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….

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…

So What’s Up With MANO?

By | Blog | No Comments

The Management and Orchestration (MANO) stack in the ETSI NFV model is a place full of interesting, and confusing at times, ideas. Many vendors have very different ways of looking at the functionality provided in that area. For reference, below is the standard ETSI NFV framework, with some of the underlying and surrounding components added: One of the best defined areas within MANO, and most mature, is the Virtual Infrastructure Manager (VIM) component. As such we won’t spend a lot of time on that. OpenStack is the clear leader in this…
