Chapter 8. MPLS Quality of Service

This chapter covers the following topics:

  • Quality of Service—. Service providers that offer IP services over an MPLS backbone must support IP quality of Service (QoS) over their MPLS infrastructure. This means supporting IP QoS over MPLS VPNs or MPLS traffic-engineered paths. MPLS can help service providers offer IP QoS services more efficiently over a wider range of platforms, such as ATM LSRs.

  • Integrated Services—. Integrated Services (IntServ) refers to an overall QoS architecture developed by the Internet Engineering Task Force (IETF). IntServ specifies a number of service classes designed to meet the needs of different application types. IntServ also specifies various signaling protocols.

  • IP Precedence—.
