Hello! I have a quite complicated setup. In my network on each interface there is bandwidth limitation for each user. Booth outgoing (on interface itself) and incoming (attached IMQ) traffic. There is main HTB class which limits bandwidth for whole interface and HTB subclasses for each user. Filtering is done with hashing filters. This setup was working correctly. But now in the network I have a DC hub (p2p) which allows user to exchange files. The problem is that I want in-network p2p connections to be faster than Internet bandwidth (and not "eating" their Internet bandwidth) and also I want in-network connections to have lower priority in borrowing the link bandwidth (I am using radio links between network segments and having "good" Internet access is priority over local traffic). Here is current setup: tc qdisc del root dev eth2.24 2>/dev/null tc qdisc add root dev eth2.24 handle 1: htb default 1 # main rate limitation for whole connection (802.11a radio link) tc class add dev eth2.24 parent 1: classid 1:1 htb rate 15000kbit ceil 15000kbit burst 10kbit # class for internet connections - this one can use nearly whole link tc class add dev eth2.24 parent 1:1 classid 1:6667 htb rate 12000kbit ceil 13500kbit burst 100kbit # class for in-network p2p connections - this one has lower guaranteed rate tc class add dev eth2.24 parent 1:1 classid 1:6666 htb rate 3000kbit ceil 14000kbit burst 10kbit tc qdisc add dev eth2.24 parent 1:6666 handle 6666: sfq perturb 5 quantum 1500b # users (htb+sfq for each): tc class add dev eth2.24 parent 1:6667 classid 1:2 htb rate 1kbit ceil 256kbit quantum 2000 burst 100kbit tc qdisc add dev eth2.24 parent 1:2 handle 2: sfq perturb 5 quantum 1500b tc class add dev eth2.24 parent 1:6667 classid 1:3 htb rate 1kbit ceil 256kbit quantum 2000 burst 100kbit tc qdisc add dev eth2.24 parent 1:3 handle 3: sfq perturb 5 quantum 1500b .... .... tc class add dev eth2.24 parent 1:6667 classid 1:1006 htb rate 1kbit ceil 384kbit quantum 2000 burst 100kbit tc qdisc add dev eth2.24 parent 1:1006 handle 1006: sfq perturb 5 quantum 1500b (some hashing filters - which I think are working properly, so not shown here) # traffic going to these networks goes to hashing filters tc filter add dev eth2.24 protocol ip parent 1:0 u32 match ip dst 192.168.1.0/24 hashkey mask 0x000000ff at 16 link 2: $TC filter add dev eth2.24 protocol ip parent 1:0 u32 match ip dst 192.168.3.0/24 hashkey mask 0x000000ff at 16 link 3: # now in-network p2p traffic. if it comes from other LANs then direct it to # 1:6666 tc filter add dev eth2.24 protocol ip parent 1:0 u32 match ip src 192.168.5.0/24 flowid 1:6666 tc filter add dev eth2.24 protocol ip parent 1:0 u32 match ip src 192.168.4.0/24 flowid 1:6666 Filters look OK. AFAIK the last filter is the most important so even trafiic to 192.168.1.0/24 but comming from 192.168.5.0/24 will go to 1:6666 instead of hashing filters and user bandwidth HTB. The hashing filtes were working on previous setup and now users still have their proper bandwidth from the Internet. Here is the graph representing the traffic: http://tuxpowered.net/lan_p2p/lan_eth1_rx_dzien.png the colors are: #ff00ff - htb 1:6666 (LAN p2p) #00ff00 - htb 1:6667 (Internet) #000000 - real interface traffic (tc -s li show ethXX) And now description of the problem: Class 1:6666 never has more traffic than 'rate'. AFAIK it should be having 'rate' as minimum guaranted rate and going up to 'ceil' if there is free bandwidth. (directing LAN traffic to 1:1 works OK - look at the graph at about 14:45 - 14:55) Bandwidth sharing setup works for me on WAN interfaces, but there I have only 1 level of classes tree. Here are 2 levels and it is not working. What I want: .---------------------------------. | 1:1 rate = ceil = link bandwidth| `---------------------------------' | | .--------------------. .-------------------------. | 1:6666 p2p traffic | | 1:6667 Internet traffic | | low priority in | | high prioriy in | | badwidth sharing: | | bandwidth sharing: | | ceil =~ from 1:1 | | ceil =~ from 1:1 | | rate = small | | rate = (from1:1)-1:6666 | `--------------------' `-------------------------' | +-- 1:2 user rate=1kbit ceil=256kbit +-- 1:2 user rate=1kbit ceil=256kbit ..... +-- 1:1203 user rate=1kbit ceil=384kbit -- | pozdrawiam / greetings | powered by Trustix, Gentoo and FreeBSD | | Kajetan Staszkiewicz | JID: vegeta@xxxxxxxxx | | Vegeta | IMQ devnames: http://tuxpowered.net | `------------------------^----------------------------------------' _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
