What Internet Backbone?
December 15th, 2008
The internet was designed to be decentralized, error-tolerant, and highly variable in how it could route packets from one computer to another. According to Wikipedia, the “internet backbone” is “made up of a large collection of interconnected commercial, government, academic and other high-capacity data routes and core routers that carry data across the countries, continents and oceans of the world.” The internet doesn’t have a backbone in the traditional sense; rather, it’s more like a spider web. Many of the connections referenced in the Wikipedia definition are between major service providers who have cooperative agreements (I’ll carry your traffic if you’ll carry mine). The linked article explains what happens when one of those agreements breaks down, and gives insight into just how fragile the internet can be.
