The weight specifies the priority of the queue during scheduling up to its CIR.

The weight specifies the priority of the queue during scheduling above-CIR, up to its PIR.

The weight is used to determine how this queue and other queues or schedulers at the same CIR-level share available CIR bandwidth at that level.

All out-of-profile traffic will be dropped before any in-profile is dropped.

The time average factor of 0 will discard all packets arriving in the shared buffer pool.

When the shared buffer utilization reaches 51%, in-profile packets might be dropped.

The highest probability with which an out-of-profile packet can be dropped is 20%.

When an in-profile packet arrives and the shared buffer utilization is at 69%, the packet will have approximately a 60% likelihood of being discarded.

When using profile-mode queues, traffic that is marked as in-profile on ingress and scheduled in the above-CIR loop will still be considered as in-profile at egress.

When an HQoS strategy using an egress port-scheduler has been deployed, Tier 1 receives its scheduling rates based on the amount of egress bandwidth available for each forwarding class.

The greater the difference between PIR and CIR rates in a queue, the less likely a CIR will be provided.

Packets scheduled out of high-priority queues in the default scheduler will have a lower chance of packet loss at the expense of incurring a higher probability of delay.

When using priority-mode queues, traffic that is marked as in-profile on ingress and scheduled in the above-CIR loop will be considered as in-profile at egress.

IntServ uses a protocol like RSVP to provide QoS guarantees on a per-flow basis.

DiffServ groups multiple microflows into bigger streams called macro flows.

Intserv requires that network routers allocate resources for thousands of individual flows.

Diffserv classifies packets into forwarding classes only at the first network hop.

It is the rate at which a traffic stream is offered to a queue.

It is the rate at which packets are forwarded out of a queue.

It is the minimum rate at which packets may be forwarded out of a queue.

It is the maximum rate at which packets may be forwarded out of a queue.
