6.1 MPLS QoS Overview

The QoS solution for MPLS mainly completes the following functions:
Classify the service traffic on CE or PE according to specific needs, for example, into
three types: voice, video and data.
When PE adds a Label to the packet, it will map the IP precedence flag carried by the IP
packet to the CoS domain of the flag, and thus the class information carried by IP is
carried by the flag now.
Among the PE routers, the differentiated dispatching (such as PQ, WFQ, and CBQ) is
performed, that is, transmit the service traffic with flag on a LSP in the mode of
differentiated QoS.
Note:
To understand the contents in this chapter, you should have some background
knowledge related to MPLS. Refer to "MPLS Configuration" in this manual for the
description of MPLS basic concepts and related configurations. This chapter only
involves MPLS QoS configuration.

6.2 MPLS QoS Configuration

To configure MPLS QoS, you should first perform the related configuration of MPLS
and specify to display the route forwarding mode. For detailed configurations of MPLS,
refer to "MPLS Configuration" in this manual. This chapter only describes MPLS QoS
configuration.
MPLS QoS configuration includes:
MPLS PQ
MPLS CQ
MPLS CBQ
MPLS CAR
The following describes the method of configuration for each of the above in detail.
