Multi-Path Inter-Domain Routing: The Impact on BGP's Scalability, Stability, and Resilience to Link Failures

Multi-path routing protocols are proposed to solve transient disconnectivity during convergence time. As their name implies, these protocols are designed to explore more paths than BGP in the attempt to keep the ASes connected in case of link failures. The impact of the multi-path routing protocols on scalability, stability, and resilience to link failures are studied using simulation experiments.
