I would not agree to the half of your statments.

Yes. -------- This is incorrect: of course it will work more or less, but nearly same as without any shaping > Q3.

Will HTB work correctly? Yes. ----- For certain this is wrong, I dont understand why you say so, because everybody knows that you must limit ceil to a bit lover than you get from isp if you have unknown trafic you cant limit it. > Q4.

The RATE, or the QUANTUM? > (e.g. ClassA---QUANTUM 3000---RATE 8kbit, or > ClassB---QUANTUM 1500---RATE 16kbit) r2q is used to calculate the default quantum of a class: quantum =ate / r2q But you can overrule this default quantum when you add a class. ------ quantum is more powerfull and usefull. since rate of 8kbit is insignificant speed anyway but it may be harder to calculate( didt tested if quantum can completely replace rate effect) in your example class A will get 2 times more bandwitch than class B > Q5. The HTB Manual says that the sum of the LEAF CLASSES RATE must be > equal to the PARENT CLASS RATE. Is there such a rule for QUANTUMS? No ---- seems correct, htb manual says nonsense, neither rates nether quantums need to be equal, but child sum rates and quantums ONLY SHOULD be less or equal to parent. quantums for schild basicaly should be not higer than parent quantums, else result may be starange. this indirectly may affect the statment from htb manual, because rate affect quantums. and if one child will consume all its parent quantum then other childs may get nothing.
