Hi,

I use a simple queue for QoS. I understood from the diagrams in the Mikrotik documentation that it should equally divide bandwidth per stream and per device. But that doesn't seem to be happening. It works OK to more or less equally distribute bandwidth between different devices. But on any given device it still allows a single application or monopolize the amount of bandwidth to that device. So if I have a large download (not using multiple connections) running on computer A, I can barely connect to any other internet services or even browse the web on that same machine as long as the download is running. Any tips?

Thanks a lot.

maybe can work for you:

make a similar simple queue like that but per stream and put the simple queue you already have (per device) as parent of this new simple queue

Hmm, could you give a bit more detail on how to set that up per stream? Thanks a lot.

Hi
Have you ever optimised your queues?

Thx

2 ways to do some fair use of bandwidth between multiple devices

using pcq queue
using sfq queue
with sfq you will have more a flow based bandwidth distribution than device distribution

with pcq you can have a flow based distribution when classifier use address and port by default uses only address with address classifier you will see device based distribution

always set max-limit at least 5% below your real bandwidth, in this way queue limit will act before your provider limit act queues only act when limit (congestion) is reached

hey,
thx for the quick reply, haven't expected that

May I ask some quick questions (some might be silly but it got a bit late here )

a flow based bandwidth distribution than device distribution

a flow is a connection? A device can own multipole flows, e.g. these three ones simultaneously: browsing, downloading and video call.
Could it even be multiple ones using the same port?
As you say:

with pcq you can have a flow based distribution when classifier use address and port by default uses only address with address classifier you will see device based distribution

that means PCQ - Queues - RouterOS - MikroTik Documentation:

PCQ parameters:
pcq-classifier (dst-address | dst-port | src-address | src-port; default: "") : selection of sub-stream identifiers

always set max-limit at least 5% below your real bandwidth, in this way queue limit will act before your provider limit act queues only act when limit (congestion) is reached

Do you mean the sum of all queues' bandwidth limits?
