 ## Design Goals
 
-*   **Automated Discovery**: Automatically discover network topology information from different data sources (such as UFM, RoCE, etc.).
+*   **Automated Discovery**: Automatically discover network topology information from different data sources (such as UFM, RoCE, label, etc.).
 *   **Scalability**: Support multiple network topology discovery sources and easily extend new discovery methods.
 *   **Real-time**: Be able to reflect changes in network topology in a timely manner.
 *   **Fault Tolerance**: When a discovery source fails, it does not affect the normal operation of the system.
