      Overview: Real Time Protocols for Brower-based Applications
                     draft-ietf-rtcweb-overview-05

Abstract

   This document gives an overview and context of a protocol suite
   intended for use with real-time applications that can be deployed in
   browsers - "real time communication on the Web".

   It intends to serve as a starting and coordination point to make sure
   all the parts that are needed to achieve this goal are findable, and
   that the parts that belong in the Internet protocol suite are fully
   specified and on the right publication track.

   This document is a work item of the RTCWEB working group.
