[Cerowrt-devel] Routing limit question

[Cerowrt-devel] Routing limit question

[Ernesto Elias]

[-- Attachment #1: Type: text/plain, Size: 445 bytes --]

Hello everyone!
I have a question about the wndr3800 routing limit. I went back to the
older submissions to see if I can find what would be the answer for it. But
in my search I haven't managed to find a definite answer. From what I seen
about setting the limit it can do with SQM is 50, 60, or 80 mbit. I'm just
wondering if anyone can shed some light for me here as I have verizon fios
and my speeds are 50 dl/50 ul. Thank you guys very much!

On at least one verizon device I've tried it appeared that they had
SFQ or something similar on egress from the modem.

http://www.bufferbloat.net/projects/codel/wiki/RRUL_Rogues_Gallery#Verizon-FIOS-Testing-at-25Mbit-up-and-25Mbit-down

So you only needed to shape the download. which is good as we start
peaking out at 50Mbit download total. But only measurements can tell.

Oh OK I mean I was just wondering because I was trying to figure out what
should I have put in the sqm tab because I saw that the wndr3800 tops out
at 50 mbit combined of download and upload right? As of now I have it at
25/25 on the page. Is that right or should I just shape the upload?

shape the download only, then measure. shape the upload only, then measure.

	So on Hnymans community openwrt build a few fortunate ones on excellent lines seem to get decent results even at 110-120 Mbps combined:
https://forum.openwrt.org/viewtopic.php?pid=250989#p250989
and:
https://forum.openwrt.org/viewtopic.php?pid=251013#p251013
I have no idea why and both lines were reasonably well-behaved even without any AQM/QOS...

Also I wonder whether when we increase the quantum for higher rates to give HTB some breathing room, whether we also should increase burst and cburst? My hunch is that quantum affects the switching between the leaves, while busts and cburst should allow to dump more data to lower layers inside each leaf qdisc. And since we are running behind, maybe taking a bigger shovel can help some. (I assume this needs to be titrated not to kill latency under load, but if we can only effective have HTB execute x times per second we can easily afford to dump line-rate/maxHTB_iteratin_rate bytes per opportunity, no?) My own internet link is way to slow to test this...

Best Regards
	Sebastian

The first result i gotten by only shaping the uplink and the second results
are for only shaping the downlink...

and for the testing i put 0 on the for the downlink and uplink when I was
testing for the opposite. and I put 50000 in it when I was shaping it for
the test. Am I doing it right ?

It looks to me as if the actiontec has pretty good qos all by itself.

Sorry there are two conversational threads here on hynyman s thread they
are benchmarking vs an anctiontec.

Also it does seem like fiddling with the burst parameter to htb seems
warrented.

Re: [Cerowrt-devel] Routing limit question

[Sebastian Moeller]

Hi Ernesto,

I would recommend to not run the netperf processes on the router you want to assess, if possible. Shaping at the rates you are interested in probably will take 100% CPU of the router, so there is no slack for running net server and netperf instances at the same time. Also I would recommend to use netperf-wrapper (https://github.com/tohojo/netperf-wrapper) instead of netperfrunner.sh as it allows so much nicer visualization of the queueing over time. netperfrunner.sh is great tool for quick testing and figuring out link capacities and worst case latency under load increase (LULI), but for more thorough comparisons it ain’t made. Netperf-wrapper will run under linux and macosx natively, but will also run (well enough) in a linux virtual machine on a windows box.


Best Regards
	Sebastian

Re: [Cerowrt-devel] Routing limit question

[Sebastian Moeller]

Hi Dave,

so I just went with what I have available, shaping between linux host on se00 and macbook on sw10, shaper on se00 (25M/25M that is the maximum wireless throughput with the current router position): burst/cburst set at 1600(default) 16000 and 16000. And lo and behold the sirq gets smaller the larger burst/cburst is set. Now tho test is just too confounded by my bad wireless to be proof, but it certainly justifies the time to expose knobs in the GUI to set burst/cburst/quantum values for HTB for each shaper instance independent for ingress and egress… (I do not assume that this will even double the throughput of a wndr as a router, but even just 10-20% will make a difference ;) (I will eat my own dogwood, since I am about to upgrade from 16M/2.5M to 50M/10M right into where our sirq pain starts)).



