Oct 22, 2014 by Prayson Pate

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?

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.

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?

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.

Bridging the Fiber Gap

Overture CTO, Prayson Pate

Fiber is the clear choice for delivering innovative high-speed services at the edge of the network, and the amount of deployed fiber continues to grow.  However, the availability of business access to fiber remains relatively low and even lower for residential areas.  In both cases, the cost of new fiber construction is high.  How do we close the gap between the need for high speed access and the limitations of deploying fiber?

65vSE: Successful Unveiling at BTE

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.
