The RTCWEB working group was originally chartered to standardize mechanisms that provide direct interactive rich communication using audio, video, collaboration, games, etc. between two peers' web-browsers, without requiring non-standard extensions or proprietary plug-ins. The result was a set of RFCs from RTCWEB, in addition to many other RFCs from other working groups, all of which are interrelated and had to be published together in what the RFC Editor refers to as a “cluster”. In the end, that cluster comprised more than 40 RFCs and was finally published in January 2021. During the run-up to publication of the cluster, a contradiction was identified between what became RFCs 8829 and 8843. A description of this contradiction was added to both documents to highlight the problem, and state our intention to proceed with publication but quickly initiate an effort to publish updates to the affected documents. The key part of the added text was as follows: “The specific issue involves the handling of "m=" sections that are designated as bundle-only, as discussed in Section 4.1.1 of [RFC 8829]. Currently, there is divergence between JSEP and BUNDLE, as well as between these specifications and existing browser implementations …” The working group is being reconstituted to take up this contradiction, come to consensus on a resolution, and issue Standards Track updates for those two documents. Specifically, the goal of this work is to address only the contradictions regarding "bundle-only" between BUNDLE and JSEP. The resulting aligned solution should avoid impacting the interoperability with SDP Offer/Answer. Finally, the impact on existing implementations that are affected by any change is to be considered. The working group will produce updates to those two documents, and update draft-ietf-rtcweb-sdp accordingly. Updating any other document, or taking up any other issue, is out of scope and will require IESG approval via rechartering. Coordination with the MMUSIC working group to develop this solution will be required.