Best Regards
	Sebastian

My hunch is that quantum affects the switching between the leaves, while busts and cburst should allow to dump more data to lower layers inside each leaf qdisc. And since we are running behind, maybe taking a bigger shovel can help some. (I assume this needs to be titrated not to kill latency under load, but if we can only effective have HTB execute x times per second we can easily afford to dump line-rate/maxHTB_iteratin_rate bytes per opportunity, no?) My own internet link is way to slow to test this...

Well Sebastian sir, I am taking your advice and I'm on windows 7 so right
now I'm downloading virtualbox and xubuntu. I don't know if there is one
that you guys recommend. Well... I am new to all this stuff so I'm asking
you to please help me on the subject like after everything is up and
running on the computer, what other steps do I do afterwards and forgive me
like I said I'm new ot all this stuff because I want to be able to find my
link capacity when using SQM. and Thanks for the help!

	I only tested ubuntu 12.04LTS, but certainly I would try the current 14.07 LTS today.

	Oh, sure I am happy to help you with getting better data ;)

> what other steps do I do afterwards and forgive me like I said I'm new ot all this stuff because I want to be able to find my link capacity when using SQM. and Thanks for the help!

	First step is getting the vitalized linux up and running, then python 2.7 (I assume that python will be part of the distribution), with matplotlib; and finally netperf-wrapper. I assume it might take a bit trying to figure out all the required packets installed, but it should be reasonably quick to get this up and running… Just give it a try and let me know if/where you get stuck
	It would be most excellent if you could document the whole procedure somehow so we could put it somewhere on the net to make it easier in the future...

I don't necessarily think knobs need to be exposed. Perhaps tuning the
burst parameter as a function of the
induced latency would be about right. At 10mbits, a single 1500 byte
packet takes 1.3ms to egress. So if we
were to aim for .5-2ms worth of burst across the operational range of
the shaper, that might work. In the
case of cable, a grant request takes 2-6ms, anyway.

So at 80mbit, a burst size of 8-16k seems possibly optimal. It could
be higher (other overheads in the kernel).

Now that we have a knob to jiggle, I'll go jiggle it when I have some time...

I note that I'm under the impression cburst can be twiddled with also
to make "powerboost"'s behavior better,

Re: [Cerowrt-devel] Routing limit question

[Dave Taht]

OK, I tried a few combinations of burst and cburst on a cerowrt box,
using 90/10 as a up/download speed.

burst 64000 cburst 64000 was a bit of a win, in most respects, but odd
in others.

Alright Sebastian, I've managed to get the virtual box and Ubuntu running
on the computer and I went to go see the packages I have no idea which one
to install there's a whole lot of them. Forgive me this is all new to me.
Which one do I acquire and how to install it?

Interesting....  can this be specified on the advanced options string
(ingress only)?

	Unfortunately not, the advanced option string is just passed to the leaf qdiscs, but if you are willing to edit simple.qos you can change:
LQ="quantum `get_mtu $IFACE $CEIL`”

into:
LQ="quantum `get_mtu $IFACE $CEIL` burst 64000 cburst 64000” for either ingress or egress or both to get the desired effect. As always “tc class show dev ge00” and "tc class show dev ifb4ge00” should show you wether your changes took hold (assuming you use a recent sqm-scripts and ge00…).
	So I probably will try to expose these options in an additional optional hidden-by-default entry fields in a future revision.

	Great, so I see an increase in ingress rate for cburst 64000 with no real side effects, but burst 64000 cburst 64000 somehow manages to punish one of the BE streams. Luckily the latency under load increase stays really small. Do you know whether sirq differed between the tests? (I assume no it should be pegged to 90-100% during all tests as the effective good put increased…)

Best Regards
        Sebastian

My hunch is that quantum affects the switching between the leaves, while busts and cburst should allow to dump more data to lower layers inside each leaf qdisc. And since we are running behind, maybe taking a bigger shovel can help some. (I assume this needs to be titrated not to kill latency under load, but if we can only effective have HTB execute x times per second we can easily afford to dump line-rate/maxHTB_iteratin_rate bytes per opportunity, no?)

