<html><div style='background-color:'><P>now i'm read a lot of knowledge paper about \
traffic control in linux because now i'm try to develop and research about traffic \
shaper so can everybody tell me about my topic </P> <P>... Is it can do for \
real????</P> <P>my topic is "<BR>now, many organization use traffic shaper for \
control traffic and bandwidth because don't want something example <BR>some mac \
address, ip address, traffic in that port or that application use a lot of bandwidth \
more than it appropriate should use example if people in organization try to \
use </P> <P>p2p application ,it may make a lot of problem for all bandwidth in \
organization</P> <P>now most famous algorithm to manage queue in mastershaper is \
"HTB" but i have just read some paper their tell about<BR>"HFSC" algorithm ,it's very \
good to manage real-time application traffic so i think may be performance when HTB \
manage real-time application are not work if i comparable </P> <P>with performance by \
HFSC"</P> <P>so my project is ... i want to develop new traffic shaper that use 2 \
algorithm simultaneously (HTB for manage general traffic and HFSC for manage only \
real time application) </P> <P>by when the package come in my shaper outbound i will \
have one filter for <BR>filtering that package about what kind of that \
package??(general or real time application package) and then after filtering it will \
continue send that package to appropriate </P> <P>queue to separate manage traffic \
later.</P> <P>sorry for my bad english so much <BR>may be you don't understand my \
project topic so looking in my picture. </P> \
<P><BR> \
(general package)<BR> \
outbound \
------------------------- HTB<BR>------eth0----------- filter \
<BR> \
\
------------------------- HFSC<BR> (real time \
application package) </P> <P>now my problem is... i read a lot paper they tell \
if i want to use traffic shaper in outbound side. In linux i must use tc command for \
setting it, but it's telling me about setting </P> <P>algoritm will start to set in \
root qdisc and root qdisc is outboud side<BR>so i fear about i can't setting 2 \
algorithm simultaneously in tc command</P> <P> </P>
<P>so please advise me , if you think i'm misunderstand and Is it can do for real??? \
what should i do???</P> <P><BR>my question<BR>1. In tc command, at root qdisc we must \
specify what kind of algorithm to use??(htb or etc) ????<BR>Ex. tc qdisc add dev eth0 \
root handle 1: "htb"<BR>-Is it important and must specify algorithm in above \
command??? and can i define algorithm later??<BR>-If i use above command, another \
class under that root qdisc must be only HTB algorithm????? <BR>Can be HFSC,CBQ \
etc??? what should i do it???</P> <P>2. About linux traffic control \
atchitecture theory, Is it true or false???(It's only my assumption)<BR>Can i define \
new qdisc under root qdisc????<BR>Because from theory, we define class under qdisc. \
</P> <P>this is my assumption<BR>tc qdisc add dev eth0 root handle 1: fifo <BR>tc \
qdisc add dev eth0 parent 1: classid 10:1 htb rate 100kbps ceil 100kbps<BR>tc qdisc \
add dev eth0 parent 1: classid 10:2 hfsc rate 100kbps ceil 100kbps</P> <P>2. i want \
to have two different qdisc for run simultaneously??(HTB and HFSC) Can i do it for \
real????<BR>if i can, so what should i do it with tc command?????</P> <P>3. In the \
one time, Outbound traffic Linux can setting to have 2 root qdisc ????</P> <DIV \
