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

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”

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).
