AT&T, Colt Claim Major SDN Advance

AT&T and Colt are claiming a significant breakthrough in next-generation service development with the news that they have achieved SDN interoperability.

The two operators have tested and trialed what they describe as a "standard application programming interface (API) infrastructure" that enables SDN architectures from different network service providers to interoperate.

The official announcement is confirmation of the Light Reading report from October 12, when Colt Technology Services Group Ltd (London: COLT) discussed the development but did not identify its partner (though SDN community talk suggested it was AT&T). (See Colt Boasts Multi-Operator SDN Service Breakthrough.)

AT&T Inc. (NYSE: T) regards SDN interoperability as critical to its service development plans. Talking today at the MEF16 event in Baltimore, Josh Goodell, vice president of AT&T Network On Demand, said that federating SDN services is critical to the giant operator, as its enterprise customers increasingly expect services to be rolled out globally, not just across the US.

Goodell pointed to SDN federation as "an area we believe there is going to be a lot of opportunity, by taking the value proposition we have within our own footprint and expanding it outward."

The AT&T exec included SDN federation in a trifecta of things the industry needs to tackle in order to fully exploit SDN and NFV capabilities for the development of new services, with the other two being a better VNF-onboarding process, and open universal CPE to support virtualized functions at the edge.

Re: Do we have to go through the whole Ethernet NNI situation all over again?
Ray, curious what, if any, service assurance implications are here for inter-operability? We know AT&T uses vProbes from RADCOM for service assurance -- is there a good chance COLT will do the same if inter-operability here is the ultimate goal?

 

RADCOM is currently trialing with 9 Tier-1 CSPs for its cloud native MaveriQ VNF.

Do we have to go through the whole Ethernet NNI situation all over again?
Will operators need to go through the whole unilateral interop interconnect process with each partner as they largely did with carrier Ethernet, or will there be an easier, quicker and more efficient way to hook up SDN-eneabled networks?

Understanding the full experience of women in technology requires starting at the collegiate level (or sooner) and studying the technologies women are involved with, company cultures they're part of and personal experiences of individuals.

During this WiC radio show, we will talk with Nicole Engelbert, the director of Research & Analysis for Ovum Technology and a 23-year telecom industry veteran, about her experiences and perspectives on women in tech. Engelbert covers infrastructure, applications and industries for Ovum, but she is also involved in the research firm's higher education team and has helped colleges and universities globally leverage technology as a strategy for improving recruitment, retention and graduation performance.

She will share her unique insight into the collegiate level, where women pursuing engineering and STEM-related degrees is dwindling. Engelbert will also reveal new, original Ovum research on the topics of artificial intelligence, the Internet of Things, security and augmented reality, as well as discuss what each of those technologies might mean for women in our field. As always, we'll also leave plenty of time to answer all your questions live on the air and chat board.
