As a device may connect to many applications, it may have many |
| flows, and therefore many different meters may be specified. These meters are |
| configured in the Application page of the GUI. |
| |
| * Per-Device. These meters apply to the aggregate of all flows from a device, |
| regardless of the application the device is connecting to. These meters are |
| configured in the Device-Group page of the GUI. |
| |
| * Per-Slice. These meters apply to the aggregate of all flows from all devices to |
| all applications within the slice. These meters are configured in the Slice page of the GUI. |
| |
| These three levels of metering are depicted below: |
