Post Views: 1,531 I have seen a bunch of posts about IP version 8 supplanting IPv6. Let’s sort this out a bit. I think a full listing of the IP version numbers is needed as a backdrop. The Internet Protocol (IP) has evolved through a sequence of versions during its research, testing, and operational deployment […]

Post Views: 977 Net neutrality in the United States has evolved through a cycle of regulatory assertion, legal limitation, reclassification, repeal, and attempted reinstatement. It is not a fixed policy but a dynamic framework shaped by the intersection of law, politics, and network engineering realities. At its core, the debate reflects a fundamental tension. On

Post Views: 775 I described what Adaptive Bit Rate Streaming (ABR) is in my prior article, if you need that background. Also there is an ABR Lab Exercise if you want some hands on learning with ABR that will show you visually some of the items discussed below. Here, I wanted to dive a little

Post Views: 739 Adaptive Bitrate Streaming (ABR) is a video delivery method that dynamically adjusts the quality of a stream in real time based on three things: network conditions, device capability, and player performance. Instead of delivering a single fixed-quality, and therefore fixed transfer rate video, ABR continuously selects the most appropriate bitrate to maintain

Post Views: 1,550 Most people do not know this, but TCP CUBIC is the dominant congestion control algorithm used in modern TCP/IP networks. It is designed to efficiently utilize high-speed, long-distance links while maintaining fairness across flows with different round-trip times (RTTs). Today, it is the default congestion control algorithm in most Linux systems, and

Post Views: 1,601 I 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

Post Views: 1,597 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,

Post Views: 1,272 What I have created here is a somewhat technical SWOT Analysis for Network Engineers and Technicians for one of today’s top networking subjects of interest: the high speed needs being delivered by Ethernet technology for AI and for Data Centers. Introduction: Why High-Speed Ethernet Matters in AI Infrastructure High-Speed Ethernet has become

Post Views: 674 A SWOT analysis is a structured analytical framework used to evaluate a subject from four complementary perspectives: Strengths, Weaknesses, Opportunities, and Threats. We have been providing SWOT analyses for our clients since our inception. You can read more about that service here. For now, however, let’s simplify and explain what a SWOT

Post Views: 5,278 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,

Post Views: 2,154 Let’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

Post Views: 3,276 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

Post Views: 2,500 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

Post Views: 2,548 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
