Network Qos Policies - Alcatel-Lucent 7950 Quality Of Service Manual

Network QoS Policies

Network QoS policies define egress QoS marking and ingress QoS interpretation for traffic on
core network IP interfaces. The router automatically creates egress queues for each of the
forwarding classes on network IP interfaces.
A network QoS policy defines both the ingress and egress handling of QoS on the IP interface.
The following functions are defined.
•

The default network QoS policy is applied to all network interfaces which do not have another
network QoS policy explicitly assigned.
