Re: [LARTC] nesting htbs
I wouldn't put sfq on interactive - I would add a bfifo so I could set and play with the buffer lengths. I agree. I think SFQ might reorder packets? It sometimes seems to cause some difficult to trace gremlins on my VoIP stuff, which might be due to packet re-ordering? Best to stick with a bfifo I think Ed W ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Yes as long as you are shaping downloads by shaping egress on the lan facing interface. Andy. ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

As you already use them for some things you may want to use --or-mark and u32 to match them eg. iptables -A POSTROUTING -t mangle -p icmp -j MARK --set-mark 0x0100 and so on for traffic types using high byte then use low byte and --or-mark for addresses iptables -A POSTROUTING -t mangle -s 192.168.0.1 -j MARK --or-mark 0x0001 Then filter top level with a mask like tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match mark 0x0100 0xff00 flowid 1:20 and leaf levels tc filter add dev eth0 parent 1:20 protocol ip prio 1 u32 match mark 0x0001 0x00ff flowid 1:200 That assumes you really need iptables for marking traffic type - if you could use tc filters for that, then just use iptables for the addresses. Something I've only just noticed from a comment in the code - htb can use mark without the need for lots of filters. You only need one empty filter on the root (maybe you can still nest) like - tc filter add dev eth0 parent 1:0 protocol ip prio 1 fw and then if you arrange for your classes to be the same minor numbers as the marks it will behave like using classify. You need to set the major number of your htb (1 in example above) in the top 16 bits of the mark. There is also a netfilter pom-ng patch IPMARK that will set marks based on ipaddress.

Hello all,
I am running a coop satellite link for my aviation company here in
Iraq. (silly blog www.stardotstar.org). I am running tc with htb
with good success so far. I am working on improving it though and
need some help. Currently I have just 4 classes, syn/ack/ping,
webchat, http, and then other. We are really happy with how this has
improved our ability to call home from our rooms and do video chat.
However, I would like to do a better job of making sure that each
IP is getting a fair share because it seems like sometimes one video
or audio chat bullies another one into slowing down and one guy is
having a great video and audio feed while someone elses audio only is
suffering. I've seen some references to wrr and also to making a
class for each IP. There doesn't seem to be much current documention
on wrr, so I'm trying to set up nested htbs. Here are my questions:
1. Which makes more sense, to nest my 4 classes of traffic inside of a
class for each IP, or to make a class for each IP in each of my 4
classes. I'm leaning towards the latter so that someones web traffic
can't borrow from the interactive traffic classes.
I would do the latter also. I would have just one interactive class and
give it a rate that is say 3/4 of the ceil, the bulk classes can still
borrow the unused.
2. I've done a test, and can't get any traffic into the nested
classes. Here is my code:
#1:20 LOW DELAY--CHAT DATA
#includes the minimize delay FW TOS
tc class add dev ${UPDEV} parent 1:1 classid 1:20 htb rate 200kbit
ceil ${UPCEIL}kbit burst 6k prio 1
tc filter add dev ${UPDEV} protocol ip parent 1: pref 20 u32\
match ip tos 0x10 0xff flowid 1:20
tc filter add dev ${UPDEV} protocol ip parent 1: pref 21 handle 5 fw
classid 1:20
tc filter add dev ${UPDEV} protocol ip parent 1: pref 21 handle 6 fw
classid 1:20
so marking is thing that i need for limiting NATed uploads to internet ?
when limiting downloads i do not need marking ?
am i right ?
