Abstract

Multiprotocol Label Switching possesses a simple data-plane that has enabled new services and functions operating in many service provider networks. Yet,the MPLS control plane can impose both technical and operational challenges. This article explores these challenges and examines recent advances in IP routing technology suggesting that all services—including those that are MPLS-based—can be delivered over networks running only IP.
