What is BGP Routing and Why is It Important?

BGP is the primary routing mechanism used today to route packets over the internet, making it a very important routing protocol to understand. In the simplest terms, BGP Routing can be thought of as GPS for packets traversing the internet. As packets are sent across the internet, it’s BGP that assesses the fastest, most efficient path that data packets can take and facilitates this packet transfer in the most speed-optimized manner possible.

BGP accomplishes this data transfer optimization through analyzing what are called Autonomous Systems or AS. To refer back to our GPS analogy, you can think of Autonomous Systems as different streets in a neighborhood, where many different houses reside on those streets. You can imagine, without good GPS, you may traverse an unoptimized path to finally stumble upon the house you're looking for. With GPS or BGP Routing, this routing mechanism will provide the shortest path by assessing the various routes associated with traversing different Autonomous Systems. BGP Routing is what allows us to traverse the internet today with the speed and scale required by modern society; without it, it could take much, much longer to use the internet for even the simplest task.
