Per Connection Queue (PCQ) is a queuing discipline that can be used to dynamically equalize or shape traffic for multiple users, using little administration.

Equal Bandwidth for a Number of Users

Use PCQ type queue when you need to equalize the bandwidth [and set max limit] for a number of users. We will set the 64kbps download and 32kbps upload limits.

There are two ways how to make this: using mangle and queue trees, or, using simple queues.

1. Mark all packets with packet-mark all:

/ip firewall mangle add chain=prerouting action=mark-packet new-packet-mark=all passthrough=no


2. Setup two PCQ queue types - one for download and one for upload. dst-address is classifier for user's download traffic, src-address for upload traffic:

/queue type add name="PCQ_download" kind=pcq pcq-rate=64000 pcq-classifier=dst-address
/queue type add name="PCQ_upload" kind=pcq pcq-rate=32000 pcq-classifier=src-address


3. Finally, two queue rules are required, one for download and one for upload:

/queue tree add parent=global-in queue=PCQ_download packet-mark=all
/queue tree add parent=global-out queue=PCQ_upload packet-mark=all

If you don't like using mangle and queue trees, you can skip step 1, do step 2, and step 3 would be to create one simple queue as shown here:

/queue simple add queue=PCQ_upload/PCQ_download target-addresses=192.168.0.0/24

That's it!!!
