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-6-16 to 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.
