Network Working Group C. Jennings Internet-Draft Cisco Intended status: Standards Track March 20, 2016 Expires: September 21, 2016 WebRTC Dependencies draft-jennings-rtcweb-deps-10 Abstract This draft will never be published as an RFC and is meant purely to help track the IETF dependencies from the W3C WebRTC documents. Status of This Memo This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF). Note that other groups may also distribute working documents as Internet-Drafts. The list of current Internet- Drafts is at http://datatracker.ietf.org/drafts/current/. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress." This Internet-Draft will expire on September 21, 2016.
