BGP is the only inter-autonomous system routing protocol, so it is the protocol that makes internet work. Border Gateway protocol enables internet service providers(ISPs) to establish routing among each other and maintain the global reachability. BGP uses an algorithm which cannot be classified as a pure "Distance Vector", or pure "Link State". It is a path vector routing protocol as it defines a route as a collection of a number of AS that is passes through from source AS to destination AS. This list of ASes are called AS_PATH and is used to avoid eBGP routing loop. The performance of Global Routing System is very important for all the entities operating the autonomous systems, which makes up the internet.
