Intent-based Networking author for Dummies Jeff Doyle discusses why IBN, the autonomous automation paradigm designed to make network management easier, is a logical evolution of SDN.

The main reason companies create content such as e-books, white papers, and blog posts about their products or services is to sell more of that product or service. This is logical and understandable because more marketing is the reason why marketing, including content marketing, takes place.

Companies also want to showcase their knowledge to potential customers. This is where traditional marketing and content marketing (the area of ​​marketing that deals with ebook creation) differ. In its simplest form, traditional marketing is about selling the sizzle, while content marketing is about showcasing the stuff. In reviewing the new intent-based network book (IBN) from Apstra, I found myself getting into the guilty project of the last one and came away with a focus on the last one.

Mission-based networking for dummies opens by making the business and action case for why IBN is the next trend in data center networking: Corporate networks are as unique as an avalanche, and are kept up and running hard and a few (or a few hundred) consecrated tribal knowledge. network engineers and administrators.

From there the ebook does a great job in laying out the basics of IBN for people who understand networking but have never spent time in the trenches running cables or troubleshooting broken connections router. It covers the basics of what IBN is and the challenges it faces, and then provides good analogies (such as airplane flight on autopilot) that make IBN easier to talk to.

Even though the ebook is written by uber network guru Jeff Doyle, whose other works include the 2,000 tome page CCIE Professional Development: TCP / IP Pathway, Books I and II, it is not damaged in IBN technical plants. Instead, it handles IBN further up the stack with high-level technical detail enough to be of interest to network engineers but accessible to CIOs as well.

Instead of just repeating what is in the book, I interviewed Doyle, who is currently working with Apstra as a member of its technical team to better understand why IBN is and is not the “Next big thing” in networking.

TechRepublic: Conceptually, the idea of ​​being able to run networks on autopilot feels very appealing. Does that leave IBN as the next big shift in networking?

Jeff Doyle: I'd say IBN isn't the latest trend, either. It's really part of what's going on in networking that really started with SDN [software defined networking]. Despite the current running joke that SDN stands for 'still doing nothing,' I do not agree. While I like to joke, data centers need that level of control rather than trying to control individual nodes. The key to SDN is the idea of ​​seeing the network as one organization. Basically, remove the network from what is physically present.

Kind of people want to see [IBN] like, 'Oh, you're just another automation platform, or you're just a configuration guide, or you're just some kind of telemetry monitoring application.' All of these things are parts of it, but the IBN type is going to be the cerebral cortex as well as the lizard brain, which has all these other functions. It just adds this information to the network.

TechRepublic: What is driving the move toward greater network autonomy?

Doyle: Networks are becoming very complex. And it's not just a performance against a mission ... It also looks at, 'Okay, if I ask the network to do something, how will that affect everyone? anything else in my network? ' I have special services running. Considering how complex it is to use? What policies do I need to consider? How does it affect what I already have on my network? Am I going to hurt my long time? Do I get over certain switches? Am I going to cause TCAM problems in some of my switches?

That's a lot of complicated issues because networks are complex and that's what purpose - based networking is all about looking at all of those configurations. So when you say, 'I want to do this' [IBN] software will come back to you and say, 'You may not have the resources here, or this may affect how you do it.' What I think is the biggest part of that is that once you have figured out what your intention is for some technology in your network, IBN continues continue to monitor that.

TechRepublic: When people think of networking, they often focus on the last mile, connecting devices such as smartphones, printers, card readers, cameras, etc. to the physical WAN. Is IBN all about connecting those kind of devices?

Doyle: It further prepares the network for whatever [you want to do]. If you look at card readers and cameras and all sorts of things, if you think of everyone as applications, who they are, they will use the network at some point. What IBN is doing is not necessarily addressing these applications themselves, but looking at the application requirements of the network and positioning the network accordingly to be able to support the applications. those efforts.

I have been in consultation since the 80s. Every engineer is likely to have their own idea of ​​how best to implement things. You will have networks where individual devices are configured differently and policies are configured differently, protocols are configured differently ... because there are a lot of different branches. different in having in the piece.

That is one of the advantages of IBN. IBN says, 'This is best practice, how you configure whatever you want to do with your network. And… it is implemented in the same way. So all your devices should look the same. ”

TechRepublic: What level of AI is involved? This is like a technology that can put a lot of pressure on AI.

Doyle: In some ways, and I certainly would not want to say that that is not going to be a piece in the future. However, for what we are doing now, no. We usually stay away from machine learning.

TechRepublic: At what stage are we in the evolution of IBN today?

Doyle: In my opinion, very early days. When you look at the promises of IBN, and that is just my opinion, at some point you should be able to operate your network without people being trained in all systems. different operations that enter your network.
