Motivation

• ScenarioaftermigrationtoSDN/OpenFlow– OpenFlow1.0upandrunning– VirtualizationLayerdeployedwithFlowSpaceFirewall– ProductionL2VPNapplication:Internet2OESS

• Bothintraandinterdomain(OSCARSandNSI)provisioningsupported

• Butwhatnext?– HowdoweprovidemoreadvancedfeaturessuchasIPtrafficrouting

usingOpenFlow?– HowdowesupportVPLSandL3VPNsservicesontopofthe

SDN/OpenFlownetwork?

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

– ItprovidesamigrationpathtoSDN

– Itdecreasescosts(L3communicationwithnocorerouters)
