QoS Doubt

[Arjun Dabol]

While reading QoS i see words being used such as "1P1Q3T" OR "1P7Q3T" or "3Q3T" like in this article below

What exactly is this Ps...Qs...Ts...and why do they have 1 ..3....7..these numbers before them..any high level idea will help so that I can further read.

P = priority queue
Q = normal queue ie. not priority
T = threshold which are used within a queue ie. it allows you to prioritise certain traffic over
other traffic within the same queue.

The numbers are simply the number of queues and/or thresholds per queue.

# = number of whatever feature is listed by letter

P = priority queue

Q = queue

T = drop threshold

e.g.

1P7Q3T = one priority queue, seven ordinary queues, three drop thresholds
