Sorry,I means that:
I configure My out interface bandwidth 10kbps.

tc qdisc add dev eth1 root handle 30: htb

http,https traffic from 30:1000 and ftp,ftp-data traffic from 30:2000
I download kernel from www.kernel.org use NetAnts.I noted that rate 200kbps!!!!?
question :
1. I don't know why that rate of NetAnts(200kbps) > out bandwidth(10kbps).
2. I think it maybe dropped packets,but nothing to do .
3. tokens: -317952 ctokens: 243679 what's means about parameters?what's representation positive number or negative number?

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.

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.

Help us understand what your question is, Liang. Thank you,
