Backbone

The Internet backbone refers to the main "trunk" connections of the Internet. It 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 resilience of the Internet is due to its core architectural feature of storing as little as possible network state in the network elements and rather relying on the endpoints of communication to handle most of the processing to ensure data integrity, reliability, and authentication. In addition, the great degree of redundancy of today's network links and sophisticated real-time routing protocols provide alternate paths of communications for load balancing and congestion avoidance.
