Real-time communications for the web

This article provides an overview of the work that W3C and IETF are doing toward defining a framework, protocols, and application programming interfaces that will provide real-time interactive voice, video, and data in web browsers and other applications. The article explains how media and data will flow in a peer-to-peer style directly between two web browsers. This explains the protocols used to transport and secure the encrypted media, traverse NATs and firewalls, negotiate media capabilities, and provide identity for the media.
