1. Introduction
WebRTC is a protocol suite aimed at real time multimedia exchange
between browsers, and between browsers and other entities.
WebRTC is described in the WebRTC overview document,
[I-D.ietf-rtcweb-overview], which also defines terminology used in
this document.
This document focuses on the data transport protocols that are used
by conforming implementations, including the protocols used for
interaction with intermediate boxes such as firewalls, relays and NAT
boxes.
This protocol suite intends to satisfy the security considerations
described in the WebRTC security documents,
[I-D.ietf-rtcweb-security] and [I-D.ietf-rtcweb-security-arch].
