Use Cloud Proxy
Last updated 2021/03/12 03:41:06

Introduction

To allow users to use the Agora RTC SDK in environments with restricted network access, Agora provides a cloud proxy. Users only need to add specific IP addresses and ports to the firewall whitelist, and call the API to configure the Agora cloud proxy service.

Working principles

  1. The Agora SDK sends a request to the Agora cloud proxy. The Agora cloud proxy returns the proxy information.
  2. The Agora SDK sends data to the Agora cloud proxy. The Agora cloud proxy forwards the data to Agora SD-RTN™ (Software Defined Real-time Network).
  3. Agora SD-RTN™ sends data to the Agora cloud proxy. The Agora cloud proxy forwards the data to the Agora SDK.

Implementation

Preparation

  1. Download the Agora RTC SDK.

  2. Integrate the SDK and prepare the development environment. For details, see QuickStart Guide.

  3. Contact Agora technical support and provide the following information:

    • Your App ID.
    • The regions using the cloud proxy.
    • The concurrent scale.
    • Network operators.

Add whitelist

Refer to the corresponding table according to the SDK version you are using, add all the IP addresses and ports in the table to your firewall whitelist.

Some IP addresses and ports in the following table are for testing purposes only. In a production environment, you must apply to Agora for the official IP addresses and ports that replace them.

v3.2.0 or later

When using the UDP cloud proxy, whitelist the following addresses and ports:

Protocol Destination IP address Port Comment
UDP 140.210.77.68 (Mainland China) 8443 Used to access the signaling service
UDP 125.88.159.163 (Mainland China) 8443 Used to access the signaling service

Call API

v3.3.0 or later

For SDKs v3.3.0 or later, you can call setCloudProxy to enable cloud proxy.

  1. After adding the whitelist, call setCloudProxy, and set proxyType as UDP_PROXY(1).

  2. Test the audio and video call functionality.

To disable the cloud proxy service, call setCloudProxy and set proxyType as NONE_PROXY(0).

v3.2.1 or earlier

For SDKs v3.2.1 or earlier, you can call setParameters to enable cloud proxy.

  1. After adding the whitelist, refer to the following sample code to enable cloud proxy:

     // Enables the cloud proxy server and configures the service by default.
 setParameters("{\"rtc.enable_proxy\":true}");

  2. Test the audio and video call functionality.

To disable the cloud proxy service, call setParameters("{\"rtc.enable_proxy\":false}");.

Considerations

  • You need to call setCloudProxy before using the cloud proxy function. For example, if you need to enable cloud proxy to join a channel, call setCloudProxy before joinChannel. If you need to enable cloud proxy to conduct a lastmile test, call setCloudProxy before startLastmileProbeTest. The settings of setCloudProxy takes effect within the lifecycle of RtcEngine.
  • UDP cloud proxy does not support pushing streams to the CDN or relaying streams across channels.
