2. Routing

- draft-ietf-homenet-babel-profile-02 (Juliusz Chroboczek, 10m)

-02 requires a nw sub-protocol for HNCP, and moved to new document.

Committee created, and did not do any protocol work.

Added security section to NOT recommend untrusted links.

update with new reference to source-specific routing; review considerations
Ready for Last Call

- draft-boutier-babel-source-specific (Matthieu Boutier, 10m)

Source Specific extension is required. 

Source Specific will require a New format.
Simpler, but incompatible. 

3. Naming Architecture and Service Discovery

- Distributed Keys for HNCP, Lemon

HNCP offers key sharing but isn't secure. (DTLS but unclear)
protocol picks a 'shared secret'

* node generate public/private key pair
* node shares public key
* now you can do DTLS

Ted willing to write the spec

Barbara Stark(BS): exactly the right approach, willing to help

Juliusz Chroboczek(JC): Really strong direction

BS: Using X509 self-signed could achieve same goal as DTLS.

TL:  Have to elect a signer.  
Should have the conversation of certs or keys are the right choice
    
David Schinazi(DS): this is cool, but one of the sharp edges. 
Should be integral part of design

TL: Think I agree with your motivation, but not with putting in this draft. 
This draft will go faster. 

- Experiences deploying DNCP in home network, Lemon

three HNCP implementations
hnetd
pysyma
shncpd  - used for readability. 

Then things went boom. Stopped working.  SAD!

not ready for prime time.  we are not done yet.

specifiction has some IPv4 addressing
no naming architecture
integrations that just work.

DM(?)  use case different; a bit too much
edge router not running hnetd could not build on Ubuntu

(?): Being forced something to work. some IPv6Ping

Mark Townsley(MT): target market in mind, should be vendors. 

George Michaelson (GM): Should not be disregarded. Real Experience.

Lee Howard (LH): Thank you. Homenet hackathon project? no. Interopt Testing
MT: Many OpenWRT options

JC: 

UI gets graph of top
wiki help

- draft-tldm-simple-homenet-naming-00  (Ted Lemon, 30m)

Name Resolution
Provide Resolution
Multihoming

Andrew Sullivan (AS): Why host has a theory? 
TL: It has to. 
AS: Changing the scope to be simpler, which may be the right thing
TL: What would we have done instead?
AS: Always the worry

BS: happy eyeballs to find which connection works better.  should be what is best connection
DNS Query different responses based on locations. 
happy eyeballs solves DNS

DS: Happy eyeballs solves this 
GM: Solved for one dimension....
TL: Looks bad but solves really simple

DM: multi provisioning domain? 
BS: No DNS Proxy

Eric Vyncke (EV): 
DS: Draft 
Discovering Provisioning Domain Names and Data
draft-bruneau-intarea-provisioning-domains
    
Service Discovery: Discovery Proxy/Advertising Proxy
SC:  Talked out.

Every homenet router
Discover Broker/Proxy
Advertising Proxy
Discover Relay

using DNSSD to browse zones

JC: Enjoying the discussions very much. Many moving pieces
Sit and think on the list of requirements.
list of scenarios. solve those scenarios. 

GM: Right to say close to done. Any confusion at the microphone may be looking 
for a much higher abstraction.  That is multi-dimensional problems. 
Introduce a broker idea. 

SC: Thanks Ted for taking initiative and doing this work. 
Did not have time to sync up on this. Need Diagrams. 
roadmap draft explains how moving parts fit together

AS: Problem getting this published....

TL: Often miss details when not writing code. 

Chairs: go to list for CFA

Ray Bellis(RB):  Thanked Mark Townsley for his service as co-chair
