BGP (Border Gateway Protocol)

The Border Gateway Protocol (BGP) is a key system that helps the internet function smoothly by determining the best paths for data to travel between different networks. Think of it as a traffic coordinator for data, ensuring it takes the most efficient route across various internet service providers (ISPs). BGP allows these networks to share information about their available paths, which helps in avoiding congestion and ensuring reliable communication. In essence, it keeps the global internet interconnected and efficient, enabling different networks to talk to each other effectively.
