In this paper, we attempt to understand the benefits of MPLS traffic engineering through a case study. Specifically, we do a comparative study of MPLS traffic engineering in the presence of dynamic constraint-based routing compared to destination-based routing. For this case study, we use a model derived from an actual service provider network. Different control schemes that can be deployable for MPLS traffic engineering are also considered. This case study shows that services can indeed obtain benefits from constraint-based routing and traffic engineering controls.
