BGP

Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. BGP is classified as a path-vector routing protocol, and it makes routing decisions based on paths, network policies, or rule-sets configured by a network administrator.

BGP (Border Gateway Protocol) manages how all of our packets are routed across the Internet. It is one of the most powerful and important protocols currently deployed on the ‘net, but it is also incredibly fragile. Devised as a quick fix 30 years ago (without concern for security), BGP is constantly blamed in the news as Internet outages occur worldwide due to misconfigurations by multinational telecommunications conglomerates or hijackings by government actors.

This talk will demystify the misunderstood protocol that is BGP, and explain how entities exchange giant flows of data across the Internet, highlight past misuses, and consider what we may be able to expect in the future.
