  • Clarifying the role of software-defined networking northbound APIs

    Posted May 6, 2013 - 10:57 am

That much has been established. But what of the oft-mentioned northbound APIs that will let applications tell the controller what they need from the network? What kind of progress is the Open Networking Foundation making on that front?
