Border Gateway Protocol

Also known as: BGP eBGP Exernal Border Gateway Protocol

The Border Gateway Protocol (BGP) is the routing protocol of the Internet, used to route traffic across the Internet. It does this by exchanging routing and connectivity data between Autonomous Systems on the Internet. BGP is the protocol by which dynamic routing decisions are made in the Internet. Neighboring BGP routers exchanging BGP information are called BGP peers. In the case that a peer goes down, BGP will automatically route traffic that was previously advertised by the failed peer to the next shortest route. This means traffic is automatically routed around outages. VNS3 runs BGP on top of its peering mesh network taking advantage of this dynamic routing.
