"Any fact becomes important when it is connected to another," - Umberto Eco, Foucault's Pendulum.

Virtualized Network Functions (VNFs) are only as valuable as the ability to connect them quickly across the network infrastructure for use in building profitable services.



Service Assurance - What is it? And, how can it keep customers happy?

What's is an SLA?

When a communication service provider (CSP) offers to sell an Ethernet service (e.g. E-Line or E-LAN), they usually include a Service Level Agreement (SLA) for the service. The SLA is a contract spelling out the agreed upon performance metrics used to measure what the end customer's service experience will be. 


Scaling NFV Services - The Role of Federation

Dec 8, 2014 by Ramesh Nagarajan

Ramesh NagarajanOperators around the world have embraced NFV as a transformative initiative and are actively pursuing proofs-of-concept and trials to prove the technology. As we move towards field deployments, it is important to consider the needs for scaling NFV deployments and to bake the requirements into the architecture and technology.

NFV Plus SDN Equals Dynamism

Overture CTO, Prayson Pate

Network Functions Virtualization (NFV) and Software Defined Networking (SDN) combine to create dynamic virtualized services.  There are obvious cost and time benefits, but there are also complexities.  One such complexity is gaining insight into service performance when the service and its supporting network can both change independently.


Network Functions Virtualization: Don’t Fence Me In

Overture CTO, Prayson Pate

Network Functions Virtualization (NFV) offers the promise of reducing cost and increasing innovation by bringing the power of the cloud to the network.  One aspect of NFV is the decoupling and separation of hardware and software, and separation of functions from appliances.  Why discard the power of separation by keeping the virtualized functions fenced inside a data center?

Re-defining OTT: Creating new Revenue Streams from Managed Services run Over the Top

Sep 29, 2014 by Mark Durrett

Overture Mark DurrettToday "over-the-top” or “OTT” strikes fear into wireline Communications Service Providers (CSPs).  What if OTT could inspire thoughts of opportunity rather than eliciting fear of revenue erosion?

The Road Ahead: Reimagining the Third Network

Sep 24, 2014 by Mark Durrett

Mark DurrettThe communications world is undergoing yet another swift, evolutionary shift and it’s bringing a host of new challenges to network operators’ doorsteps. The move to a more fluid, on-demand, and cloud-focused model means being able to react nimbly to changing market and customer needs and expectations, quickly leverage technology innovations, and rapidly capitalize on new service and revenue opportunities. Being able to adapt to this changing environment is key to the continued growth and success of Communications Service Providers (CSP); however, that could be easier said than done.

NFV Performance and Security

Overture CTO, Prayson Pate

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.

Tales from the Field: SDN and NFV

“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.
