Since i appl;ied the patches from Alexej The crashes are gone (there
were same nasty stack overflows when using bounded,isolated classes).
i observe the same results regardless of the `tc qdisc ... sfq ...'
for every class.
my setup is:
#!/bin/sh
tc qdisc add dev eth0 root handle 1: cbq bandwidth 10Mbit allot 1514 cell 8 avpkt 1000
mpu 64
tc class add dev eth0 parent 1:0 classid 1:1 est 250msec 8sec cbq bandwidth 10Mbit
rate 8Mbit allot 1514 cell 8 weight 1Mbit maxburst 20 avpkt 1000 isolated bounded
#bononunu class
tc class add dev eth0 parent 1:1 classid 1:2 est 250msec 8sec cbq bandwidth 10Mbit
rate 5Mbit allot 1514 cell 8 weight 800Kbit maxburst 20 avpkt 1500 split 1:0
tc qdisc add dev eth0 parent 1:2 sfq quantum 1514 perturb 15
#chomsky
tc class add dev eth0 parent 1:1 classid 1:3 est 250msec 8sec cbq bandwidth 10Mbit
rate 1Mbit allot 1514 cell 8 weight 100Kbit maxburst 20 avpkt 1500 split 1:0
tc qdisc add dev eth0 parent 1:3 sfq quantum 1514 perturb 15
#elias
tc class add dev eth0 parent 1:1 classid 1:4 est 250msec 8sec cbq bandwidth 10Mbit
rate 3Mbit allot 1514 cell 8 weight 400Kbit maxburst 20 avpkt 1500 split 1:0
tc qdisc add dev eth0 parent 1:4 sfq quantum 1514 perturb 15
tc filter add dev eth0 parent 1:0 protocol ip route
#bononunu
ip route add 193.46.232.10 dev eth0 flow 0x10002
#chomsky
ip route add 193.46.232.190 dev eth0 flow 0x10003
#elias
ip route add 193.46.232.175 dev eth0 flow 0x10004
and the traffic goes to the correct class, but using netpipe as a
simple throughput test i'm getting:
to bononunu (should be 5Mbit)
66: 4330 bytes 34 times --> 4.00 Mbps in 0.008254 sec
67: 4335 bytes 30 times --> 3.54 Mbps in 0.009332 sec
68: 4340 bytes 26 times --> 4.30 Mbps in 0.007705 sec
69: 4345 bytes 32 times --> 4.20 Mbps in 0.007885 sec
70: 4350 bytes 31 times --> 3.18 Mbps in 0.010432 sec
to chomsky (should be 1 Mbit)
59: 4295 bytes 22 times --> 2.03 Mbps in 0.016122 sec
60: 4300 bytes 15 times --> 1.64 Mbps in 0.019971 sec
61: 4305 bytes 12 times --> 1.62 Mbps in 0.020216 sec
62: 4310 bytes 12 times --> 1.44 Mbps in 0.022760 sec
63: 4315 bytes 10 times --> 2.16 Mbps in 0.015275 sec
and to elias (should be 3 Mbit)
54: 4270 bytes 22 times --> 2.86 Mbps in 0.011390 sec
55: 4275 bytes 21 times --> 2.90 Mbps in 0.011247 sec
56: 4280 bytes 22 times --> 3.49 Mbps in 0.009369 sec
57: 4285 bytes 26 times --> 2.61 Mbps in 0.012517 sec
what i dont't understand is that:
tc -s class show dev eth0
class cbq 1:1 parent 1: rate 8Mbit (bounded,isolated) prio 1
Sent 183336411 bytes 129013 pkts (dropped 0, overlimits 0)
rate 191bps 2pps
borrowed 46807 overactions 0 avgidle 3956 undertime 0
tells me that 1:1 borrows some traffic, although it's isolated and
bounded (i think it shouldn't borrow frm it's ancestores and its
neighbours).
