Hello, Besides a very good functionality, I have a small, yet stressing, problem. Let's say I have a bandwidth of N bits. I have X clients, everyone with his fixed bandwidth. I create htb qdsics for each client. Each leaf has sfq queueing discipline. A sample config would be like this : tc class add dev eth0 parent 1:2 classid 1:346 htb rate 32Kbit ceil 32Kbit burst 4k cburst 2k prio 4 tc qdisc add dev eth0 parent 1:346 handle 346 sfq perturb 10 AND tc class add dev eth0 parent 1:2 classid 1:161 htb rate 256Kbit ceil 256Kbit burst 32k cburst 2k prio 4 tc qdisc add dev eth0 parent 1:161 handle 161 sfq perturb 10 The filters are like : tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match ip dst 1.2.3.128/25 classid 1:346 tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match ip dst 1.2.3.4/30 classid 1:161 The problem is that clients can have their bandwidths at maximum only if they use a download accelerating software like DAP with multiple symultanous threads. Using only one thread, a single download can reach about 60% of the allocated bandwidth. I have tested a download without any limits and it was working well, so there's no problem with the remote site. I have searched thorugh messages posted on this mailing list but I didn't find a similar problem. Maybe I need to set quantum manually. I have tested with r2q default value (10) and also with 2 (raising quantum). Another question would be: if quantum is bigger, the client can exceed his limit by that value ? Is that possible all the time or at bursty intervals ? Thank you very much, Ciprian Nica _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
