OSS/BSS: The Sticking Point for Success in SDN/NFV

By | Blog | No Comments

In a recent article on SDxCentral.com they talked about OSS/BSS being the main challenge to successfully implementing NFV and SDN solutions in your network. This is so true, and one of the primary drivers of what we at Itential are trying to achieve with our Pronghorn Application Platform. Traditional OSS is built around the idea of a very static network, with very static services, built on top of legacy equipment that happily hums along within that paradigm. SDN and NFV introduce a level of dynamic flexibility that I truly believe it…

OpenStack is MANO? No…No, It Is Not

By | Blog | No Comments
There was an article on Tech Target about a year ago with the question, "Are OpenStack and NFV MANO interchangeable?"  A colleague stumbled on this recently and asked my opinion on the topic, how true it may have been then and how true it may be now. I can see where people that don't get what MANO is could ask this question. The short answer is that OpenStack is a part of MANO, specifically the VIM. Of course, as this is a blog post, I am going to give a little longer answer...

The Current State of NFV: Virtual Network Functions

By | Blog | No Comments

  This may be one of the shorter blogs in this series, as it is very straightforward. In this one I want to focus on Virtual Network Functions, where they are today and where they are headed. In recent years, as cloud environments have become more and more common, vendors have begun creating virtualized versions of their network gear. Whether it is Nokia/ALU, Juniper, Cisco, or whoever, they all have a version of their major products that they have inserted a “v” in front of to enter the virtual arms race….

Are You Abusing The Term “SDN”?

By | Blog | No Comments

I had an interesting conversation today after a client meeting with a vendor they are using. I was being introduced to one of the newer members of the vendor team that I had never met and was asked the following question while describing the work Itential does: “So, when Itential says SDN what do you mean?” At first I was taken aback because this is a vendor that is a pretty major player in the SDN space, and my initial reaction was to think he didn’t understand what SDN was….

The Current State of NFV: Standards

By | Blog | No Comments

There are two standards out there right now that have strong momentum. One being the ETSI NFV standard that has been around for quite a while, and the other being the recently open sourced Enhanced Control, Orchestration, Management and Policy (ECOMP) architecture from AT&T based on the work done as part of Domain 2.0. ETSI has been the leader in this space, and is the standard that almost everyone is using. It is also a less complicated view of what is required to successfully create and manage an NFV environment. There…

The Current State of NFV: Introduction

By | Blog | No Comments

We are going to be posting a series of blogs over the next few weeks to cover where we see the NFV landscape right now, the issues we see still outstanding, an assessment of the maturity of various layers to the NFV reference architecture (considering both the ETSI NFV and AT&T ECOMP frameworks), and where we see things moving in the future. Itential has spent the last 2 years or so working with clients in a hands-on capacity trialing various tools and solutions for SDN and NFV. We have at a…
