<html><div style='background-color:'><DIV class=RTE><BR>I have a lot question about tc-command because now i'm doing research to compare </DIV>
<DIV class=RTE>performance between HTB and HFSC </DIV>
<DIV class=RTE>so i'm doubt a lot thing and your reply are so very helpful to me ... My question is </DIV>
<DIV class=RTE> </DIV>
<DIV class=RTE><STRONG>In HTB tc command question</STRONG><BR>1. I'm use opensource (Mastershaper) for help to config traffic control </DIV>
<DIV class=RTE>but when i'm try to config HTB,<BR>I'm doubt about in each chain must identify fallback service level </DIV>
<DIV class=RTE>and If i'm don't specify it,it will unable to contain pipe. </DIV>
<DIV class=RTE>Every traffic and if traffic not matched in chain's pipe can only use the fallback service level</DIV>
<DIV class=RTE>
<DIV class=RTE>(ps. Mastershaper represent interior class as pipe and leaf class as chain)</DIV></DIV>
<DIV class=RTE> </DIV>
<DIV class=RTE>Is it only true definition in HTB tc command?? or it's only a creative function from developer??</DIV>
<DIV class=RTE> </DIV>
<DIV class=RTE><STRONG>In HFSC tc command question </STRONG></DIV>
<DIV class=RTE>after i read HFSC paper , i'm doubt in Service curve declaration like this</DIV>
<DIV class=RTE>> | SC := [ [ m1 BPS ] [ d SEC ] m2 BPS<BR>> | <BR>> | m1 : slope of first segment -> umax<BR>> | d : x-coordinate of intersection -> dmax<BR>> | m2 : slope of second segment -> rate</DIV>
<DIV class=RTE> </DIV>
<DIV class=RTE>2. In all leaf class must specify rt (realtime service curve) ??? and Is it important to </DIV>
<DIV class=RTE>specify sc (Service curve) in all leaf class ?? and in all leaf class must specify link-sharing (ls) too??</DIV>
<DIV class=RTE>because i think after read HFSC theory about by default All leaf class(Service class)</DIV>
<DIV class=RTE>will use Link-sharing critirion for allocation bandwidth from Service curve </DIV>
<DIV class=RTE>(My assumtion think this calculation bandwidth is "m1" or "umax" ->total bandwidth </DIV>
<DIV class=RTE>that can send at ceil rate??) and when total delay are exceed to "demax" or "d" -> it mean </DIV>
<DIV class=RTE>it's time for HFSC to manage QoS to guarantee bandwidth and delay</DIV>
<DIV class=RTE>in each leaf class by use Real-time Criterion so bandwidth rate will change to "m2" </DIV>
<DIV class=RTE>or bandwidth rate that guarantee QoS in eache leaf class<BR></DIV>
<DIV class=RTE>Is it true??? i fear may be misunderstand in HFSC theory,<BR></DIV>
<DIV class=RTE>example in my test lab ,i have leaf class 3 type such real-time ,data ,default<BR>Can i specify <BR> - real-time leaf class -> rt (for guatantee delay and bw) ,ls (by default when not exceed max delay)<BR> - data lead class -> ls (by default and not delay sensitive so delay are not important)</DIV>
<DIV class=RTE><BR>3. I'm doubt in How to declaration ls, and ul about .. in thoery it a type of service curve that not</DIV>
<DIV class=RTE>relative with real-criterion, so Delay may be not important for consider ???? <BR></DIV>
<DIV class=RTE>Is it true when declaration, parameter in each service curve may be link this?<BR> ls [ umax BPS, rate BPS]<BR> ul [ umax BPS, rate BPS]<BR></DIV>
<DIV class=RTE>and </DIV>
<DIV class=RTE>Is it important to declaration all of three parameter (umax,demax,rate) If three parameter<BR>are important to setting traffic control????</DIV>
<DIV class=RTE> </DIV>
<DIV class=RTE>3. I'm try to search HFSC command example, it have a lot case but i'm doubt in service curve (sc)</DIV>
<DIV class=RTE>declaration sometime declaration in root class, interior class, in leaf class<BR>so I'm not sure to understand about ls ->calculate bandwidth for interior class,root class and <BR>rt -> calculate bandwidth for leaf class and what about service curve(sc)??? it's specify only in root class???</DIV>
<DIV class=RTE> </DIV>
<DIV class=RTE>4. Is it true?? <BR>In root class, or interior class will doing with only Link-sharing criterion, so can specify declaration</DIV>
<DIV class=RTE>only link-sharing ->ls(umax, dmax, rate) and Upperlimit ->ls(umanx,dmax,rate) it's not important </DIV>
<DIV class=RTE>to declaration real-time curve (rt) because in HFSC theory will use real-time criterion only Leaf class</DIV>
<DIV class=RTE> </DIV>
<DIV class=RTE>5. In HFSC, upper limit are bandwidth rate that guarantee maximum bandwidth rate in </DIV>
<DIV class=RTE>each class as ceil in HTB???</DIV>
<DIV class=RTE> </DIV>
<DIV class=RTE>6. I'm doubt about priority in HFSC, in HFSC paper telling about in support priority </DIV>
<DIV class=RTE>but in HFSC tc-command it not specify priority in each class, </DIV>
<DIV class=RTE>So In HFSC how to manage priority class link HTB????</DIV>
<DIV class=RTE><BR>Thank you for all reply, it's so very helpful to me alot.<BR>which all will suggest or advise me about in something i'm misunderstand </DIV>
