Priority Shift On Automation and MANO Spending

By | Blog | No Comments

As people spend less on their networks, we are seeing interesting things happening in the vendor space. We are seeing some vendors pivot away from their original strategy, often a heavy service provider NFV focus, in order to try and kickstart growth. We also see open source consolidation where projects that were considered contenders in the MANO space are merging. This happened with ECOMP and Open-O merging into ONAP, and we are seeing possible signs of even further consolidation with some of the other contenders. We even see vendors that at one time may…

It’s All About Your Use Case…

By | Blog | No Comments

I recently spoke at NANOG 70 in Bellevue, Washington on the topic of vendor hype in the space versus the reality of what we can and can’t do right now with automation. A huge part of my topic was that some of the tooling out there now is just not to a maturity point yet for us to fully realize all that we soon should be able to. However, in my prep work and during conversations with attendees before and after my presentation another extremely important concept became super clear…

Ops Automation: A New Year, Same Old Challenges…With New Answers

By | Blog | No Comments

As we move into a new year some things have become very clear. Some of these are things we have known for a while, some are revelations from working with clients, and some are things we SHOULD have known all along. There are many efforts going on within service providers and enterprises alike at the moment. There is the work to maintain legacy operations and service offerings under the weight of declining, or at best stable, revenue with a constant, and sometimes increasing, cost of maintenance. There is the effort…

The Secret Sauce of NFV? Operations, With A Side Of Automation…

By | Blog | No Comments

This is probably not what a lot of the technology vendors want you to know. They want you to keep thinking that the secret is that new controller they offer, or maybe containerization of their cool new VNF. All of those things, and more, do indeed matter, but they are not what is going to make or break your NFV implementation. An article the other day by Scott Raynovich on SDx Central points this out, and does a pretty good job of backing up the core message we at Itential have been trying to preach…

NFV Induced Operational Complexity and the Absent VNF Supplier Support Myth

By | Blog | No Comments

An article on SDxCentral.com yesterday points out a few major issues facing Service Providers when it comes to NFV and the operational complexities involved. It focuses most attention on the maintenance of VNFs and how the software model will be very different than the traditional, hardware-based model Service Providers are used to. I have to take exception with comments about VNF support from vendors in the following excerpt from the article: “Often, when service providers ask incumbent suppliers for VNFs, suppliers merely produce virtualized versions of existing boxes, writes Aloke Tusnial, VP…

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….

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…

Orchestration, Orchestration Everywhere…What Are We To Do?

By | Blog | No Comments

One of the most overused phrases in the industry is orchestration. This is the case now, it was the case in the past, and it probably will continue to be in the future. It seems to be everyone’s answer to everything. Every vendor that has an “orchestrator” will promise you they can do anything you want, and this is true if you give them enough time and pay them enough money. You can “orchestrate” anything. So what is orchestration and why should you care about it. An orchestrator automates and “arranges”, to…
