The document outlines the different layers and technologies involved in building real-time communication applications using WebRTC. It discusses client-side and backend architectures for both web and native apps. Key components include client APIs, WebRTC browsers, plugins, signaling servers, ICE servers, and media servers. Example real-time communication solutions like appRTC, PeerJS, and custom DIY options using various open-source WebRTC components are also covered.
