== DPRIVE ==

The DPRIVE (DNS Privacy Exchange) WG met on Monday 5 November.  Presentations included dns-over-tls, dns-over-dtls, dprive-privacy-eval. There was a presentation on a new possible encryption mechanism dprive-dnsenc.  We discussed a path forward, and then the chairs did an interpretive dance. 

== DNSSD ==

Chairs opened the meeting with agenda bashing and document status update (documents accepted as WG documents):

__draft-ietf-dnssd-hybrid-01__
* Will consider for WG last call today
* Does this document meet the requirements of RFC 7558?
* Looking for document shepherd

__draft-ietf-dnssd-push-02__
* Needs review against dnssd-hybrid specification
* Will consider for WG last call today
* Looking for document shepherd

__draft-ietf-dnssd-mdns-dns-interop-02__
* WG last call complete 2015/07; comments discussed at IETF-93
* Rev -02 published includes updates from WG last call comments
* Needs final review by WG before forwarding to IESG
* Looking for document shepherd

The chairs asked if there was consensus in the room to do a short WG last call review to confirm that draft-ietf-dnssd-mdns-dns-interop-02 addresses the comments during the previous WG last call.


'''__Summary meeting results:__'''

* draft-ietf-dnssd-push: after 2nd implementation ready for WG last call
* draft-ietf-dnssd-hybrid: ready for WG last call; will send to IESG when draft-ietf-dnssd-push is ready for IESG 
* draft-ietf-dnssd-mdns-dns-interop: ready for WG last call review and then send to IESG

'''__Document discussions:__'''

__Scalable DNS-SD (SSD) Threat, draft-otis-dnssd-scalable-dns-sd-threats-02__

Doug Otis gave a presentation about the -02 revision, which replaces draft-otis-dnssd-mdns-xlink-06 and draft-rafiee-dnssd-mdns-threatmodel-03.  Based on WG comments, draft-otis-dnssd-scalable-dns-sd-threats-02 needs additional editing to use a more accurate model of DNS, mDNS and other name resolution mechanisms as the basis for the threat analysis.

__DNS Push Notifications, draft-ietf-dnssd-push-02__

Stuart Cheshire gave a brief review of updates to the -02 rev.  The WG then discussed whether the document is ready for WG last call. Consensus is that the WG would like to see an interoperable implementation prior to WG last call.


__Hybrid !Unicast/Multicast DNS-Based SD, draft-ietf-dnssd-hybrid-01__

Stuart Cheshire gave a brief review of updates to the -01 rev.  The WG consensus in the room was that the document is ready for WG last call.  However, because this document depends on draft-ietf-dnssd-push-02, this document will be held and then sent to
the IESG when draft-ietf-dnssd-push-02 is ready to go to the IESG.


__Optimizing DNS-SD query using TXT records, draft-aggarwal-dnssd-optimize-query-00__

Dave Thaler reviewed the previous presentation of draft-aggarwal-dnssd-optimize-query-00 and presented additional details of allseenalliance.org/framework/documentation/learn/core/system-description/advertisement-discovery. The AllSeen Alliance document describes extensions to DNS-SD/mDNS defined by AllSeen.  The request from the WG is to write a document accommodating AllSeen requirements while adhering as closely as possible to draft-ietf-dnssd-hybrid-01.
