I recently received an email requesting my thoughts on the top ten books for broadband technicians to have in their possession or library. Great question. After some thought, here are my top ten (in no particular order) recommended books and handbooks for broadband / fiber / telecom technicians. These cover theory, practice, installation, troubleshooting, standards, […]

MPLS (Multiprotocol Label Switching) is often regarded as one of the most elegant service provider networking technologies after TCP/IP itself because it solved several big problems introduced in the late 1990s (and I got to be part of that): For service providers, this was game-changing. Many argue that without MPLS, the explosion of managed VPNs,

In Networking we have always used a Layered Model to represent and apply network functions and protocols and their relationships to one another. Whether you like 7 layers or 4 layers is all wasted argument to me. I am a packet guy, and in the packets the protocols are layered. Any manipulation of this either

In this post, I want to document the fundamental algorithms built into TCP. Keep in mind that these have changed over time in an attempt to make TCP more effective with faster and larger capacity connections of todays Internet. See our post on TCP “versions” here. TCP uses several key algorithms to manage connection setup/teardown,
Moore’s Law is an observation made by Gordon E. Moore, co-founder of Intel, in 1965. He noted that: The number of transistors on a microchip doubles approximately every two years, while the cost of computers is halved. This effectively meant exponential growth in computing power and a decrease in relative cost over time. So where

Ever wonder what it takes to network an industry showcase like ShowNet? ShowNet is a large-scale demonstration network built annually since 1994. It showcases cutting-edge networking technologies and provides stable internet connectivity throughout the exhibition floor. Over 400 engineers from academia and industry collaborate to design, deploy, and operate this network, utilizing over $80 million

Teaching hexadecimal and binary, especially around bits, nibbles, and bytes, is an awesome way to introduce kids to how computers “think.” Let’s face it their world is fully computerized and networked. All communications is done in binary, bits, nibbles, and bytes. Heck, its the way computers think. Here is a deeper dive into why kids

Teaching kids about networking (the digital kind, not social networking) can actually be a lot of fun if you break it down into simple, relatable concepts and use interactive activities. I have written other articles like teaching kids programming and teaching kids electricity. Here I want to talk about networking. Here’s a step-by-step approach to

I previously posted an article on teaching kids electricity with Squishy Circuits, as well as teaching kids about networks/networking, and someone asked what about programming. Great question. Back in the day (2005) there was a special computer (the XO) you could buy that was tuned to kids learning programming. It was called the One Laptop

As a follow on to my article on whether AI can be used in Networking, this post dives in deeper to a question of will humans still be involved? And if so, how do we upskill that human expertise? To successfully integrate AI into network automation while ensuring human expertise is maintained, organizations and IT

Cisco had a free self paced, online learning course – until March 24th, 2025! I don’t know if it is still available – I think they are charging now. The course is called: AI Solutions on Cisco Infrastructure Essentials | DCAIE. Learn about the essentials of deploying, migrating, and operating AI solutions on Cisco data center infrastructure.

Before I provide the example, let’s be straight up about AI. Relying on AI for everything is problematic because it diminishes human critical thinking, introduces biases, and creates dependency on automation that may not always be reliable. While AI excels at processing vast amounts of data and automating tasks, it lacks intuition, ethical reasoning, and

As a hands-on technical author and instructor, I have been wondering if AI could possibly replace me. OK, perhaps not replace me, but instead enhance the training I have been providing for decades. I have discussed this with a number of others both on the instructional side and on the student side. From these discussions,

A recent discussion with several colleagues led to a discussion on how AI can be leveraged in the world of internetworking. With all the hype around AI, some pretty crazy things are being claimed by vendors, but looking under the surface requires specific solutions and, frankly, things become very vendor specific very quickly. I chose
