Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet.

- Border Gateway Protocol

First, AS-level paths are selected via the BGP protocol that produces a sequence of ASs through which packets flow.

An autonomous system (AS) is a collection of connected Internet Protocol (IP) routing prefixes under the control of one or more network operators on behalf of a single administrative entity or domain, that presents a common and clearly defined routing policy to the Internet.

Each AS is assigned an autonomous system number (ASN), for use in Border Gateway Protocol (BGP) routing.
