Whyseparatingthecontrolanddataplanesmatters

1.Transitionsthearchitecturefrombeingdevice-centric tonetwork-centric

1.2.Createstheabilitytoprogram thenetwork

1.3.Enablessignificantimprovementsincontrol andvisibility

1.4.Simplifies thenetwork– evenastrafficflowsbecomemorecomplex

1.5.Facilitatesthecreationofservices withinthenetwork

1.6.Establishesaframeworktovirtualize componentsofthenetwork
