OpenTok Architecture

OpenTok architecture is consists of client-side libraries (for JavaScript, Android and iOS) and the OpenTok server SDKs. The OpenTok API platform is based on three important concepts: streams, Connections and Sessions.

  • A stream is a single audio-video signal, which includes a User’s published webcam and microphone feed.
  • A connection is a logical abstraction of a single browser tab’s interaction with a session.The connection is a mechanism through which a browser publishes and subscribes to streams within a session.
  • A session represents an entire video chat environment. It is a collection of connections publishing and subscribing to streams. At a higher level, one can think of a session as a virtual video chat room.
