| 19 | * An interface signifying a class that implements network configuration |

| 21 | * precedence of information, depending on its source: |
| 22 | * <ol> |
| 23 | * <li>Intents (from applications), which override</li> |
| 24 | * <li>Configs (from the network configuration subsystem), which override</li> |
| 25 | * <li>Descriptions (from southbound)</li> |
| 26 | * </ol> |
| 27 | * i.e., for a field representing the same attribute, the value from a Config |
| 28 | * entity will be used over that from the Description. |
