MPLS-TE Routing: Adopting a Generic Architecture and Evaluating Various Implementation Approaches

International audienceVarious Multi-Protocol Label Switching-Traffic Engineering (MPLS-TE) Routing Systems have been proposed in the literature to achieve optimization of resources utilization, Quality-of-Service (QoS) and Fast Recovery. This paper proposes a generic architecture for MPLS-TE Routing Systems, which aims to ease the classification and the analysis of these systems. Then this paper defines a set of MPLS-TE classification criteria. The combination of these criteria leads to the identification of main families of MPLS-TE Routing Systems which are finally compared and qualitatively evaluated according to a set of metrics
