 ------------------------------------
 
 Attending:
 
 Dan Schmiedt - willys@clemson.edu
 Chris Small - chsmall@indiana.edu
 Glenn Ricart - Glenn.Ricart@us-ignite.org
 Michael Van Norman -- mvn@ucla.edu
 Deniz Gurkan - dgurkan@uh.edu
 Dale W. Carder - dwcarder@wisc.edu
 Scott Brim
 Charles Chambers - chambers@uh.edu
 John Moore - jhm@mcnc.org
 
 Agenda:
 
1) Agenda Bash
2) OpenDaylight update and discussion 
2.5) OpenDaylight REST API (Dale Carder)
3) I2 AL2S: How to integrate with campus and RON SDN implementations?
4) GEC17 meeting: Agenda? Speakers? etc.

4) GEC17: some network engineers, some academics, list will be available from Heidi once the list is somewhat final.
Campus session (not many domain scientists show up at GENI meetings):
1 - panel on success/horror stories on SDN
2 - pre-cursor to FTW - discuss and coordinate future meetings
3 - operations supporting researchers: applications/experiments that improve operations interfaces (e.g., Clemson GENI ideas applied to operations for production networking benefit; e.g., GeorgiaTech another example with industry partnerships; e.g., multipath, multidomain SDN, very applicable/interesting for this community).  Multilayer SDN e.g. integration of the photonic control plane.
4 - interdomain stuff for SDN in campus/I2/RON: OESS, OSCARS, SDN exchange point, etc.
5 - Brent's spanning tree - OF

Come up with an agenda, share with Heidi, and then bring it to GENI architects attention to add to/revise.

Brent: spanning tree - turn off spanning tree and enable OF?
OF VLAN, hurts multipathing - add to GEC17 agenda

2) OpenDaylight: 
e.g.: XMPP in southbound for Juniper
Southbound interface: may be OpenFlow or otherwise
Different versions of OF can be southbound as well
Java interfaces on SAL so any protocol can be hooked into
Open source
OpenStack uses OVSDB to provision/configure
Project submission: have a working code and then submit

Dale: Cisco controller and OpenDaylight (possibly Floodlight later), API using python, anybody with any such API already available? Use case is on firewall + OpenFlow switch to shunt traffic around the firewall.  Think ScienceDMZ sort of environment.
Chris: OESS can handle multiple controllers, abstraction between controllers
Application development process: pick a controller, the controller location, and then develop according to the API provided by the controller, mostly static flow push may handle most situations
DBUS(?) interface on OESS
 

Internet2 AL2S: useful link for 3) http://www.nitrd.gov/nitrdgroups/images/6/61/1,15,13Internet2-GENI.pdf Slide number 17 has the software architecture.
OESS - OSCARS: OSCARS protocol, build circuits by OESS by OF OR through OSCARS
OSCARS - MPLS
OESS - VLANs 
end point selection done through OSCARS
federated system - coordination between OSCARS & OESS
OESS - OSCARS: independent systems but coordinate

OESS can signal IDC - Clemson 100G network, some OESS UI input from Dan
Clemson campus controller? Couple instances of FloodLight, beta test with commercial controller, campus Science DMZ (CC-NIE)
regional controller instances, campus controller instances - how do they coordinate?

SDN Exchange Point: one step at a time, first build and figure out as we go, particularly the interdomain issues, couple some security functions at the exchange point to strengthen such a inter-domain exchange point.
See https://www.nanog.org/meetings/nanog57/presentations/Wednesday/wed.lightning3.whyte.sdn.controlled.exchange.fabric.pdf  (Google Project Cardigan)

OS3E Demo - http://www.internet2.edu/network/ose/ linked off the ose page but now uses Shib so I don'tknow if you can actually do a demo anymore.

Dan & Brent: Cisco Nexus: cannot turn off spanning tree (HP - cannot turn off anything!)

Cumulus (James Hamilton blog) announcement: linux dist network operating system (http://cumulusnetworks.com/) ODM hardwarehttp://perspectives.mvdirona.com/2013/06/18/CumulusNetworksASneakPreviewOfOneOfMyFavoriteStartups.aspx
Dale:  Not clear how this is different than Pica8 or even Arista.  Brent claims it may be just the linux-ness of it (such as apt-get / yum).

GEC17: send your travel grant application!
