Research on BGP-4 Routing Stability

Open publisher page 0 citations

Abstract

The border gateway protocol is the inter-domain routing protocol used to exchange reachability information between autonomous systems in the global Internet. BGP is a path-vector protocol that allows each autonomous system to override distance-based metrics with policy-based metrics when choosing best route. It is possible for a group of autonomous systems to independently define BGP policies that together lead to BGP protocol oscillations that never converge on a stable routing. This paper mainly studies the routing stability of BGP-4 and the corresponding solving technology. ;;
