now, i'm learning and try to read a lot of article about tc command in linux for setting traffic shaper.but i'm doubt aboutIn the theory about tc command ... In general, we define class under root qdiscbut Is it can be possible If we define another qdisc under root qdisc, Can i do it?because i have just read tc command syntax and i found this point ...
syntax: tc qdisc [add/del] dev String[handle][root /ingress/ parent CLASSID][QDISC_KIND] := {fifo /tbf/ prio/ cbq/ htb/ hfsc}
from above syntax at [handle][root /ingress/ parent CLASSID]
Is "parent CLASSID" mean we can define qdisc under classso this is my assumption about that. and Could you advise me about Is it can do for real
//first .. define root qdisctc qdisc add dev eth0 root handle 1: fifo
//second ... define class under root qdisc but algorithm's not same like root qdisc algorithmtc class add dev eth0 parent 1: classid 1:1 htb rate 100kbps ceil 100kbpstc class add dev eth0 parent 1: classid 1:2 hfsc rate 100kbps ceil 100kbps

[LARTC] HTB and HFSC,declaration tc command question
I have a lot question about tc-command because now i'm doing research to compare performance between HTB and HFSC so i'm doubt a lot thing and your reply are so very helpful to me ... My question is In HTB tc command question1. I'm use opensource (Mastershaper) for help to config traffic control but when i'm try to config HTB,I'm doubt about in each chain must identify fallback service level and If i'm don't specify it,it will unable to contain pipe. Every traffic and if traffic not matched in chain's pipe can only use the fallback service level (ps. Mastershaper represent interior class as pipe and leaf class as chain) Is it only true definition in HTB tc command?? or it's only a creative function from developer?? In HFSC tc command question after i read HFSC paper , i'm doubt in Service curve declaration like this | SC := [ [ m1 BPS ] [ d SEC ] m2 BPS | | m1 : slope of first segment - umax | d : x-coordinate of intersection - dmax | m2 : slope of second segment - rate 2. In all leaf class must specify rt (realtime service curve) ??? and Is it important to specify sc (Service curve) in all leaf class ?? and in all leaf class must specify link-sharing (ls) too?? because i think after read HFSC theory about by default All leaf class(Service class) will use Link-sharing critirion for allocation bandwidth from Service curve (My assumtion think this calculation bandwidth is "m1" or "umax" -total bandwidth that can send at ceil rate??) and when total delay are exceed to "demax" or "d" - it mean it's time for HFSC to manage QoS to guarantee bandwidth and delay in each leaf class by use Real-time Criterion so bandwidth rate will change to "m2" or bandwidth rate that guarantee QoS in eache leaf class Is it true??? i fear may be misunderstand in HFSC theory, example in my test lab ,i have leaf class 3 type such real-time ,data ,defaultCan i specify - real-time leaf class - rt (for guatantee delay and bw) ,ls (by default when not exceed max delay)- data lead class - ls (by default and not delay sensitive so delay are not important) 3. I'm doubt in How to declaration ls, and ul about .. in thoery it a type of service curve that not relative with real-criterion, so Delay may be not important for consider Is it true when declaration, parameter in each service curve may be link this?ls [ umax BPS, rate BPS]ul [ umax BPS, rate BPS] and Is it important to declaration all of three parameter (umax,demax,rate) If three parameterare important to setting traffic control 3. I'm try to search HFSC command example, it have a lot case but i'm doubt in service curve (sc) declaration sometime declaration in root class, interior class, in leaf classso I'm not sure to understand about ls -calculate bandwidth for interior class,root class and rt - calculate bandwidth for leaf class and what about service curve(sc)??? it's specify only in root class??? 4. Is it true?? In root class, or interior class will doing with only Link-sharing criterion, so can specify declaration only link-sharing -ls(umax, dmax, rate) and Upperlimit -ls(umanx,dmax,rate)it's not important to declaration real-time curve (rt) because in HFSC theory will use real-time criterion only Leaf class 5. In HFSC, upper limit are bandwidth rate that guarantee maximum bandwidth rate in each class as ceil in HTB??? 6.
