Hello. I have the fallowing stats when I write: ----tc -s -d qdisc ls dev eth1 ------ "qdisc htb 1: r2q 1 default 99 direct_packets_stat 358 ver 3.7 Sent 36115119 bytes 32068 pkts (dropped 0, overlimits 47848) backlog 24p" 1. what does backlog 24p means here ? 2. I looked over my other htb classes in eth1 and never seen overlimits greater than 0, why do I have then overlimits in htb root ?. Does anyone can tell me more explicitly what overlimits is ? 3. And another thing if I could ask ;-) . Here is part of my htb log : "HTB init, kernel part version 3.7 Nov 30 02:37:23 Rout-Raul kernel: HTB init, kernel part version 3.7 Nov 30 02:37:27 Rout-Raul kernel: HTB: quantum of class 10099 is small. Consider r2q change.<4>HTB: quantum of class 10099 is small. Consider r2q change.<7>htb*g j=89425972" I have my r2q set to 1..I''m using a formula like r2q=LEAF_RATE/8*1000/1600. I was recommended by someone to use it. I really don''t know why. Any suggestions ?
