Internet-Draft             WebRTC Dependencies                March 2015


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-alpn],
   [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], and [I-D.ietf-mmusic-trickle-ice].

   These IETF drafts in turn normatively depend on the following drafts:
   [I-D.ietf-rtcweb-fec], [I-D.ietf-payload-flexible-fec-scheme],
   [I-D.ietf-mmusic-trickle-ice],
   [I-D.nandakumar-mmusic-proto-iana-registration],
   [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-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], [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.martinsen-mmusic-ice-dualstack-fairness].

   Right now security normatively depends on [I-D.ietf-rtcweb-overview].

   The drafts webrtc currently normatively depends on that are not WG
   drafts are: [I-D.martinsen-mmusic-ice-dualstack-fairness],
   [I-D.nandakumar-mmusic-proto-iana-registration].

   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],

1.1.  Time Estimates

   The following table has some very rough estimates of when the draft
   will become an RFC.  Historically these dates have often taken much
   longer than the estimates so take this with a large dose of salt.
