The following is a technical SWOT analysis for Network Engineers, Security Engineers, and Senior Technicians. I apologize for the high number of acronyms used below, but hey, this is networking! In networking, Zero-Trust is not a single product or control. It’s an architecture and operating model where no network location (LAN, WAN, data center VLAN, […]

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
