1. Introduction

This section is non-normative.

There are a number of facets to peer-to-peer communications and video-conferencing in HTML covered by this specification:

• Connecting to remote peers using NAT-traversal technologies such as ICE, STUN, and TURN.
• Sending the locally-produced tracks to remote peers and receiving tracks from remote peers.
• Sending arbitrary data directly to remote peers.

This document defines the APIs used for these features. This specification is being developed in conjunction with a protocol specification developed by the IETF RTCWEB group and an API specification to get access to local media devices [GETUSERMEDIA] developed by the WebRTC Working Group. An overview of the system can be found in [RFC8825] and [RFC8826].
