draft-ietf-mmusic-data-channel-sdpneg.

Wait for WGLC.

CLUE Signaling

draft-ietf-clue-signaling-04

Presenter: Roni Even for Rob Hansen

Slides: http://www.ietf.org/proceedings/92/slides/slides-92-clue-5.pdf

Slide 2

Christer: What was the reason for mandating the DTLS. Is it mandatory to
support, mandatory to use?

Rob Hansen: DTLS was made mandatory to use to avoid video hammer attack and as
general increased security - we had a hum in IETF91. we had explanations in -04
and when we discussed this in -05 room wanted it to be mandatory to use

Christer: Proposing that there is no specific reason to make this mandatory.

Stefan Wenger: That is only one interpretation.

Richard Barnes: Default for new stuff needs to be security. Obviously "must
support" as that is the secure mode. Need discussion of what else might be used.

Mark Duckworth: Also had same discussion regarding security in the framework
document. There says "must support" rather than "must use".

Chairs: Seem to be heading towards "must support" only.

Steven Botzko: Proposed only recommended to support.

Discussion will continue on the list. Chairs take action to start this
discussion.

Rob Hansen (via Jabber) - Have this document reference just reference clue

Miscellaneous remarks
----------------------

Georg Mayer: made proposal to have another look at the LS.

Chairs: Will do this on the mailing list.

Richard Barnes: Could we spend some time hammering out the DTLS discussion.

Chairs:  Not all the relevant people are in the room, so not the best venue. 
The list is better.
