[MMUSIC] updating draft-ietf-mmusic-sctp-sdp

[Salvatore Loreto <[e-mail]>]

Hi there,

there has been a quite large discussion within the rtcweb mailing list and
especially the w3c webrtc mailing list.

Some of the points discussed are specific of how to negotiate the 
'datachannel' protocol over SDP,
and I lean on putting those in a separate draft and not in this one.

However there are things that are general enough to is worth to insert 
in this draft
as they can be used in other protocols that eventually will be specified 
in the future
running on top of SCTP, or STCP over DTLS.

  'streams' is some of those attributes,
  so I am proposing to insert in the new version of the draft the 
following text

  xxx.  Streams Attribute

    The 'streams' attribute indicates time the number of streams to be supported by the association.
    If this attribute is not present, the implementation should provide a default, with a suggested value
    of 16.


          streams-attr           =  "a=streams:" streamsnumbers
          streamsnumbers         =1*DIGIT


As I said, all the other attributes that has been discussed are tied to 
the 'datachannel'  protocol identifier ( to be registered?),
which is describing the format of the media... so they should go in a 
different draft.

opinion, thoughts are welcome and required

thanks
Salvatore
