Hi,All I setup traffic control configuration with HTB this way: 1: root HTB qdisc | 1:1 HTB class rate 1024kbit | /-----+-----+-----+------+-----\ 1:10 1:20 1:30 1:40 1:50 1:60 EF AF41 AF31 AF21 AF11 BE and alloct different bandwidth to these PHBs(queues).So which tool would I use to generate these packets at the same to for testing?Thank you! Another question:I am studying sch_htb.c,but it's so tough for to understand,especially htb_dequeue().Would anyone please supply some adivse? Thank you very much!
