1. High Level Concept Wired and Wireless L2 access switches mark DSCP on ingress to Access network. Access traffic passed up to L3 routers. Aggregation routers have L3/DSCP steering configuration? SD-WAN attached to aggregation network and can steer to WAN or internet based on DSCP Ubercontroller program SD- WAN to steer traffic based on DSCP. Uber-controller program SD-LAN controller to set DSCP based on OpenFlow 5- tuple Uber-controller program SD-WLAN controller to set DSCP based on 5-tuple Adding and removing flows from mapping and groups causes switch rules to update

2. Atrium/Boulder/Aspen Enterprise V1 SD-WAN Switch WiF i Internet Pipe WAN Pipe L2 Access Network L3 Branch Network WiF i Eth er

3. Phase I deliverable 2 Pod Testbed Each Pod includes – 2 LAN switches, 2 WLAN Switches – 1 SD-WAN switch – 1 x Internet link – 1 x dedicated (Cat 7 cable) “WAN” link – 4 x SFB clients – ODL instance as pod level controller Directly pushing OpenFlow rules to LAN switches Using WLAN REST APIs to program WLAN switches Using SD-WAN REST APIs to program SD-WAN “system”

4. Phase I Scale and Performance 100 users per branch/pod 3 branches 10Mbs WAN link GBE Internet link Traffic generation to starve Internet based traffic (demonstrate value of policy based steering to non-congested WAN).

6. High-level concepts Northbound interface with Skype-for-business: collect 5-tuple info SD-WAN solution provides intelligent routing internet – corpnet – At L3 building routers / aggregation routers – Controlled by ‘uber-controller’ Mark streams with correct DSCP Value – not based on ACL or L7 deep packet inspection (not scalable) – OpenFlow Need to remove config after flow tears down
