Many users are always asking about how to prioritize the traffic using the Mikrotik RouterOS Hotspot service.
The following method helps to manage the network traffic and customize it the way you want. It also insure to provide the correct service for a specific use in a big network, giving priority for the VIPs, Special users or services in a congested network.
Also, you can use the same method if you want to make sure that heavy users should not keep downloading or uploading files for long period in order to save the rest of available traffic for light users who are looking for good speed for browsing or occasionally access. This can be applied using the burst limit or a combination of minimum and burst limit with priority.
The trick with bandwidth management in Hotspot is to use the Users Profiles, and assign the different type of speeds that is related to a specific group.

The question is, How to do that?

Using the Winbox, in: IP >> Hotspot >> User Profiles >> rate limit:
use the following string: x1k/y1k x2k/y2k x3k/y3k x5/y5 P x6k/y6k

x1k/y1k: Rate (txrate/rxrate i.e 128k/1024k)
x2k/y2k: Burst Rate (i.e 256k/2048k)
x3k/y3k: Burst Threshold (i.e 160k/1280k)
x5/y5: Burst Time (in seconds i.e: 60/60)
Priority: P (use integer from 1-8)
Minimum rate: x6k/y6k (i.e 32k/256k)

for example: 24k/128k 32k/256k 24k/196k 30/30 8 16k/64k

The following example show you what you have to do exactly:

Burst Rate: 32k/256k
Burst Threshold: 24k/196k
Burst Time: 30/30
Priority: 8
Minimum rate: 16k/64k

In Queues table, you can see what happened exactly for the user having the same profile:

Also, you can check the configured priority here:

if you just want to use rate and priority, then use:
Rate, Burst Rate, Burst Priority, Minimum rate.
