What does BGP stand for?

BGP stands for Border Gateway Protocol. It is a standardized exterior gateway protocol that is used to exchange routing information between different autonomous systems on the internet. BGP is crucial for determining the best paths for data transmission, which ensures efficient and reliable routing between large networks.

The protocol operates using a system of attributes that determine the best routes. It is particularly important because it handles the inter-domain routing that allows the internet to maintain connectivity between disparate networks. BGP is essential for the stability and scalability of the internet, making it one of the foundational protocols for the routing infrastructure.

The other options do not correctly represent what BGP stands for, as they refer to different concepts or are not established protocols in networking.
