White Paper Advanced Topics in MPLS-TE Deployment Virtual path capability and the capacity to engineer precise traffic in a core network have driven Multiprotocol Label Switching (MPLS) towards becoming a standard within service provider core networks. This paper introduces MPLS and Traffic Engineering, including a summary of achieving Resiliency with the technology. It also addresses the integration of QoS and MPLS. There is a detailed configuration / topology provided in the Annex section, which serves as a reference. Introduction MPLS technology is key to scalable virtual private networks (VPNs) and end-to-end Motivation for MPLS quality of service (QoS), enabling efficient The explosive growth of the Internet utilization of existing networks to meet presents a serious challenge to service future growth and rapid fault correction of providers and equipment suppliers in terms link and node failure. of
