BGP

Border Gateway Protocol (BGP) is the system that helps internet networks communicate and share information about how to reach each other. Think of it as a set of rules that small regional networks (ISPs) use to share the best routes for data to travel across the global internet. When you send a message or visit a website, BGP ensures your data finds the most efficient path through various networks. It helps keep the internet connected, reliable, and responsive by constantly updating the best routes based on network conditions.
