The Better Network That Lost: Why Token Ring Died

In the 1980s and 1990s, IBM’s Token Ring wasn't just a rival to Ethernet—it was, by almost every engineering metric, the technically superior networking technology. While early Ethernet relied on a chaotic "collision" system (CSMA/CD) that slowed down under heavy traffic, Token Ring offered deterministic performance, zero packet collisions, and bulletproof reliability. In corporate enterprise environments, Token Ring was the gold standard. Yet today, Token Ring is completely dead, and Ethernet powers the entire internet. How did the better technology lose so completely? In this video, we break down the dramatic protocol war that shaped modern networking, exploring how corporate greed, open standards, and the rule of "good enough" tech destroyed IBM’s networking empire. 📌 What You’ll Learn in This Video: The Token Passing Magic: How Token Ring eliminated network collisions using a virtual "talking stick" (and why it was lightyears ahead of early Ethernet). The Collision Nightmare: Why early coax-cable Ethernet struggled under heavy loads and suffered from "broadcast storms." IBM’s Fatal Mistake: How outrageous licensing fees, proprietary hardware costs, and expensive MSAUs (Multistation Access Units) priced Token Ring out of the market. The Rise of Commodity Hardware: How cheap, open-standard Ethernet cards ($50 vs. IBM's $500+) allowed startups and small businesses to build networks for a fraction of the price. The Final Nails in the Coffin: How 10BASE-T twisted-pair cabling, Fast Ethernet (100 Mbps), and network switches permanently eliminated Ethernet's collision problems—surpassing Token Ring in speed, simplicity, and cost. ⏱️ Timestamps: 00:00 - The Forgotten Networking Giant 02:15 - How Token Ring Worked: Zero Collisions 05:30 - Early Ethernet’s Chaotic Flaw (CSMA/CD) 08:45 - The IBM Tax: Why Token Ring Was So Expensive 12:10 - 10BASE-T & The Commodity Revolution 15:40 - Switched Ethernet: The Death Blow 18:25 - The Tech Lesson: Why "Good Enough" Always Wins 💬 Join the Discussion: Did you ever manage a Token Ring network back in the day?
