Reducing BGP convergence time by fine tuning the MRAI timer on different topologies

Pradeep, K; Alani, OYK

Abstract

In this paper, we use a discrete event simulator for testing convergence behavior of the only existing inter domain routing protocol BGP. The purpose of this paper is to analyze and understand the convergence behavior of BGP under different network topologies and to fine tune to get better convergence time. OPNET, a discrete event simulator, modular simulation tool that allows simulation of Autonomous System (AS) level topologies is used with varying parameters. The MRAI timer is manipulated and tested on convergence time, and the results are compared with simulations done by similar work in the literature. The effect of different MRAI value was tested on the convergence for different network topologies and we were able to see changes in convergence time. We conclude that MRAI helps in controlling the increase or decrease in the number of updates and the convergence time. However, the tradeoff is between convergence time and end to end traffic loss/delay and BGP traffic.
