A device that provides no differentiation between customer traffic flows.

A device that classifies and marks customer traffic.

Native IP Packets will not be remarked.

Native IP Packets will be remarked.

Packets associated with a VPRN service on an upstream node will not be remarked.

Packets associated with an ES service on an upstream node will be remarked.

All AF traffic will be marked "in-profile" at the SAP-ingress.

All TCP traffic will be mapped to forwarding class EF.

UDP traffic is placed in queue 3 while ICMP traffic is placed in queue 5.

EF traffic will receive higher scheduling priority than H2 traffic.

Traffic that does not match any of the IP criteria will be placed in queue 3.

Queue 2 in "policer-output-queues," the default queue group used by policers on egress, because there are no queues in the "qg-10" queue-group template.

The local SAP's queue 1, because there is no queue in the "qg-10" queue-group template for EF traffic.

Queue 1 in the "qg-10" queue-group, because it exists by default and all traffic is mapped to it.

EF traffic is dropped because there are no queues in the "qg-10" queue-group template.

A point at which the initial classification of customer traffic occurs.

A point in the network where QoS parameters are discarded in favor of lower-level hardware queuing functions, such as LLI (Link Layer Interleave).
