Optimized MRAI Timers for Border Gateway Protocol in Large Networks

Abstract

The global routing performance is essential for the services provided by the internet applications on the Internet. Border Gateway Protocol (BGP) is the extensively used routing protocol for the autonomous systems which constructs the internet. The reduction in convergence time is a crucial challenge for BGP. The past studies confirm that the Minimum Route Advertisement Interval (MRAI) decreases the convergence time. However, most of the approaches are focused on finding the optimum MRAI value. The techniques to implement the MRAI timers are less addressed by the researcher in compare to finding the optimum MRAI value. The implementation of reusable MRAI timers for large networks is critical at different load conditions. Therefore, this article presents the novel approach Optimized MRAI timer in a large network which reduces the convergence time. The proposed approach reduces the end-to-end delay, the number of exchanged updates message, and convergence time of BGP events and enhances the number of delivered packets in compare to related techniques.
