DNSSD WG Meeting Summary IETF-96

Discussion: Updates to DNS-SD hybrid proxy
Waiting on Stuart Cheshire to edit "Hybrid Unicast/Multicast DNS-Based Service Discovery" draft-ietf-dnssd-hybrid-03<http://tools.ietf.org/html/draft-ietf-dnssd-hybrid-03>, based on input received during WG last call (which completed before IETF-95). Stuart promised revision will be published in August. Once revision is published, WG will confirm that the edits satisfy WG last call input and then the document will be sent to the IESG.

Discussion: DNS Push Notifications
WG agreed at IETF-95 to split out the signalling part from the connection management part. This details of this split has been agreed. The dnsop WG has the responsibility for "DNS Session Signaling", draft-bellis-dnsop-session-signal-00<http://tools.ietf.org/html/draft-bellis-dnsop-session-signal-00> and the dnssd WG has the responsibility for "DNS Push Notifications" draft-ietf-dnssd-push-08<http://tools.ietf.org/html/draft-ietf-dnssd-push-08>. The initial focus will be getting the signalling draft complete, which should happen quickly, and then the DNS Push draft will be revised based on the signaling draft update. The signalling draft authors promised a -01 update by the end of the IETF week, and the dnsop chairs will then ask for dnsop WG adoption.

Discussion: DNS Update and mDNS/hybrid proxy coexistence
Ted Lemon has written "Homenet Naming and Service Discovery Architecture" draft-lemon-homenet-naming-architecture-01<http://tools.ietf.org/html/draft-lemon-homenet-naming-architecture-01> which discusses dynamic DNS update and DNS hybrid proxy services and naming requirements in the context of the homenet WG. In the dnssd meeting, it was agreed that Ted would progress a new "flat homenet" draft which would describe how DNS-SD could work in a homenet with a flat name space. The use of DNS Update alongside a configured hybrid proxy also needs to be discussed for the managed enterprise/campus case.

Discussion: Recommendations for using the hybrid proxy
Ralph Droms gave a short presentation outlining the components of unicast DNS-SD that can be combined in different ways to meet different deployment requirements. The content in the presentation will be incorporated into a new draft describing BCP for unicast DNS-SD deployment. Other aspects may be covered, such as user interface considerations, though UI design is outside the scope of the WG. Tom Pusateri has a candidate draft describing examples of DNS-SD configurations, which will also feed into this process.

Draft review: Privacy Extensions for DNS-SD
Daniel Kaiser discussed updates to "Privacy Extensions for DNS-SD" draft-huitema-dnssd-privacy-01<http://tools.ietf.org/html/draft-huitema-dnssd-privacy-01>. The new revision describes a potential solution based on same-owner and different-owner pairing. The WG expressed interest in the room in adopting the document as a WG work item. The chairs will confirm this consensus on the mailing list. The ADs will discuss where the described pairing protocol should be progressed.
