Border Gateway Protocol (BGP) is the routing protocol of the internet, used to exchange routes between different networks (Autonomous Systems – ASes). It helps routers decide the best path for data to travel across the internet based on policies and path attributes, not just shortest distance. BGP is essential for internet providers, large enterprises, and data centers to manage traffic efficiently. An Autonomous System (AS) is a collection of IP networks and routers under the control of a single organization that follows a common routing policy. Learn more: https://en.wikipedia.org/wiki/BGP_
