[LARTC] tc+udp priority

[George Tsuladze]

here is my skript.
i want to priorize on  first udp second icmp then tcp then any other how?
does "tc qdisc add dev eth0 parent 1:12 handle 20: prio 1 udp " priorize 
udp?

tc qdisc del dev eth0 root
tc qdisc del dev eth1 root
#eht0 rules
tc qdisc add dev eth0 root handle 1: htb default 12
#shape interface eth0
tc class add dev eth0 parent 1: classid 1:1 htb rate 128kbit ceil 128kbit
#voip class
tc class add dev eth0 parent 1:1 classid 1:12 htb rate 128kbit ceil 128kbit
#staff class
tc class add dev eth0 parent 1:1  classid 1:11 htb rate 30kbit ceil 128kbit
tc class add dev eth0 parent 1:1  classid 1:13 htb rate 30kbit ceil 128kbit
#mark voip class
tc filter add dev eth0 parent 1: protocol ip prio 1 handle 2 fw classid 1:12
#mark staff class
tc filter add dev eth0 parent 1: protocol ip prio 1 handle 1 fw classid 1:11

not exactly - default prio is 0 (highest). Use prio 3 for 1:11,1:10
and prio 1 for 1:12 and prio 2 for icmp class.

this is nonsence ! 128+30+30 > 128. You guarantee 208kb while
1:1 has only 128k capacity ...

first class (1) is working on voip
second (2) is just staff

I have 512kbit connection. i am doing the following. giving both class 
512 kbps. but if voip needs 512 it can get it all 512. and staff will 
get nothing.  if voip only use 300 staff can use 212 kbps. 128 kbit was 
an example not my real speed. so as a rule voip uses udp protocol. thats 
because i want to priorize udp protocols. in voip class i want to 
priorize udp, then icmp then any other. in staff clas i want to priorize 
first udp then icmp then tcp then any other. how can i add this? and 
does my script solves my problem? i sought that i have to create 2 class 
voip and staf. then make subclasses in voip and staff. like voip classid 
1:1 and staf classid 1:2  then this clasids must have there classes voip 
and staff. i think it is better for traffic shaping. hint me how can i 
do it. and can  i do the following give to 1:1 classid rate 512 and ceil 
512. so voip can use all bandwith.
 and give to 1:2  rate 2    ceil 512.  does it mean that if 1:1 classes 
use 400 kb 1:2 classes can use 112 kb? and can i borrow  112 kbps in 1:2 
classes. i mean that if 1 pc from 1;2 classes use all 112 and 2 pc-s 
want tu use one 30 second 12 fisrt will use only 60 kb. that is my 
problem. and please hint my with some examples hopw can i do it.
