BGP means Border Gateway Protocol. It is a standardized exterior gateway protocol which
can exchange routing and reachability information between autonomous systems (AS) on
Internet.
The protocol TCP is used by two routers supporting BGP for data transmission. They can
exchange the BGP routing information for each other. A BGP router is the “neighbor” of
other BGP routers. Define the IP address, AS number for the router is essential for TCP
connection of BGP routing information exchange.
AS, the abbreviation of Autonomous System, is a group interconnected with multiple IP
addresses. AS numbers indicate the full paths that the route information will be taken. It can
be operated by one or several ISPs and follows the routing policies made by ISP.
