Software defined networking (SDN) and network functions virtualization (NFV) have been buzzwords for years now, but the promise of these technologies is starting to reach fruition as network providers move from proof of concept to production use on the network.
This is particularly true for NFV, which is being pushed by the carriers themselves who serve as the primary users of the technology. The result is a faster acceptance of the technology compared with SDN.
Many large carriers are aggressively moving to NFV as a way to more flexibly adjust and deploy networking functions as needs change and opportunities emerge, as Sanjay Bhatia told RealTimeCommunications last fall, GENBAND Vice President, Solutions Marketing & Strategy.
“Many of them are even changing their entire organizations for it,” he said, “but it’s a very large undertaking and process, so it is going to take a lot of time and planning.”
NFV is being deployed on a case by case basis by operators as a phased migration. When operators see an opportunity to leverage NFV, they’re making one-off migrations to the technology. This is quietly building NFV use and moving it beyond proof of concept experiments.
It also doesn’t hurt that NFV proof of concepts are being driven by actual customer environments, and this means that successful tests show actual value for NFV users and are then quickly pulled into production use.
“With these point solutions, they take a slice off the network to address a very specific problem, such as the enterprise SBC, for instance,” explained Bhatia. “This is what we are seeing, certainly in the short term, as there are very few true greenfield opportunities for networks.”
Bhatia will be discussing these real-world NFV applications at NFV & SDN Expo in Fort Lauderdale, Florida on Tuesday, January 26.
In a session entitled, “NFV - from PoC to Reality,” Bhatia will examine NFV use cases, drivers and how the network equipment vendors are positioning themselves in this market. Alan Percy, Senior Director of Product Marketing at Dialogic, will co-host the session.
The event is also collocated with the upcoming ITEXPO which is happening Jan 25-28 in Fort Lauderdale, Fla., focused on communications solutions for the enterprise mid-market, resellers and service providers.
