Enabling The Future Network Through Automation

By | Blog | No Comments

In a recent keynote Marcus Weldon (Bell Labs President and Nokia CTO) and Vint Cerf (ForMemRS) put forth the idea that IoT is going to have such a profound impact on the world that it could essentially dissolve country boundaries. According to comments on this keynote by Keri Kukral (CEO & Founder at Raw Science), who was in attendance, “Humans care about 150 people in close proximity. Tribal lines could dissolve and become local based on network.” This is pretty Earth-shaking stuff based on how we think of our world right now. This…

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…

Hype Machine: NFV/SDN Versus Automation – Are They The Same Thing?

By | Blog | No Comments

Before I waste any time let me go ahead and answer the question in the title with a resounding NO…now let’s get into why that is the case. A recent Light Reading article on the “cost of automation” says, “…automation is the end game for virtualizing network infrastructure and services using NFV and SDN.” While the article doesn’t outright say it, it pretty strongly implies that the way to automate your network is to virtualize it. The problem with this mindset is that virtualization in and of itself does nothing…absolutely…

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…

Quantum NFV: The Future Is Closer Than You May Think

By | Blog | No Comments

I am constantly thinking about just how network functions are going to become virtualized effectively enough to impact carrier transport networks, where you see the need for very large bandwidth circuits. The current state of virtualized network functions (VNF) is such that you wouldn’t even consider going down this path due to the limitations that exist today. The coming containerization of VNFs is not going to fix this issue either. What might fix it? Well, believe it or not, quantum computing. Before we decide I have gone off the deep…

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…

How Much Wind Is In The NFV Sails?

By | Blog | No Comments

An interesting article recently on Light Reading talked about whether NFV is “in the doldrums” or not. It is a really good read, and I think a lot of what I had been talking about in the state of NFV blogs refers to just this question. There has been a ton of hype about NFV, and people are getting frustrated with the lack of results that have occurred. This is because of the general lack of maturity in the tooling around NFV that will allow it to realize all of…

Operational Challenges Abound, and Not Always Tech Related

By | Blog | No Comments

This is a topic I have written on a while back, but it is so important it seemed to deserve a revisit, with a slightly different view than I approached it from before. In the last few weeks we have been discussing with a client this very issue. This client is nearing the launch of a production trial of their NFV environment with a small group of friendly customers. We have worked with them on processes, the issues they can expect to see, and what they should do if/when each of…

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…
