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?

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).


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.

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. 

CloudNFV and Overture

Aug 14, 2013 by Prayson Pate

We at Overture are pleased and proud to be participating in the CloudNFV project to support and advance the work of the ETSI NFV ISG.  In this blog I discuss the role that we at Overture are playing in this effort.



Network Function Virtualization (NFV): the Road less Travelled - Part 2

Aug 8, 2013 by Ramesh Nagarajan

Ramesh Nagarajan As I noted in Part 1 of this series, the communications industry is abuzz with vendor and service provider interest in the NFV space. With the potential to completely transform the way communication networks are designed, built and operated, NFV promises a number of benefits such as reduced capital (CAPEX), reduced operational (OPEX) expenditures, reduced time for service turn up and a shift to a “fail fast” model for new services. 

In part 1, we highlighted some of the key industry initiatives, such as the ETSI NFV ISG, that are driving the adoption of NFV, but emphasized that there are two further areas where innovation must take place in order for NFV to be successful.  We noted the areas that have not received as much attention thus far: Firstly, the business models for virtual network functions (VNFs) and secondly, how VNFs are authored for the cloud. Part 1 examined the NFV business models. In this part, we look at VNF authoring for the cloud.

Fail Fast – a new Telco Mindset?

Aug 6, 2013 by Mark Durrett

My first encounter with the term “fail fast” came in 1999 as I was raising venture capital money for the company that would eventually become Hatteras Networks.  Venture capitalists, of course, invest millions of dollars in a number of deals in the hope that one or more will reach an exit (liquidity event) that nets the investors at least a 10x return.  Now, if a company is not going to become wildly successful, the investors want to know very quickly so they don’t continue to invest round after round of cash only to see it all vanish when the company eventually fails.  In this context, the “fail fast” would save the investor lots of money and heartburn.

Notes from Ethernet Europe - Carrier Ethernet 2.0, SDN, NFV, Cloud Convergence

Apr 30, 2013 by Scott Knox

The theme of the recent Ethernet Europe 2013 - held in Frankfurt, Germany - was “SDN, CE2.0 and Cloud Convergence.”  In our busy, multi-tasking world, it seems the trend is to extend that frenzy to industry conferences as well.  This annual Light Reading conference was co-located with the MEF's quarterly face-to-face meeting.  Holding conference sessions on cloud convergence and CE2.0 in one session while right next door, the MEF technologists were hammering out the latest details of the next generation of specifications created an energetic vibe and opportunities to network during the breaks.  Nan Chen from the MEF provided good-natured jabs aimed at the hype surrounding Network Functions Virtualisation (NFV) and Software Defined Networking (SDN) before hinting at a forthcoming announcement from the MEF around cloud services.  In hallway discussions between sessions, the audiences seemed to agree that Chen's foreshadowing was focused on the MEF work on new Carrier Ethernet features designed to make it easier to implement and manage dynamic capacity services. 

The Cloud is a Mindset, Not a Destination

Mar 11, 2013 by Prayson Pate

People talk about the cloud as if it were a specific destination or set of destinations (“My music is in the cloud.”).  In fact, the answer to the question “Where is the cloud?” is “everywhere”.  The cloud is no longer limited to virtualized storage and services in a datacenter.  It is now a metaphor and model for distributed applications built on low cost hardware using Virtual Machines (VMs). 

Reporting in from Ethernet Expo Americas 2012

Nov 13, 2012 by Jeff Reedy

[this article originally appeared in Carrier Ethernet News] 

I always look forward to the Light Reading Ethernet Expo in New York.  The city and the staff of Light Reading deserve a lot of credit for pulling off this event a week after super storm Sandy.  And people were excited to be at the event because there was a lot to discuss and debate.  There has been a lot of change since last November, with the introduction of Carrier Ethernet 2.0 and the rise of Software Defined Networking (SDN), and the most interesting ideas centered on their relevance to the cloud.
