Equal bandwidth for all users - Per Connection Queue (PCQ) on Linux?

[Valent]

Hi,
Mikrotik has nice qos technique called PCQ [1] that easily splits bandwidth equally to all connected clients.
PCQ dynamically spreads bandwidth between users. For example if there is 10MBits/s and only two clients both can be set to get 5Mbits, and if there are 10 clients, each gets 1Mbit.

Is this possible with linux tools?

Have a read about qdiscs, start with man tc. There are some good references and howtos with a Google search on these topics too.

I've never heard of MicroTik but it appears to just be Linux which runs on a specialised x86 chassis with a heap of network ports that ends up looking like a regular switch.

I expect MicroTik is using the regular Linux classful qdiscs to do what you describe. Maybe have a look around in their RouterOS download?

There's a company called Arista who make similar products, their network gear is actually based on Fedora.

I know linux queuing techniques, and these don't offer the abbility of PCQ, please read about Mikrotik's PCQ, it is not as simple a question as it seams.

PCQ dynamically spreads bandwidth. If there is 10MBits/s and only two clients both automatically get 1/2 (5Mbits), and is there are 10 clients, each gets 1/10 (1Mbit).

I haven't yet seen any qos technique on linux that allows this, but my quess is that some linux networking guru has this figured out.

I suspect you may be right, but that person might not post on an unofficial support forum for a desktop distro

You'd probably have more luck on linux-netdev list.

Didn't know about that list, thank you.

I read LARTC but there is no mention of queuing technique similar or eaqual to PCQ, please read my post with a bit more attention.
