Does that run RouterOS 7.2?<br>
<br>
I am not in a position to "recommend" anything, but I am very<br>
interested in the current bufferbloat'd behaviors of<br>
VDSL2 and FTTH on what you currently have deployed, and what you plan to deploy.<br>
<br>
At a gigE, I am getting back behaviors worldwide that range from<br>
seriously underbuffered (5ms), to unable to transmit Gbit<br>
simultaneously in each direction without the router running out of CPU<br>
(very common), to 30-90ms. On various shapers, at 200Mbit, I'm seeing<br>
20ms-200ms. and the lower values can really hurt single flow<br>
throughput.<br>
<br>
So I've been trying to get folk do tests worldwide with the rtt_fair<br>
test in flent.org There's a server in sydney. Here's an example of the<br>
otherwise rather nice turris falling apart at 200Mbit symmetric:<br>

<br>
If you go the mikrotik way, I'm happy to say they finally made "cake"<br>
work pretty good in the 7.2 release, which,<br>
so long as you don't run it out of cpu, essentially is doing zero<br>
latency for most packets while having enough buffering to sustain<br>
cubic at 260ms rtt. A very long thread with a ton of explanations and<br>
pictures here:<br>

<br>
There are a ton of other branch office quality gear that run "my"<br>
stuff now, also, ubnt, riverbed, etc, etc. I figure y'all have way<br>
more technical requirements that just killing off bufferbloat,<br>
however!<br>
