If this is really all of your script, you are missing the filter rules 
which match your
traffic and put it in your classes...

[LARTC] FW: HFSC + ESFQ - class statistics

[Forte Systems - Iosif Peterfi]

[-- Attachment #1.1: Type: text/plain, Size: 3118 bytes --]

Hello, 

 

            First I want to point out that I'm not so familiar with HFSC,
since there not so much info online.

            But here is my script:

 

        ${TC} class add dev ${LAN_IFACE} parent 1:0 classid 1:1 hfsc ls rate
100mbit ul rate 100mbit

 

        ${TC} class add dev ${LAN_IFACE} parent 1:1 classid 1:2 hfsc ls rate
90mbit ul rate 90mbit

        ${TC} class add dev ${LAN_IFACE} parent 1:1 classid 1:3 hfsc ls rate
690kbit ul rate 690kbit

 

        ${TC} class add dev ${LAN_IFACE} parent 1:3 classid 1:10 hfsc rt
dmax 1ms rate 32kbit ls rate 690kbit #dns

        ${TC} class add dev ${LAN_IFACE} parent 1:3 classid 1:20 hfsc rt
dmax 2ms rate 256kbit ls dmax 3ms rate 690kbit #http int

        ${TC} class add dev ${LAN_IFACE} parent 1:2 classid 1:25 hfsc rt
dmax 100ms rate 10mbit ls dmax 100ms rate 80mbit #squid

        ${TC} class add dev ${LAN_IFACE} parent 1:2 classid 1:30 hfsc rt
dmax 200ms rate 80kbit ls dmax 500ms rate 80kbit #wan

        ${TC} class add dev ${LAN_IFACE} parent 1:3 classid 1:40 hfsc rt
dmax 20ms rate 32kbit ls dmax 500ms rate 690kbit #msn

        ${TC} class add dev ${LAN_IFACE} parent 1:3 classid 1:50 hfsc rt
dmax 200ms rate 32kbit ls dmax 500ms rate 690kbit # http bulk

        ${TC} class add dev ${LAN_IFACE} parent 1:3 classid 1:60 hfsc rt
dmax 500ms rate 32kbit ls dmax 3000ms rate 690kbit # the rest

 

        ${TC} qdisc add dev ${LAN_IFACE} parent 1:10 handle 10: esfq hash
dst perturb 10

        ${TC} qdisc add dev ${LAN_IFACE} parent 1:20 handle 20: esfq hash
dst  perturb 10

        ${TC} qdisc add dev ${LAN_IFACE} parent 1:25 handle 25: esfq hash
dst  perturb 10

        ${TC} qdisc add dev ${LAN_IFACE} parent 1:30 handle 30: esfq hash
dst  perturb 10

        ${TC} qdisc add dev ${LAN_IFACE} parent 1:40 handle 40: esfq hash
dst  perturb 10

        ${TC} qdisc add dev ${LAN_IFACE} parent 1:50 handle 50: esfq hash
dst  perturb 10

        ${TC} qdisc add dev ${LAN_IFACE} parent 1:60 handle 60: esfq hash
dst  perturb 10

 period 16413 work 7651774 bytes rtwork 1120698 bytes level 0

 

        The tc show command doesn't create any sent/rate statistics for  1:
/ 1:1 / 1:2 / 1:3 - Everything is 0 except the period indicators. Sent bytes
are shown in the period, but the rate is not shown. For the rest of the
classes Sent bytes and packets are shown, but rate is not show here either. 

        This bug is related to the kernel or iproute2 package?

        

 

Thanks

Iosif Peterfi

HFSC doesn't update statistics of upper classes because I didn't want to
walk up the entire heirarchy for each packet just for statistics.

Andreas: Of course there are filter rules, but they are irelevant here.

Thanks for the feedback Patrick. I tought so, but i wanted to make sure
there's nothing wrong with my configuration.
