BGP (Border Gateway Protocol)

Border Gateway Protocol (BGP) is the protocol that determines the best routes for data transmission on the internet by exchanging routing and reachability information among autonomous systems (AS). BGP is crucial for the functioning of the Internet, as it determines the best routes for data transmission across different networks. It enables different parts of the Internet, known as autonomous systems—such as those belonging to ISPs, businesses, or universities—to communicate and exchange routing information, ensuring that data packets find the most efficient path to their destination.
