Applying QoS to an MPLS Network Model

Differential Services (DiffServ) extensions can be used to apply quality-of-service constraints to your MPLS network model. To do this, you must configure QoS do the following:

•Specify traffic classes in the MPLS configuration object

•Adjust DSCP settings in the QoS configuration object

•Configure queuing schemes and profiles on the affected routers

To use different traffic classes in your MPLS network, you must first specify separate traffic trunks for the different classes in the MPLS configuration object. To do this, use Procedure 6-5 on page SPM-6-16to create a default traffic trunk. However, instead of setting the Trunk Details attribute to Default, double-click to set the traffic profile, out-of-profile actions, and traffic class of each trunk.

To configure quality-of-service parameters, edit the Priority Queuing Profiles ➘ DSCP Based attribute in the QoS configuration object.

Finally, you must configure the affected routers to use the correct queueing scheme and queuing profile.

Procedure 6-9 Configuring the Queuing Stream and Profile of a Router

1Set the Queuing Scheme attribute (IP Routing Parameters ➘ Interface Information ➘ QoS Information)

2Set the Queuing Profile attribute to DSCP Based.

End of Procedure 6-9
