Network Working Group C. Jennings Internet-Draft Cisco Intended status: Informational November 10, 2014 Expires: May 14, 2015 WebRTC Dependencies draft-jennings-rtcweb-deps-05 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 May 14, 2015.

Jennings Expires May 14, 2015 [Page 1] Internet-Draft WebRTC Dependencies November 2014 1. Dependencies The key IETF specifications that the W3C GetUserMedia specification normatively depends on is: [I-D.ietf-rtcweb-constraints-registry], [RFC2119]. The key IETF specifications that the W3C WebRTC specification normatively depended on are: [I-D.ietf-rtcweb-audio], [I-D.ietf-rtcweb-data-channel], [I-D.ietf-rtcweb-data-protocol], [I-D.ietf-rtcweb-jsep], [I-D.ietf-rtcweb-rtp-usage], [I-D.ietf-rtcweb-security-arch], [I-D.ietf-rtcweb-transports], [I-D.ietf-rtcweb-video], [RFC2119], [RFC3264], [RFC3388], [RFC5245], [RFC7064], [RFC7065] and informatively depends on [I-D.ietf-rtcweb-overview], [I-D.ietf-rtcweb-security]. These IETF drafts in turn normatively depend on the following drafts: [I-D.ietf-avtcore-6222bis] (now [RFC7022]), [I-D.ietf-avtcore-multi-media-rtp-session], [I-D.ietf-avtcore-rtp-circuit-breakers], [I-D.ietf-avtcore-rtp-multi-stream-optimisation], [I-D.ietf-avtcore-rtp-multi-stream], [I-D.ietf-httpbis-header-compression], [I-D.ietf-httpbis-tunnel-protocol], [I-D.ietf-mmusic-msid], [I-D.ietf-mmusic-sctp-sdp], [I-D.ietf-mmusic-sdp-bundle-negotiation], [I-D.ietf-mmusic-sdp-mux-attributes], [I-D.ietf-payload-rtp-opus], [I-D.ietf-payload-vp8], [I-D.ietf-rtcweb-alpn], [I-D.ietf-rtcweb-data-protocol], [I-D.ietf-rtcweb-security], [I-D.ietf-rtcweb-stun-consent-freshness], [I-D.ietf-tls-applayerprotoneg] (now [RFC7301]), [I-D.ietf-tram-alpn], [I-D.ietf-tsvwg-rtcweb-qos], [I-D.ietf-tsvwg-sctp-dtls-encaps], [I-D.ietf-tsvwg-sctp-ndata], [I-D.ietf-tsvwg-sctp-prpolicies], [I-D.reddy-mmusic-ice-happy-eyeballs]. TODO - verify if there is a dependency on [I-D.ietf-httpbis-http2] or not. Right now security normatively depends on [I-D.ietf-rtcweb-overview]. Right now video normatively depends on [I-D.grange-vp9-bitstream], [I-D.ietf-payload-rtp-h265]. The drafts webrtc currently normatively depends on that are not WG drafts are: [I-D.grange-vp9-bitstream], [I-D.reddy-mmusic-ice-happy-eyeballs]. Right now transports normatively depends on [I-D.reddy-mmusic-ice-happy-eyeballs]. Jennings Expires May 14, 2015 [Page 2] Internet-Draft WebRTC Dependencies November 2014 A few key drafts that the work informatively depends on: [I-D.alvestrand-rtcweb-gateways], [I-D.hutton-rtcweb-nat-firewall-considerations], [I-D.ietf-avtcore-multiplex-guidelines], [I-D.ietf-avtcore-rtp-topologies-update], [I-D.ietf-avtcore-srtp-ekt], [I-D.ietf-avtext-rtp-grouping-taxonomy], [I-D.ietf-dart-dscp-rtp], [I-D.ietf-mmusic-trickle-ice], [I-D.ietf-rmcat-cc-requirements], [I-D.ietf-rtcweb-use-cases-and-requirements], [I-D.kaufman-rtcweb-security-ui], [I-D.lennox-payload-ulp-ssrc-mux], [I-D.nandakumar-rtcweb-sdp], [I-D.roach-mmusic-unified-plan], [I-D.westerlund-avtcore-multiplex-architecture].
