Agora Platform Overview


SD-RTN (Software Defined Real-time Network) is a “smart” network that relies on cloud computing technology and is dedicated to the transmission of real-time audio and video services worldwide, covering 200+ countries worldwide. As a layer of PaaS (Platform as a Service) that provides real-time audio and video services, SD-RTN focuses on the network infrastructure capabilities of audio and video services for upper-layer (SaaS) services, solving common problems for developers, creating a friendly development environment and enabling agile development.

Agora SDK

The Agora SDK is designed to be flexible in incorperating the SDK to real-time applications such as IoT, education, social, financial, and network acceleration.

  • API Usage Guide and Use Cases
  • Productized core module: more customized, split the original SDK on demand
  • Modular audio and video processing interface: easier to integrate third-party SDK

The Agora Native SDK

The Agora Native SDK is available to developers on iOS, Android, Windows, and Mac platforms. It has all the necessary voice and video codecs built-in, along with the logic to access the Agora Global Network and automatically respond to disconnections and varying network conditions. Developers simply need the provided high-level APIs. Everything else is built in.

The Agora Web SDK

The Agora Web SDK enables the development of web apps that have virtually the same functionalities as native apps developed with the Native SDK.
