3.7.1 Overview
7705 SAR QoS policies are applied on service ingress, service egress, and network
interfaces. The service ingress and service egress points may be considered as the
network QoS boundaries for the service being provided.
The QoS policies define:
• classification rules for how traffic is mapped to forwarding classes
• how forwarding classes are aggregated under queues
• the queue parameters used for policing, shaping, and buffer allocation
• QoS marking/interpretation
There are several types of QoS policies (see Table 18 for summaries and references
to details):
• service ingress (also known as access ingress)
• service egress (also known as access egress)
• MC-MLPPP SAP egress
