Hello Christer,

the titel of the (future) RFC will not exclude any SCTP transport modes.
And a comprehensive and future safe protocol specification should cover all existing ones, which is "DTLS/SCTP/IP" as well as "SCTP/UDP/IP" (RFC 6951).
These two SCTP transport modes should be indicated as well, independent of potential intentions to be used soon.
Codepoint space could be reserved, placeholder sections tagged as "not yet supported" of "for further studies", etc, but the worst case would be any kind of interaction issues in future.

My view,
Albrecht

Subject: [MMUSIC] DTLS-over-SCTP, anyone?

Hi,

draft-ietf-mmusic-sctp-sdp currently defines the SDP O/A procedures for SCTP, SCTP-over-DTLS, and DTLS-over-SCTP.

As we know, SCTP-over-DTLS is used for the WebRTC data channel.

My question is: does anyone intend to use DTLS-over-SCTP?

Regards,

Christer
