Clarifying the role of software-defined networking northbound APIs

With software-defined networking the control of the network is pried out of the data handling devices and centralized on a controller that uses a common protocol, OpenFlow, to direct the switches on the southbound side. 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? Network World Editor in Chief John Dix put the question to Robert Sherwood, CTO of Big Switch Networks and head of the ONF's Architecture and Framework Working Group, which is responsible for multiple things, including the creation of these northbound APIs.

Efficiency key to Avaya's success, Giancarlo says

Charles Giancarlo spent more than a decade at Cisco Systems and was widely considered a likely heir to Chairman and CEO John Chambers before he left last year for investment company Silver Lake Partners. Then Silver Lake orchestrated a private-equity buyout of Cisco rival Avaya, and Giancarlo stepped in as interim president and CEO. In January, former JDS Uniphase chief Kevin Kennedy will take over day-to-day operations as president and CEO, and Giancarlo will become chairman. Stephen Lawson of the IDG News Service spoke with Giancarlo on Tuesday after he delivered the opening keynote at VoiceCon in San Francisco.
