the key in AP (NV2) performance is always that

- the lowest signal client/data rate is in control of the total throughput.

so when a cpe maxes out on the connected datarate, it takes down the overall throughput of the AP


the way to avoid this is, is to hard set the queue on the client to lets say 80% of the possible wireless data rate and so protect the AP from dropping throughput.

what is the way to go here, write an script for cpe, or implement this in NV2 protocol on the station/cpe side.

First can we really compare Cisco Meraki to Mikrotik NV2!

/queue simple
add max-limit=10M/10M name=queue1 target=wlan1

nice lets try remove all queue and try set only hardware queue

Code: Select all

/queue interface
set wlan1 queue=only-hardware-queue 

let me know the results.
many thanks

Thnx ADahi , think you make magic happen here.

after some testing i found using ccq is a better approach

Code: Select all

{
:local CX [/interface wireless registration-table get 0 rx-ccq ];
/queue simple set 0 max-limit=((($CX * 5) / 10)."M");
}

one can play with the factor "5" , ideal would be that its dynamic to the ccq.

so if ccq is 20%, , the divide number would be 1 for example, and if ccq is 100% divide would be 9.


i see big improvements in test setup.

such a simple solution that makes big difference by preventing a client with low ccq degrading AP overall throughput.

now the script need to be fine tuned and run with scheduler or should it be looped script and only change queue if needed ?

also it needs to set up and down limits according to ccq up/down rates.

but it is big improvement for sure to AP throughput.

@Mikrotik programmers. is it not possible to integrate this approach in NV2 ?

i played with that a lot.

when doing so its very hard to predict the behavior ,

bottom line is that the connection how is maxing out , is the bottleneck for all others.

when using the script as it is at this point makes it already prevent clients maxing out there connection for whatever reason.

It is encouraging to read you state this approach makes a big difference, however
(1) As ROS is mostly software based any extra function(s) which require constant CPU cycles which will result in a drop in performance with misleading results?
(2) NV2 only calculates CCQ when traffic is flowing, so will you have a cut off (CCQ less than 20% - do not run script!)

{ 
:local CX [/interface wireless registration-table get [/interface wireless registration-table find interface="wlan1"] rx-ccq ];
:log info [$CX];
/queue simple set 0 max-limit=((($CX * 8) / 13)."M"); 
}

sorry to hijack the topic thread but I am looking for a script to detect when 1Mbps data rates are being used by a CPE and print to a file?

You will discover there is “Guru’s” (helpful users) in different sections like - Wireless networking, Scripting, forwarding protocols, ...etc.
And you will usually get good practical advice from them in those sections,
For me my main area of interest and forum activity has been Wireless Networking as a WISP user, my business has had me jumping from one technical area to another but maybe my New Year Resolution should be learning scripting in depth?

ok, how can I help
explain your plan

did you use this before?
