Mapping ABR to TCP Congestion Control and QUIC
Post Views: 31 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
What Is Adaptive Bitrate Streaming (ABR)?
Post Views: 95 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
A Synthetic ABR Lab Exercise
Post Views: 90 The following is a step by step lab exercise to examine ABR – Adaptive Bit Rate used in modern video content delivery. I won’t explain ABR here – you can read about ABR and what it is, and how it works here in a recent post. We will analyze a synthetic but
What is TCP CUBIC and Why so popular?
Post Views: 175 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
Create your own Wireshark Labs with AI
Post Views: 1,052 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

Why don’t you employ the “click” model on your sites?
Post Views: 965 This is a great question recently asked by one of our students/clients when we said our usual introductory comments that “No we won’t spam you”, and “No we don’t use the click model on our sites”. Now most of you know, we are a small family business, and have been since day
Zero-Trust Networking & Converged Security
Post Views: 1,307 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,
