Hello!
tc-htb is great because its easy, but you cannot specify an mpu. Thats bad,
because with the mpu you can specify the physical characteristics of the
underlying connection. I have a braodband dsl-connection. I have the problem
that the proportion of small packets to big packets changes a lot. So
without specifing the mpu the connection is not to full capacity (big
packets) or the buffer of the modem will be filled (small packets).

Can i append an tc-tbf qdisc (qdisc 30:) to an tc-htb class with specifiying
an mpu? I already did so for increasing the queue for big packets (qdisc
20:), but when i tried this for small packets i could not direct data with
an tc filter to it, it alway go to qdisc 20:.

tc tree Configuration:
    root qdisc htb
        class 1   htb
            class 1:10   htb
                qdisc 20: tbf
            class 1:11 htb
                qdisc 30: tbf

tc filter:
    tc filter add dev $dev protocol ip handle 10 \
        fw flowid 20:
    tc filter add dev $dev protocol ip handle 11 \
        fw flowid 30:


I don=B4t know how those queue work, if you specify the mpu in 20: or 30: w=
ill
the parent classes work with the calculated size of the packets? Anyway,
traffic was not directed in 30: :(

any suggestions?
Great thanks in advance
Alvo
