There are a number of obvious cost and efficiency benefits of Network Functions Virtualization (NFV), but there are also open questions on potential pitfalls.  Can an NFV system meet Communication Service Provider (CSP) requirements for performance and security?  As it turns out, the answer can be yes.  Furthermore, the design requirements for assuring performance and security are closely related.  What are those design requirements?

Service Management in the Brave, New, and Virtualized World

Aug 15, 2014 by Ramesh Nagarajan

Ramesh NagarajanThese are exciting times in the world of Network Functions Virtualization (NFV). NFV fever has truly gripped the market and NFV-washing is fully underway. However, there is real progress underneath and beyond the hype.  Operators are beginning to seriously contemplate commercial deployments of NFV, and are devoting considerable effort to the important topic of NFV service management. Network operations teams at the service providers have been asking the difficult questions of how to manage all of the virtual stuff compared to the physical, custom built appliances they have operated in the past.

“SDN” and “NFV” are on the tips of everyone’s tongues these days. With so much buzz  and confusion, we wanted to get the straight scoop from those who are closest to the action – our team of in-house experts who help Overture’s customers to successfully navigate these evolving technology developments on a daily basis.

So I spoke with Danny Fuston, Vice President of Sales, US East; Erik Kempen, director of sales engineering; Fernando Nunez Orantes, sales director; and Marc Suarez, senior sales engineer to get a sense of what’s happening in the field.

65vSE: Successful Unveiling at BTE

Jun 25, 2014 by Mark Durrett

Overture Mark DurrettLast week Overture participated in Light Reading’s Big Telecom Event, or “BTE,” in Chicago, IL. The event drew 1500 people for its inaugural edition, billed as North America’s premier telecom event. Any first time effort will have its challenges but overall, this was a great event for Overture and, I believe, for the industry.

Network Functions Virtualization is Poised to Drive Innovation and Change in the Metro Service Edge

Apr 21, 2014 by Mark Durrett

Overture Mark DurrettCommunications service providers (CSPs) have begun actively evaluating network functions virtualization, or NFV, as a way to reduce costs and accelerate service innovation.  NFV represents a bold step towards software-defined services and programmable networks, and one that will impact all aspects of the communications industry for years to come.

Behind the Scenes at NFV#5 in Malaga

Feb 25, 2014 by Prayson Pate

Overture CTO, Prayson PateThe European industry body ETSI Industry Study Group (ISG) has been working on Network Functions Virtualisation (NFV) for a year now.  That anniversary was marked by the recent NFV#5 meeting in Malaga, Spain.  Here are a few notes from that meeting.

Meeting Locale

Malaga is in the southwest part of Spain and is not far from Gibraltar.  Several of the attendees took advantage of this fact to participate in pre-meeting day trips down to Gibraltar.  The town of Malaga itself is very pleasant and has a large section of shops and restaurants that make for a pleasant evening stroll and eating adventure.

NFV Evolution Versus Revolution

Dec 23, 2013 by Prayson Pate

Today's Virtualized Network Functions (VNFs) are somewhat limited in number and variety.  Furthermore, many of these VNFs are fairly simple and evolutionary adaptations of todays’ dedicated network appliances.  This is a good start on the road to Network Functions Virtualization (NFV), but it is not enough.  True progress will require a revolutionary approach.

Overture’s Ramesh Nagarajan has recently written in this space about some of the changes that will be required in VNFs, including elasticity, reliability and management. He also touched on how VNFs can be combined to create new services.  This blog will expand on those topics.

Great news on the Network Functions Virtualization front.

You may have read this morning that CloudNFV – the group of vendors Overture joined forces with on NFV – received notification that our proof of concept submission to ETSI was accepted.  There are a couple of public articles that have been published today. We expect to see more later today.

4 Attributes of Openness in Modern Communications

Nov 25, 2013 by Prayson Pate

Openness is one of the most-cited advantages of cloud-based applications, Software-Defined Networking (SDN) and Network Functions Virtualization (NFV).  In this context, what does open really mean?  I posit that there are four key attributes that define openness in this context: documented, standardized, open sourced and inclusive. Any claims of openness by suppliers should be evaluated against these criteria if for no other reason than to clarify their position.
