An Experimental Analysis of BGP Convergence Time
The Border Gateway Protocol (BGP) is the routing protocol used to maintain connectivity between autonomous systems in the Internet. Empirical measurements have shown that there can be considerable delay in BGP convergence after routing changes. One contributing factor in this delay is a BGP-specific timer used to limit the rate at which routing messages are transmitted. We use the SSFNet simula...
متن کاملDestination Reachability and BGP Convergence Time
One important performance measure for routing protocols is packet delivery. An ideal routing protocol should quickly adapt to topological changes and deliver packets as long as any path to the destination exists. In this paper, we examine the packet delivery performance in a network running the BGP routing protocol when a destination may be disconnected from time to time. We develop two metrics...
متن کاملReal-time Model and Convergence Time of BGP
BGP allows routers to use general preference policies for route selection. This paper studies the impact of these policies on convergence time. We first describe a real-time model of BGP. We then state and prove a general theorem providing an upper bound on convergence time. Finally, we show how to the use the theorem to prove convergence and estimate convergence time in three case studies.
متن کاملSimulating convergence properties of BGP
We present a simple BGP simulator that is used for testing convergence properties of inter-domain routing. The discrete-event driven simulator contains a high-level abstraction model of the BGP protocol. The purpose is to perform simulations to examine the complexity of routing information exchange and to test different possible reasons for delayed convergence of BGP routing. We have simulated ...
متن کاملBGP-RCN: improving BGP convergence through root cause notification
This paper presents a new mechanism, called BGP with root cause notification (BGP-RCN), that provides an upper bound of O(d) on routing convergence delay for BGP, where d is the network diameter as measured by the number of AS hops. BGP-RCN lets each routing update message carry the information about the specific cause which triggered the update message. Once a node v receives the first update ...
