The Service Provider you work for wants to deploy CoS functionality on the P routers of the
MPLS core, to provide a complete CoS solution to all customers that purchase services such as
dedicated Internet access, MPLS Layer 3 VPN, and Layer 2 VPN (pseudowire). The design
requirements are:
 The network supports four service queues with equal treatment for
delay, jitter,and packet loss.

one or two treatments.
 The Service Provider manages control traffic, whereas the customers
manage business critical and best effort.
