cbq init query
Hello,
Just wondering, from what I have been reading, would using
the word bounded solve my problem? I have not actually tried
using bounded yet, I will asap, however from what I
understand it only applies to classes? I simply have 2 cbq
files, cbq-1200.internal, and cbq-1200.external, both of
which are identical except one says eth1 instead of eth0.
Within each file I have :

[LLVMdev] LLVM optmization
The following C test program was compiled using LLVM with -O3 option and MSVC with /O2.
The MSVC one is about 600 times faster than the one compiled with the LLVM.
We can see that the for loop in MSVC assembler is solved in the optimization pass more efficiently than that in LLVM.
Is there an way to get a optimization result in LLVM like that of the MSVC?

shaping fails when using p2p apps?
Hi there,
We''re running a small ISP and all the users are shaped to 384/512/768k
both ways (whichever package they choose).
The router is a linux (debian sarge), the kernel is 2.4.25 right now.
All users are getting 10.1.1.* ip addresses (eth1) and eth0 connects
to the isp using ethernet (via a media converter, it''s fiber from
there). They''re nat''s using

[LLVMdev] LLVMdev Digest, Vol 55, Issue 16
1. Re: LLVM optmization (Bill Wendling)
Hi,
The IR is not wrong. I said that the assembler generated by MSVC is quicker. We can see that the for loop, in the TESTE function, is done without jump's in the MSVC and with jumps in LLVM. I think thats the point.
If we don't use threads, the result is the same. My test were done with one billion interactions in the for loop. The MSVC

QoS on a bridge+NAT
I have a setup where I have three NIC in a Debian box. I have eth1
conected to internet and eth0 NAT''ed to 192.168.1.1. eth1 and eth2 are
bridged together, given ip 192.168.122.2.
What I want to achieve is to perform traffic shaping on the bridge as
well as prioritizing the traffic from eth0 very low. (This is from
trental flat ...) However it seems that I am unable to perform thhe

HTB: Problem with excess bandwidth distribution
Hello,
I have a serious problem with HTB which I wasn''t able to solve myself.
I run a masquerading router with ppp0 as interface to the Internet.
Three clients need to share a downstream of 1 MBit, which I want
to divide with tc.
When I see a packet being forwarded to one of these clients, I give
it the appropriate unique mark:
iptables -t mangle -A FORWARD -d 192.168.34.141 -j MARK

Besides being classful, CBQ is also a shaper and it is in that aspect
that it really doesn''t work very well. It should work like this.

Incoming trafic shaping (depending on src IP)
Hi there,
i''m trying to shape incoming trafic on my linux box.
I want it to depend on the source IP adress of the packets (in fact, i got
a VPN on an ADSL link and wanted to get at least/max 64Kbit/s for the VPN)
So i tried this :
tc qdisc add dev ppp0 root handle 1:0 cbq bandwidth 512Kbit avpkt 1000 cell 8
tc class add dev ppp0 parent 1:0 classid 1:1 cbq bandwidth 512Kbit rate

RE: CBQ-wondershaper superior over HTB-wondershaper?
Hello Thilo,
What did you find superior with CBQ-wondershaper over HTB-wondershaper? We have not been using wondershaper specifically but our simple tests so far seem to show that htb is much easier to configure for a given target shape (i.,e accurate) compared to CBQ.

Low-priority traffic
Hello,
I''m a total tc newbie, and I''m trying to tweak the wondershaper script
(http://lartc.org/wondershaper/) to get a slightly different result.
Excuse me if I will not use the correct technical terms, it''s a whole
new world to me :)
wondershaper.htb creates 3 HTB classes; 1:10 is high prio, 1:20 is bulk
(default), and 1:30 is low priority. The classes are

how to emulate large IP routing table
Hi all
I am conducting the experiments comparing IP router forwarding delay and
MPLS LSR forwarding delay, it is obvious in theory MPLS in Core should be
faster than IP, but for small netork (only have several core routers),
result show it is not, this is why I want emulate a large IP routing table
in one core router.
can I do it and how ? right now I use static routing table (by using command
