Cloud proxy

Agora Cloud Proxy is a feature of Agora Voice and Video SDKs. It ensures reliable audio and video connectivity for end users when they connect from restricted network environments.

The following figure illustrates how Agora Cloud Proxy works:

1. The SDK initiates a request to Cloud Proxy.
2. Cloud Proxy returns the corresponding proxy information.
3. Agora SDK sends data to Cloud Proxy. Cloud Proxy receives the data and transmits it to Agora SD-RTN™.
4. Agora SD-RTN™ returns data to Cloud Proxy. Cloud Proxy receives the data and sends it to the SDK.

1. Integrated the SDK and prepared the development environment.
2. Contacted Agora support and provided the following information to request Cloud Proxy:
   • App ID
   • Cloud Proxy service usage area
   • Concurrency scale
   • Network operator and other relevant information