Re: [Cerowrt-devel] Routing limit question

[Sebastian Moeller]

Hi Ernesto,

so I would recommend to first install git from a terminal in your ubuntu virtual machine:
	sudo apt-get install git

then create a directory where to store horse netperf-wrapper:
	mkdir -p ~/bufferbloat ; cd ~/bufferbloat

then clone the netperf-wrapper repository:
	git clone git@https://github.com/tohojo/netperf-wrapper

now you can test what is missing by calling:
	./netperf-wrapper
this will most likely complain about missing components, please send the output of this command so we can take it from there.

In the unexpected case that the above command just success please try:
	date ; ping -c 10 netperf-eu.bufferbloat.net ; ./netperf-wrapper --ipv4 -l 300 -H netperf-eu.bufferbloat.net rrul -p all_scaled --disable-log -t netperf-wrapper_test 

and again send the output…

And finally if all the above succeeds please try 
	./netperf-wrapper —gui

and send the output

Hope that helps...

Best Regards
	Sebastian

Shaping at the rates you are interested in probably will take 100% CPU of the router, so there is no slack for running net server and netperf instances at the same time. Also I would recommend to use netperf-wrapper (https://github.com/tohojo/netperf-wrapper) instead of netperfrunner.sh as it allows so much nicer visualization of the queueing over time. netperfrunner.sh is great tool for quick testing and figuring out link capacities and worst case latency under load increase (LULI), but for more thorough comparisons it ain’t made. Netperf-wrapper will run under linux and macosx natively, but will also run (well enough) in a linux virtual machine on a windows box.

Hello Sebastian, well I followed your directions and when I inputted the
command git clone git at https://github.com/tohojo/netperf-wrapper

It said too many arguments...
What do I do now?

Hi Ernesto,

	Oops, sorry, it looks I copy and pasted the wrong line from my .bash_history… the following should work:

git clone https://github.com/tohojo/netperf-wrapper

also note Dave’s mail where he recommends:
sudo apt-get install fping python-qt4 python-matplotlib

to get more of the requirements for netperf-wrapper installed,  please run this after coning the netperf-wrapper repository.

Thanks a lot…

	Sebastian

Re: [Cerowrt-devel] Routing limit question

[Sebastian Moeller]

Hi Ernesto,

it seems that I forgot to mention that you need to change into the buffer bloat/netperf-wrapper directory first:

so please try:
cd ~/bufferbloat/netperf-wrapper
followed by:
date ; ping -c 10 netperf-eu.bufferbloat.net ; ./netperf-wrapper --ipv4 -L 300 -H netperf-eu.bufferbloat.net rrul -p all_scaled --disable-Log -t netperf-wrapper_test

that hopefully should start netperf-wraper for good and display an image showing downlink bandwidth, uplink bandwidth and latency over time. Please note that this plot shows the average rates of 4 streams (for up and down), so for your total bandwidth you need to multiply the numbers by 4. 
	Akso note that with “netperf-wrapper —gui” you can select different plot types that can show total bandwidth or box whisker plots (just play with the GUI).


Best Regards
	Sebastian

I assume it might take a bit trying to figure out all the required packets installed, but it should be reasonably quick to get this up and running… Just give it a try and let me know if/where you get stuck

Shaping at the rates you are interested in probably will take 100% CPU of the router, so there is no slack for running net server and netperf instances at the same time. Also I would recommend to use netperf-wrapper (https://github.com/tohojo/netperf-wrapper) instead of netperfrunner.sh as it allows so much nicer visualization of the queueing over time. netperfrunner.sh is great tool for quick testing and figuring out link capacities and worst case latency under load increase (LULI), but for more thorough comparisons it ain’t made. Netperf-wrapper will run under linux and macosx natively, but will also run (well enough) in a linux virtual machine on a windows box.
