| ### Architecture Description |
| |
|  |
| |
| ### Node Description |
| |
| * `Registry` : The registry center responsible for service registration and discovery in dubbo-go |
| * `Consumer` : The service consumer that calls remote services |
| * `Provider` : The service provider that exposes services |
| |
| ### Process Description |
| * `0. register` : When the service provider starts, it will automatically register its services with the registry center |
| * `1. subscribe` : The service consumer will subscribe to the services it needs from the registry center upon starting |
| * `2. notify` : The registry center returns service registration information to the service consumer. When the subscribed service changes, the change data will be pushed to the consumer |
| * `3. invoke` : The service consumer selects a suitable service address based on the service addresses obtained from the registry center and initiates a request after applying the load balancing algorithm |
