hi all,
have anyone tried changing the tcp setting in the source files ? for eg
decreasing the TCP_KEEPALIVE_TIME from 2 hours to say 10 min --
(120*60*HZ) to (10*60*HZ) in include/net/tcp.h ??
changing the parameters in static unsigned long tcp_timeouts[] in
I trying to modify the files as it is writen into the
htb pach (htb2_2.4.17.diff)

make dep
make clean
make bzImage
i find an error message:

In a long term always droping from the largest subqueue
gives you equal subqueues.
And, of course, one could have it drop them using a RED-like algorithm
to make the sessions stabilize themselves better.
what they have) is better. May be doing it like the cbq with average
packet size
Isn't it possible to arrange this with cbq and sfq leafs?
Yes ... By building a big CBQ/HTB tree with one leaf for each IP ... :)
I'm not sure how efficient / inefficient that is.

Hello!
everyone,
For performing traffic shaping using HTB, is there a parameter to define
the queue or buffer length where packets get queued (once the allocated
bandwidth is being used up), instead of just getting dropped (policed).For
example, in TBF there is a parameter

Do you have any information about?
Is there a tool does it on Linux?
Thanks for the answer,

Hi,
I'm running an experiment and I'm having some problems in my Core Router.
I'm using MGEN to generate the traffic. For some reason the core router
is not detecting the packets as I check the count of packet being sent using
tc -s qdisc. While in the other hand when I generate the traffic
Wow. It is very interesting. Did you tried to read counters
in iptables -vL and compare counts ? Like to read value from
/proc/net/dev compare to count of packets at INPUT chain and
then compare with no of packets in DROP chains.
It could give us better picture where are the packets going to.
What is the problem ? use cat ethloop_script|./ethloop
for example ..

Does anyone know how to use ethloop?

No, i do not think like this. If we think just for TCP connections
we may end up with ideas like changig window size. TCP tunes to send this
way but it also tries to send more each 5 seconds, if it have data.
please not this. :-) Packetizer sw goes this way and it is

For the sake of a play-by-play (and why it wouldn't quite work right
initially):
1) we need to dequeue a packet
2) we ask the 11 bit lower SFC for a packet.
3) it asks the upper SFC
4) the upper SFC takes the next bucket, based on IP, and gives us a
packet.
5) the lower SFC takes that packet and

Is it the expected result?
I gussess the all 60kbps (excess) should go to prio 0 or by proportional
to rate in each class.
