Exterior Gateway Protocols (EGP)

Exterior Gateway Protocols (EGPs) are systems used to connect different internet networks, known as autonomous systems, ensuring they can communicate and exchange routing information. They help manage how data travels across separate networks, directing traffic efficiently and reliably. The most common EGP is BGP (Border Gateway Protocol), which enables various organizations' networks to exchange routing information and maintain the overall stability and integrity of the internet. Essentially, EGPs act as the traffic controllers at the borders between large internet domains, coordinating data flow across complex, interconnected networks.
