BGP / Border Gateway Protocol for Not Yet Techies

"Computer Careers: Using the Only Routing Protocol That Can Send Information Across a Network as Big as the Internet"

by Richard Stooker, President Info Ring Press and author of Secrets of Changing to a Computer Career

BGP / Border Gateway Protocol dates back to 1989 and comes from RFC (Request for Comments) 1105, the way new technologies are introduced to the Internet. Internet Service Providers use this to inform each other which IP address goes where. BGP / Border Gateway Protocol is a distance path protocol.

BGP / Border Gateway Protocol is routing protocol that exchanges routing information across the Internet (or any other IP-like network). It is the only protocol that could work on the Internet due to the Net's size. It uses TCP to communicate with port 179.

BGP / Border Gateway Protocol is the only protocol allowing multiple connections to unrelated routing domains, so it gives large businesses flexibility and backup security in accessing the Internet

If one access point to the Internet is down, having this interdomain routing in use gives them a second one to use.

When IP packets of informations are flowing through the network, if they encounter parts of the network that are down, BGP / Border Gateway Protocol recomputes their path to avoid the server or lines that are not working.

BGP / Border Gateway Protocol is also a security technology - it can be used to combat Distributed Denial of Server (DDoS) attacks, where a hacker attempts to bring down a company's server by overwhelming it past its capacity.

Multiprotocol BGP / Border Gateway Protocol is the form to use for networks other than IPv4 (the current technology of most of the Internet, though IPv6 is on its way).
