- BGP:
- Border Gateway Protocol
Border Gateway Protocol (BGP) is a standardized exterior gateway protocol used to exchange routing information between different autonomous systems on the Internet. An Autonomous System (AS) is a collection of IP networks and routers under the control of a single organization that presents a common routing policy to the internet.
In the context of networking, an Autonomous System is assigned a unique Autonomous System Number (ASN) and is responsible for managing its own routing decisions. It can be thought of as a self-governing entity within the larger Internet infrastructure, allowing organizations to control how their data is routed across the global network. This is particularly important for ensuring efficient data transfer, optimizing traffic flow, and enhancing security by allowing organizations to implement their own policies and practices.
BGP is essential for maintaining the stability and efficiency of Internet routing, as it helps determine the best paths for data transmission between networks. By enabling effective communication between different networks, BGP plays a crucial role in ensuring seamless connectivity across the global Internet.

[...] is the routing protocol of the global Internet, as well as for Service Provider private networks. BGP has expanded upon its original purpose of carrying Internet reachability information, and can now carry routes for Multicast, IPv6, VPNs, and a variety of other data.
