Brief Evolution of Net Neutrality in the US

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 one side is

What Is Adaptive Bitrate Streaming (ABR)?

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 smooth playback while

What is TCP CUBIC and Why so popular?

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 since most servers

10 Best Books for Broadband Technicians

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 – the Greatest Service Provider Technology of All Time

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,
