is there a test result for this function?
What’s new in 6.40rc6 (2017-May-11 12:53):
*) wireless - added option to change “nv2-downlink-ratio” for nv2 protocol (CLI only);
*) wireless - added option to set “fixed-downlink” mode for nv2 protocol (CLI only);
Milestone for Mikrotik. One p2p link 80/20 works nice. Soon test p2m.
What’s throughput difference for dynamic and 80/20 ratio?
It works as expected in our test setup, download and upload throughput are just restricted to desired ratio.
If the throughput with dynamic ratio is 100mbps half duplex then with 80/20 ratio
download will be limited to max ~80mbps and upload to max ~20mbps.
We have one test p2p link (reasonably clean 40MHz channel, signal level-58dBm) and it works fine with latest RC after some minor tuning.

What is the difference before and after. Can u give the test results in both bandwidth test? thanks
Actually, the only news here is ability to control download/upload throughput ratio - and that, as I said, works (mostly) as expected.
For p2p you could get more with old dynamic ratio because with new fixed ratio there is max 80% “per side throughput” limit.
In my example, with dynamic ratio we could get 100mbps on bandwidth test (half-duplex) and with fixed ratio we’re getting up to 80mbps because of that 80% ratio limit.
So, there is no real throughput improvements with this new option (at least not in p2p) but it gives us ability to apply more control in some specific scenarios.
What would really make a difference in p2mp scenario is manual control over client’s priority or air-time (percentage of AP’s time designated for each CPE connected to AP). NV2 is already doing this automatically better than nstreme but still… manual control over that per CPE would be a GIANT leap forward.
In that way, one bad CPE wouldn’t be able to ruin AP performance for the rest of the clients.

Sadly, nstreme still getting better at ptmp než nv2 (20Mhz, 2x2). Nv2 ends at 40-45 Mbit but nstreme 45-60Mbit or more.
