NFV Plus SDN Equals Dynamism

Nov 11, 2014 by Prayson Pate

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

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?

NFV Performance and Security

Sep 3, 2014 by Prayson Pate

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?

Bridging the Fiber Gap

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?

Cost Cutting is Not Enough

One of the big drivers for Software Defined Networking (SDN) and Network Functions Virtualization (NFV) is reducing CapEx and OpEx.  While attractive and perhaps necessary, cost cutting is not enough to take Communications Service Providers (CSPs) forward.  They need the ability to rapidly develop new wireline services that will drive revenue growth.

 

Follow the Money – How Use Cases Drive Innovation

Apr 7, 2014 by Prayson Pate

I have previously written about how successful innovation is driven by three factors:

  • A customer problem or opportunity
  • Domain knowledge
  • Advances in technology

This blog will dig deeper into the first item: a customer problem or opportunity.  Why is that critical to innovation?  Because that’s what people will pay for.  Here we explore the two categories of real world use cases that represent important elements on any company’s balance sheet: saving money and making money.

A recent court ruling has generally been seen as a blow to the FCC’s Pet Neutrality rules.  What are the details behind the headlines?  This blog sheds some light (if not hair) on these issues.

 

 

 

Delivering the Transition to the Cloud – Lessons for CSPs

Mar 31, 2014 by Prayson Pate

Overture CTO, Prayson Pate

I recently had a chat with Russell Fleischer, CEO of HighJump Software, which is a provider of supply chain management software.  HighJump started with traditional onsite approach to software solutions, but has since moved to the cloud.  HighJump’s Chuck Fuerst describes some of the “Benefits Of Cloud In Logistics” in the December 2013 issues of CIO Review, including flexibility, pay-as-you-go, TCO, incremental features and security.  I asked Russell Fleischer about how HighJump uses the cloud to deliver these benefits.  This blog will describe his thoughts, and will also suggest that the lessons learned by HighJump also apply to Communications Service Providers (CSPs).

 

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.
