Wondershaper QoS discussion

[Styno]

In an efford to try to keep the firmware topics clean, this thread will discuss all questions and remarks regarding Wondershaper' QoS (or Bandwidth control).

Some must-read info:
Wondershaper info

Oleg' FAQ for v1.7.5.9 firmwares

WIKI (dynamic information system)

[Oleg]

Styno, please remove bootCmd stuff, it's not correct.

Styno, please remove bootCmd stuff, it's not correct.

ghehe hit the EditText button then

[Oleg]

ghehe hit the EditText button then

Too simple.

[Styno]

Hmm, i didn't add the bootCmd section at all , someone else did. It's a WIKI...

[Styno]

Okay ontopic now:
I configured the router with post-boot scripts to enable wondershaper and did a test:
On the router I did: 'ping www.tweakers.net -t' and the pings returned in approximately 15 ms.
Then I started a download and the pings went up to approximately 500 ms instantly.

I reviewed the wshaper script and it explicitly provides priority to ICMP (ping e.g.) over other traffic. Why is my ping going sky high then? Queueing on the ISP side?

@styno or other people who running ws
can you (or the others) adapt the wiki for the new firmware 1.8.1.7-1, i think there are only changes in file stuctur right?
for a newbie in ws(that i'm), it would be a big help if there is the new structur in.

@all
i've read the whole qos thread and the wiki, but i didn't understand the structur of the script parameters. the only thing i wanted to do is:
to set up my voip ip adapter (IP adresse: 192.168.1.4 in DMZ) to the high priority mode (most important the upload speed).
the other traffic (up and download) should get lower priority.
my connection is adsl (with 786down/128up). firmware on wl500g is 1.8.1.7-1 .

my file post-firewall:

#!/bin/sh
/sbin/wshaper start "$1" 700 100

i know that the setting above is not correct for the setting i wish. but i don't understand the parameters. and if i enter "wshaper status eth1" nothing happend.

if someone could help me, it would be nice
thx a lot.

ps: sry for my english ;-)

--edit--
if i enter

wshaper start "$1" 700 100

the following appears:

Cannot find device "root"
Error: Qdisc "1:" is classless.
Error: Qdisc "1:1" is classless.
Error: Qdisc "1:1" is classless.
Error: Qdisc "1:1" is classless.

Unknown qdisc "ffff:", hence option "ingress" is unparsable

did i something wrong?

pls help! ;-)

wshaper start "$1" 700 100

did i something wrong?

pls help! ;-)

To run interactively, you will need to replace $1 with your WAN interface name (eth1 for static/dhcp, ppp0 for pppoe/pptp).
$1 should be used inside post-firewall only.

thx oleg,

do you also know a fast way how i can set up my voip device(192.168.1.4) to the highest priority? and reserve (if its in use) a upload and download speed of 100kb for it.

i'm not a completly idiot, but it is so difficult to understand.

You can put your voice traffic in the low delay queue by adding the following lines in the wshaper script
tc filter add dev $DEV parent 1:0 protocol ip prio 10 u32 \
match ip src 192.168.1.4 flowid 1:10

Best, you can consider creating a new voice class with high priority and put voice traffic into it. You wshaper script will be something like :

# voice class
tc class add dev $DEV parent 1:1 classid 1:100 htb rate 100kbit \
   burst 6k prio 1
 
# low delay class
tc class add dev $DEV parent 1:1 classid 1:10 htb rate ${UPLINK}kbit \
   burst 6k prio 2

# bulk & default class 1:20 - gets slightly less traffic,
# and a lower priority:
tc class add dev $DEV parent 1:1 classid 1:20 htb rate $((9*$UPLINK/10))kbit \
   burst 6k prio 3

tc class add dev $DEV parent 1:1 classid 1:30 htb rate $((8*$UPLINK/10))kbit \
   burst 6k prio 3     

# put voice traffic into high priority class
tc filter add dev $DEV parent 1:0 protocol ip prio 10 u32 \
       match ip src 192.168.1.4 flowid 1:100

thx a lot i will test it tomorrow.
good night to all

Hi all,

thanks to this huge thread i mnaged to modify the wshaper script in order to prioritize VoIP trafic, but i'm confused by some things.

First of all here is my setup :
1 Bewan ADSL2+ Modem on a 512/128 DSL connection
1 Wl500g, connecting to the internet with PPPoE
2 computers, both are connected through wireless. One of them is running P2P software (eMule)
1 Linksys ATA adapter connected through cable to the WL500

I'm note sur which interface i should set up for bandwidth management. I tried to use eth1, but it seems that this not sort of a solution since wshaper is shaping the connection underlying the PPPoE connection i.e. the data being shaped is the data moving through the modem and the router....
So i made some tests using ppp0 and br0, trafic shaping seems to occur but when i make a VoIP call communication is not of a good quality.
I can see that P2P trafic is being slowed down, but not enough and not fast enough i.e.: the longer the voIP call is, the better the quality will be. I have to wait about 2 minutes tio get acceptable quality.
What should i do to have all other trafic drop immediatly when i make a VoIP call ?

here is what i added to the script

# VOIP SIP
tc filter add dev $DEV parent 1:0 protocol ip prio 10 u32 \
      match ip tos 0x68 0xff \
      flowid 1:10

# VOIP RTSP
tc filter add dev $DEV parent 1:0 protocol ip prio 10 u32 \
      match ip tos 0xb8 0xff \
      flowid 1:10

i also commented all the upload stuff at the end of the script...

Any advices ?

thank you...

Thanks to this thread and the script written by Akbor (wow) I have now implemented WonderShaper in the WL-500g to take care of my VOIP. The quality of the conversations is now good also when surfing, down- or uploading or looking at my webcam from outside the LAN.

Although I was a real newbie without a single experience in Linux, I was able to implement this script in the WL500g with some extra efforts. To help others I have put a simple How-To for newbies on the wiki-page:

http://wiki.wl500g.info/index.php/PackageWondershaper

Please have a look to see if I forgot something or correct errors.

Thank you all!

Finally I was able to make it work for VOIP! The problem was that the copy-paste did not work for me well, I had many empty spaces in the code...

here is the log:

I would be interested to know if these lines are correct for the Bitlord to place it under bulk priority?

tc filter add dev $DEV parent 1: protocol ip prio 10 u32
match ip sport 65534 0xffff
flowid 1:30

Can anyone post his working config again?

Thanks.
