Hello, thanks Andreas, I reconfigured HTB to get your suggested hierarhy: AK> 1: HTB Qdisc AK> | AK> \--- 1:2 HTB root class (100000Kbit:100000kbit) AK> | AK> \--- 1:2000 HTB leaf class (50000Kbit:100000Kbit) #local AK> | AK> \--- 1:3000 HTB parent class (2048Kbit:2048Kbit) AK> | AK> \--- 1:3010 HTB leaf class (64000bit:256000bit) #ctrl AK> \--- 1:3020 HTB leaf class (128000bit:768000bit) #other AK> \--- 1:3030 HTB leaf class (512000bit:2048Kbit) #www AK> \--- 1:5040 HTB leaf class (386000bit:386000bit) #p2p tc -d class show dev eth0 class htb 1:2 root rate 100000Kbit ceil 100000Kbit burst 51587b/8 mpu 0b overhead 0b cburst 51587b/8 mpu 0b overhead 0b level 7 # local: class htb 1:2000 parent 1:2 leaf 2000: prio 0 quantum 200000 rate 50000Kbit ceil 100000Kbit burst 26593b/8 mpu 0b overhead 0b cburst 51587b/8 mpu 0b overhead 0b level 0 # root for internet trafic class htb 1:3000 parent 1:2 rate 2048Kbit ceil 2048Kbit burst 2623b/8 mpu 0b overhead 0b cburst 2623b/8 mpu 0b overhead 0b level 6 # "ctrl" class class htb 1:3010 parent 1:3000 leaf 3010: prio 1 quantum 1000 rate 64000bit ceil 256000bit burst 1631b/8 mpu 0b overhead 0b cburst 1727b/8 mpu 0b overhead 0b level 0 # "other" class class htb 1:3020 parent 1:3000 leaf 3020: prio 2 quantum 1600 rate 128000bit ceil 768000bit burst 1663b/8 mpu 0b overhead 0b cburst 1983b/8 mpu 0b overhead 0b level 0 # "www" class class htb 1:3030 parent 1:3000 leaf 3030: prio 3 quantum 12800 rate 1024Kbit ceil 2048Kbit burst 2111b/8 mpu 0b overhead 0b cburst 2623b/8 mpu 0b overhead 0b level 0 # "p2p" class class htb 1:5040 parent 1:3000 leaf 5040: prio 4 quantum 1600 rate 128000bit ceil 256000bit burst 1663b/8 mpu 0b overhead 0b cburst 1727b/8 mpu 0b overhead 0b level 0 Sorry to say, results are not as expected. I made new measurements, please see following picture (based on HTB config above): http://elusion.sk/visual_inet_6.png Point A - until now, "p2" clas had CEIL 386 kbit. Now, I reset "p2p" class CEIL to 2048 kbit. As you can see, "p2p" rised as expected Point B - "www" class RATE-CEIL is 512-2048 kbit, "p2p" class RATE-CEIL is 128-2048 kbit. PROBLEM: why did not "www" get more capacity? Point C - "www" class RATE-CEIL is 1536-2048 kbit, "p2p" class RATE-CEIL is 128-2048 kbit. PROBLEM: RATE of "www" is 1536, but class did not get this capacity; "p2p" should fall to it's RATE 256 kbit Point D - "www" class RATE-CEIL is 1024-2048 kbit, "p2p" class RATE-CEIL is 128-2048 kbit - no change Point E - "www" class RATE-CEIL is 1024-2048 kbit, "p2p" class RATE-CEIL is 128-256 kbit - as expected: "p2p" is bounded to 256 kbit limit, so the rest of the capacity was used by "www" class I have expected that in points B, C and D, "p2p" class falls down to it's specified rate and "www" gets most of the capacity. But this is not happening - "p2p" will not fall down Any other things to test, please? Best regards, B.
