marking function (as the network ingress policy trusts the received marking of the packet based on
the network QoS policy).
At egress, the profile of a packet is only important for egress queue buffering decisions and egress
marking decisions, not for scheduling priority. The egress queue's CIR will determine the dynamic
scheduling priority, but will not affect the packet's ingress determined profile.
Queue Counters
The router maintains counters for queues within the system for granular billing and accounting.
Each queue maintains the following counters:
•
•
•
•
Queue-Types
The expedite, best-effort and auto-expedite queue types are mutually exclusive to each other.
Each defines the method that the system uses to service the queue from a hardware perspective.
While parental virtual schedulers can be defined for the queue, they only enforce how the queue
interacts for bandwidth with other queues associated with the same scheduler hierarchy. An
internal mechanism that provides access rules when the queue is vying for bandwidth with queues
in other virtual schedulers is also needed.
