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. 

5 Predictions for 2014

Sometimes wrong but never in doubt, here are my predictions for networking in 2014.

 

 

 

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.

Overture and CloudNFV joined by Telefonica and Sprint in first ETSI NFV Proof of Concept

Dec 16, 2013 by Mark Durrett

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.

 

 

 

5 Reasons why the Central Office will House the New Telco Cloud

Nov 6, 2013 by Mark Durrett

Overture's D. Mark DurrettI've looked at clouds from both sides now. From up and down, and still somehow it's cloud illusions I recall. I really don't know clouds at all. – Joni Mitchell

That classic 1960s Joni Mitchell song – “Both Sides Now” – often played in my home when I was growing up.  And it frequently pops in my head when I reflect on the complex relationship that telecom operators (a.k.a. Communications Service Providers, or CSPs) have with “the cloud.”  Truth be told, there are many more than two sides to this cloud relationship, but the two I’d like you to consider are the following: a) the cloud as a threat to the traditional telco business model and b) cloud technology as an opportunity. 

NFV Needs SDN

Oct 28, 2013 by Prayson Pate

The idea of Network Function Virtualization (NFV) is separate from that of Software Defined Networking (SDN).  However, for NFV to achieve its full potential, it can’t be limited to converting appliances to software.  NFV needs the principles of SDN to succeed.

 

Update from TIA 2013 - The Future of the Network

Oct 14, 2013 by Prayson Pate

The Federal government may be in a partial shutdown but TIA 2013 "The Future of the Network" was up and running last week in Washington DC.  Here are some observations from the show.

 

 

 

What Does Orchestration Mean for NFV?

Oct 7, 2013 by Prayson Pate

The term “orchestration” is used frequently in discussions about Network Functions Virtualization (NFV).  What does orchestration mean for the cloud data center?  What additional requirements are imposed by NFV?

 

 

 

SDN, NFV and Future Innovation

Sep 25, 2013 by Prayson Pate

There have been many benefits proposed for using Software Defined Networking (SDN) and Network Functions Virtualization (NFV) to modernize the datacenter and network.  Many of these benefits are fairly near term and quantifiable.  However, the biggest value for SDN and NFV is in the enablement of future innovation and services.
