End-to-End QoS Network Design

Chapter 15. MPLS VPN QoS Design

MPLS VPN QoS design typically is viewed from two distinct perspectives:

• The enterprise customer subscribing to the MPLS VPN service

• The service provider provisioning edge and core QoS within the MPLS VPN service

To achieve end-to-end service levels, enterprise and service-provider QoS policies must be consistent and complimentary. Therefore, QoS considerations and design recommendations for both the enterprise and service provider are presented in this chapter. The following topics are discussed:

• Enterprise-to-service provider mapping models

• Service provider-to-enterprise models

• MPLS DiffServ tunneling modes

• DiffServ in the backbone

• MPLS traffic engineering

MPLS is a combination of routing and switching technologies that ...
