This object identifies the queuing discipline that is associated with the specified queue. Several general purpose and well-known queuing disciplines are supported by this attribute. Queuing disciplines that differ from those that are supported by this object are specified by setting this attribute to other(1) and providing the object identifier that represents the different queuing paradigm in the qosIfQueueExtDiscipline object.

A value of fifo(2) indicates that the queue is serviced on a first-in-first-out (FIFO) basis. This discipline is generally employed when only a single queue is available for a given interface.

A value of pq(3) indicates that the queue is serviced using a priority queuing discipline. This technique is used when several queues are available for a given interface. Each queue is assigned a priority and queues are serviced in order of priority. Higher priority queues are completely drained before lower priority queues are serviced.

A value of fq(4) indicates that the queue is serviced using a fair queuing discipline. This technique is used when several queues are available for a given interface. Each queue is treated equally and is serviced in a round-robin fashion.

A value of wfq(5) indicates that the queue is serviced using a weighted fair queuing discipline. This technique is used when several queues are available for a given interface. Each queue is serviced based on queue weights which determine the scheduling and frequency of queue servicing. Queues that are assigned a greater weight are implicitly provided with more bandwidth.

Note that the processing disciplines for all of the queues in a given set must be considered when trying to establish a processing profile for a given interface.
