Intent-Primarily based Networking for Dummies writer Jeff Doyle discusses why IBN, the autonomous, self-provisioning paradigm designed to make community administration simpler, is the logical evolution of SDN.
The primary purpose corporations create content material like ebooks, white papers, and weblog posts about their services or products is to promote extra of that services or products. That is logical and comprehensible since promoting extra stuff is why advertising, together with content material advertising, exists.
Corporations additionally need to showcase their experience to potential prospects. That is the place conventional advertising and content material advertising (the world of selling that offers with book creation) diverge. In its easiest kind, conventional advertising is all about promoting the sizzle, whereas content material advertising is about showcasing the substance. In reviewing the brand new intent-based networking (IBN) book from Apstra, I discovered myself going into the undertaking responsible of the previous and got here away targeted on the latter.

Intent-Primarily based Networking for Dummies opens by making the enterprise and operational case for why IBN is the subsequent development in information heart networking: Company networks are as distinctive as snowflakes, and they’re saved working by the exhausting work and tribal data of some (or a couple of hundred) devoted engineers and community admins.
From there the book does a pleasant job of laying out the basics of IBN for individuals who perceive networking however have by no means hung out within the trenches working cables or troubleshooting damaged router hyperlinks. It covers the fundamentals of what IBN is and the challenges it addresses, after which supplies good analogies (like flying a airplane on autopilot) that makes IBN extra approachable.
Regardless that the book is written by uber networking guru Jeff Doyle, whose different works embody the two,000 web page tome CCIE Skilled Growth: Routing TCP/IP, Quantity I and II, it doesn’t get mired down within the technical weeds of IBN. Somewhat, it addresses IBN additional up the stack with sufficient high-level technical element in order that it is going to be attention-grabbing to community engineers however accessible to CIOs as effectively.
As a substitute of merely rehashing what’s within the e book, I interviewed Doyle, who’s at present working with Apstra as a member of its technical group to higher perceive why IBN is and is not the “subsequent massive factor” in networking.

TechRepublic: Conceptually, the thought of with the ability to run networks on autopilot sounds very interesting. Does that make IBN the subsequent massive development in networking?
Jeff Doyle: I’d say that IBN just isn’t the newer, better development. It is really a part of a continuum of what is going on on in networking that basically form of began with SDN [software defined networking]. Regardless of the working joke proper now that SDN stands for ‘nonetheless does nothing,’ I’d disagree. Though I prefer to joke, information facilities want that management layer somewhat than making an attempt to handle particular person nodes. What’s actually necessary that comes out of SDN is the thought of seeing the community as a single entity. Principally, abstracting the community out of what is bodily there.
Folks form of need to see [IBN] as, ‘Oh, you are simply one other automation platform, otherwise you’re simply configuration administration, otherwise you’re just a few form of a telemetry monitoring software.’ All these kinds of issues are all items of it, however IBN form of turns into the cerebral cortex on high of the lizard mind, which has all these different capabilities. It is simply including this intelligence to the community.
TechRepublic: What’s driving the development in direction of extra community autonomy?
Doyle: Networks have gotten very advanced. And it is not simply the success versus intent… It is also , ‘Okay, if I inform the community to do one thing, how is that going to have an effect on all the pieces else in my community?’ I’ve bought sure providers working. There’s the consideration of how advanced is it to deploy? What are the insurance policies that I would like to contemplate? How does it have an effect on what I have already got in my community? Am I going to harm my current latency? Am I going to overwhelm sure switches? Am I going to trigger TCAM issues in a few of my switches?
That is a variety of very advanced issues as a result of networks are advanced and that is what intent-based networking does is maintain all these configurations. So, whenever you say, ‘I need to do that’ [IBN] software program comes again to you and says, ‘Maybe you do not have the sources right here, or that is how it’ll have an effect on what you are doing.’ What I take into account the larger a part of that’s after getting established what your intent is for some expertise in your community, IBN continues to watch that.
TechRepublic: When folks consider networking, they’re typically targeted on the final mile, connecting gadgets like smartphones, printers, card readers, cameras, and many others. to the company WAN. Is connecting these kinds of gadgets what IBN is all about?
Doyle: It is extra making ready the community for no matter [you want to do]. For those who have a look at card readers and cameras and all these sorts of issues, when you consider all these as purposes, which they’re, in some unspecified time in the future they use the community. What IBN is doing just isn’t essentially coping with these purposes themselves, however wanting on the software necessities for the community and setting the community accordingly to have the ability to assist these efforts.
I have been in consulting because the ’80s. It looks like each engineer can have their very own concept of what is one of the best ways to implement issues. You find yourself with networks the place particular person gadgets are configured in another way and insurance policies are configured in another way, protocols are configured in another way… since you’ve had a variety of totally different fingers within the pie.
That is one of many benefits of IBN. IBN is saying, ‘That is the perfect observe, the best way to configure no matter it’s you might be desirous to do along with your community. And… it is carried out precisely the identical approach. So, your entire gadgets ought to look the identical.”
TechRepublic: How a lot AI is concerned? This seems like a expertise that would lean closely on AI.
Doyle: In some methods, and I definitely wouldn’t need to say that that is not going to be a chunk sooner or later. However, for what we’re doing proper now, it is not. We usually steer clear of machine studying.
TechRepublic: What stage are we at within the evolution of IBN at present?
Doyle: For my part, very early days. While you have a look at what the guarantees of IBN are, and that is strictly my very own opinion, in some unspecified time in the future it’s best to have the ability to function your community with out having folks skilled in the entire totally different working programs that go into your community.
