Views: 2,746I have been teaching Wireshark classes since the early 2000’s, and using it since it was called Ethereal. My usage has primarily focused around troubleshooting network issues that have a packet capture associated with them. My fellow troubleshooters will tell you that this is not always the case. But, if we are lucky to

Views: 2,169The 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

Views: 2,236Well, the title “The Story of Secretly Applying ISD in Courses Here” is a little misleading. I have never denied it. Some people have recognized it. I just never made a big deal of it. So let me explain. First, what is ISD? Well, a gentleman named Harold Stolovitch, along with his longtime collaborator

Views: 6,420I 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,

Views: 2,993Let’s just start right out and say: contrary to the scare tactics made by some, that MPLS traffic has been exposed by the providers that operate MPLS, there has never been any validated evidence that such a breach has indeed ever occurred, other than some alleged errors in configuration. MPLS operates between L2 and

Views: 3,929MPLS (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

Views: 3,081In 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

Views: 3,447In 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
Views: 1,940Moore’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

Views: 1,364Ever 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

Views: 2,969Teaching 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

Views: 5,678Teaching 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
