You can use class of service (CoS) within MPLS networks to prioritize certain types of
traffic during periods of congestion. The CoS value is included within the MPLS label,
which is passed through the network, enabling end-to-end CoS across the network.
MPLS services are often used to ensure better performance for low-latency applications
such as VoIP and other business-critical functions. These applications place specific
demands on a network for successful transmission. CoS gives you the ability to control
the mix of bandwidth, delay, jitter, and packet loss while taking advantage of the MPLS
labeling mechanism.
This example shows how to configure CoS on an MPLS network that is using a
unidirectional circuit cross-connect (CCC) from the ingress provider edge (PE) switch to
the egress PE switch. for the customer-edge interface of the ingress provider edge (PE)
