Ok, so here is my proposal on how to solve the issue.


  1.  No changes to of draft-ietf-bfcpbis-rfc4583bis. The MUX category of all attributes are set to “TBD”.
  2.  In draft-ietf-mmusic-sdp-mux-attributes, we remove Section 5.27, and the definition of the BFCP MUX categories.
  3.  Based on the change above, the IANA registry will be updated accordingly.

Does anyone object to this?

Suhas, it would be really nice to get your opinion on this.

In general, when it comes to cluster 238, we really need to be careful that similar conflicts don’t occur elsewhere.

Regards,

Christer

Hi,

During the AUTH48 review of draft-ietf-mmusic-sdp-mux-attributes -27 is was realized that draft-ietf-bfcpbis-rfc4583bis-27 defines the mux category “TBD” to all BFCP SDP attributes.

However, with the exception of the ‘floorctrl’ attribute, draft-ietf-mmusic-sdp-mux-attributes defines the mux category “NORMAL” to the BFCP SDP attributes.

Now, both documents explicitly point out that multiplexing of BFCP streams haven’t been defined, which to me sounds like “TBD” would be more appropriate.

But, we need to pick one.

Comments?

Suhas?

Regards,

Christer
