Motivation
• ScenarioaftermigrationtoSDN/OpenFlow– OpenFlow1.0upandrunning– VirtualizationLayerdeployedwithFlowSpaceFirewall– ProductionL2VPNapplication:Internet2OESS
• Bothintraandinterdomain(OSCARSandNSI)provisioningsupported
• Butwhatnext?– HowdoweprovidemoreadvancedfeaturessuchasIPtrafficrouting

Motivation[2]
• Inresponsetothesechallenges,AmLight joinedInternet2andGEÁNTin2015,withthegoalofcreatingaglobalLayer3infrastructureconnectingRENs,usingOpenSourcesoftwareandSDN/OpenFlow devices.
• Maingoals:– End-to-endprovisioningofLayer3connectivitywithoutusinglegacyrouters
– TransformAutonomousSystems(AS)runningOpenFlow intoIP/BGPtransitnetworks
– ProvideafeasiblemigrationstrategyfromlegacyIP/BGPnetworkstowardsanSDN/OpenFlow approach

ONOSandtheSDN-IPapplication
• WhyONOS?– Free,OpenSource,carrier-gradeSDNOSdesignedforServiceProviders
– Well-definedNorthboundandSouthboundabstractionsandsoftwaremodularity
– KeyPrinciples:• Scalability• HighAvailability• Performance

ONOSandtheSDN-IPapplication[2]
• ONOSSDN-IP– ItisabletoconnectanSoftware-DefinednetworktoexternalnetworksbyusingBGP
– ItprovidesamigrationpathtoSDN
– Itdecreasescosts(L3communicationwithnocorerouters)
