: tc class add dev eth1 parent 30:100 classid 30:1000 \ : htb rate 12800kbps ceil 51200kbps prio 1 : tc qdisc add dev eth1 parent 30:1000 sfq Whoa!! Are you *sure* you mean 12800 kilobytes per second and 51200 kilo bytes per second? Just double-checking. This sort of number looks quite similar to what I call a 128k / 512k line. I would specify these rates as follows: 128kbit and 512kbit But maybe you really mean: 12800kbit and 51200kbit Judging from your "tc -s" output, you have a large pipe to the 'net. : How to do obtain below result: : I read from www.docum.org have problem about parameter: Which parameter are you asking about? You don't provide much information to us about what your question or concern is. Is quantum the problem? Or burst, cburst. : Frist : : : The same story goes for ceil and cburst, you don't want the class to : send more packets then it's ceil allows. So removing the cburst is a : good choice for that case. : : Second: : : Packets that are sent when the class is allowed to send, are still : matched against rate/ceil/burst/cburst. So a big quantum will not : create bursts if you don't allow it with the burs/cburst parameters. Help us understand what your question is, Liang. Thank you, -Martin -- Martin A.
