Hi all!
I'm working in a " _really_ end user simple", yet powerfull, flexible,
scalable, GPL htb/htb-init front end, but now, in the "test fase" im facing
an utlimate problem...
Absoult minimalistic scenario: #Use a FIXEDFONT to read this
#inet-ethx-|FIREWALL|-lan-ethx <-> |client_host_1|
#
#FIREWALL class(rate,ceil) at lan-ethx
root->parent_all_host(256,256)->client_host_1(X,X)->host_1_prio(X*0.9,X)
->host_1_dfl(X*0.1,X)
then i genrate equal traffic for the to leafs and:
if X<=200 then "all works ok"
the 'prio' class takes 90% of the rate
the "dfl" class takes 10% of the rate
if X>230 then "all works like no htb present at all"
the 'prio' and 'dfl' class figth equaly for the rate
Things that i have tried that don't help to solve the problem:
-Play with several r2q/quantum convinations
-Play with prio parameter for the leafs
-Tray thiferent leaf's algo(sfq with quantum 1500,pfifo with limit 10)
-change parent_all_hosts rate to a high value (ie:512,1024)
I've attached simplified ad-hoc scripts that reproduce the scenarios:
tc_at_200 (full tc/iptables commands to recreate the X<200 scenario)
tc_at_230 (full tc/iptables commands to recreate the X>200 scenario)
To test i run in the client_host_1 2 lftp instances ie:
lftp -c "pget -n ftp://somehost/very.long.file"; #4 tcp conns "stress" ;-)
lftp -c "get http://samehost/very.long.file";
note that first generates ftp traffic while second one is http traffic, the
firewall marks will make that http goes in 'prio' class and ftp goes in 'dfl'
class. I leave this traffic running...
if i run ./tc_at_200 everithing goes to its place
if i run ./tc_at_230 everithing goes wrong, the 4 ftp's 'dfl' traffic
connection monopolice at lest 80% of the total rate.
if i run ./tc_at_200 everithing goes to its place again
and so on...
Whell hope someone give me a hint on this!
