Bandwidth management x QoS

RouterOS General
1

Hi all!

My AP is routed and it’s the gateway of all customers that is registrated on the Wifi card. It works as DHCP server too and it makes the bandwidth control using individual Simple Queues created dynamically using the return of the freeradius on the moment of the DHCP request.

Now I want to implement a QoS system and I’ve a doubt in where is the best place to put it.

If I put the QoS on the RouterOS that is on my connection with the Internet the QoS will help in something??? Or do I need to make the QoS on each AP of my network, because that the bandwidth management is made on the APs?

Another doubt is about the behavior of the Queue Trees and Simple Queues. I’m thinking in make the QoS using the follow technique:

  1. I’ll have some Firewall Mangle rules to mark the packets;
  2. I’ll have some QueueTrees that will be used to give priority the traffic using the marks of Firewall Mangle
  3. After the traffic pass on the QueueTree it goes to the Simple Queues, where I’ve individual bandwidth limitation of each customer.

Am I right about of the implemantation of the QoS on my network?

Best regards!

Limit downloads at GW or AP and customer uploads at CPE if you want to save on wireless bandwidth.

Thanks Michael!

It’s good and I’ll do the bandwidth control (download/upload) in all my customers equipments.

But now I’m with doubt about the QoS. I don’t know if I’m going to have best results putting the QoS rules (mange/queue tree) on the AP (that is the gw of the customers) or putting the QoS rules on the main gateway (the machine that is connected with the internet). The doubt is because the bandwidth management is made on the AP.

Best regards!

Somebody can help me with this doubts?

Thanks

Your question is not very clear. Try explaining in more detail.

Hi Michael, thanks for you reply.

I’ll try to explain better… let’s go:

My AP is working as router. All the customers has individual simple queues to limit the bandwidth.

Now I want to implement a efficient QoS using Queue Trees. My doubt is:

  • How is the traffic flow between the Queue Trees and the Simple Queues? Does the traffic go first through the Simple Queues or through the Queue Trees?

  • Does the QoS implemantation must be before or after the bandwidth control?

  • How is the best for to do the QoS implementation? Put the QoS on each AP of my network (all the APs are working as routers) or put one central Mikrotik to do the QoS implementation?

I hope I’ve been more clear now!

Best regards

It depends. Simple queues can limit traffic in one or more of global-in, global-out or global-total. See http://wiki.mikrotik.com/wiki/Queue#Simple_Queues for details.

Does the QoS implemantation must be before or after the bandwidth control?

Personally, I prefer to go speed limits THEN priority configurations (queue trees).

How is the best for to do the QoS implementation? Put the QoS on each AP of my network (all the APs are working as routers) or put one central Mikrotik to do the QoS implementation?

This depends on several factors, too. For the most part, if the Internet feed is the bottleneck (as it is with most WISPs), then putting a good QOS system at the border is sufficient. Send me direct email butche@butchevans.com if you are needing a QOS solution pre-built.
