r> hello again,

r> I got some just preliminary results .... hope someone can explain them to me...
r> As I already told I have the following config :

r> egress {

r>         class (50kbps) {sfq};
r>         class (80kbps) {sfq};
r>         class (30kbps) {sfq};
r>         class (50kbps) {sfq};
r>         ...hundreds like this...
r>         class (10kbps,default) {sfq};
r> }

r> What I got is traffic starvation very often for a period of  ~30 sec.. as proposed I've done :

r> egress {
r>         ...hundreds classes...
r>         class (10kbps, prio 7, default) {sfq};
r> }

r> It seemed a litlle bit better the starvation seemed to be just ~10sec but this time happen much often...
r> then I made a final touch :

r> egress {
r>         ...hundreds classes...
r>         class (55kbps, prio 7, default);
r> }

r> No "sfq" this time and it seemed much much better now...
r> I have done my tests mostly with :

r> hping2 host-behind-qos --fast --icmp
r> fping host1 host2 -l

r> I made second and third test for very short periods of time so this is not a final "say" of the success...

r> ------------ ?! SO COULD U EXPLAIN ME WHY THIS HAPPEN ?! --------------------------

r> And most importantly is there a better solution, I don't know what will happen if I want more complex solution but not this flat structure...
r> Or at least give me some directions how to go further and eradicate this "STARVATION" problem..

r> Can I lower "class (55kbps, prio 7, default);" to "class (10kbps, prio 7, default);" .... 
r> Giving more bandwith to DEFAULT class is not solution but a ANTI-SOLUTION, my idea is not to give all my bandwith to spammers and viruses :")

r> Expecting explanation :"))
