Border Gateway Protocol (BGP)

Border Gateway Protocol (BGP) is a key protocol that helps determine the best paths for data to travel across the internet. Think of it as a postal service that decides the most efficient routes for sending mail between different cities, which in this case are networks. BGP enables different networks to communicate with each other, sharing information about available routes and their reliability. By doing so, it ensures that data packets reach their intended destinations efficiently and reliably, even if some routes are congested or down. BGP plays a crucial role in maintaining the stability and functionality of the internet.
