Sometimes service providers take different approaches to dealing with packet drops on their core routers. One such approach is to carefully monitoring link-utilization rates and adding additional links when utilization rates hit 40 percent to 50 percent, thus obviating the need for QoS. Another approach is implementing MPLS Traffic Engineering. Nonetheless, for providers implementing differentiated services (DiffServ) QoS policies, Figure 34-1 illustrates the specific QoS roles required on SP core routers. ...
