Ericsson said its Service Provider SDN vision expands the industry definition in three important ways to open new revenue opportunities and costs saving for network operators:
Integrated network control, extending SDN control from the data center into the wide area network, all the way to the radio access network
Service exposure opening network interfaces to applications developers
At Mobile World Congress, Ericsson also announced its commitment to deliver the first commercial Service Provider SDN application in the fourth quarter of 2013. That initial application will be Service Chaining running in the SSR 8000 family of Smart Service Routers.
