Have you fully read:
http://lartc.org/howto/lartc.qdisc.classless.html#AEN691
?
most of it is explained in there.
1) What unit is token? Is "1 token = 1 byte" ?
If this is so, then with rate=0.5mbit and HZ=100 the bucket gets filled
with 0,64kb (655 tokens) every 10ms?
1 token is one packet.
2) How much tokens are used for one packet (1500)?
1
3) And token unrelated question. Does packet droping alway ocurrs or
it happens because of bad settings?
I have applied this settings on 10mbit ethernet card:
tc qdisc add dev eth1 root tbf rate 0.5mbit burst 5kb latency 70ms /
peakrate 1mbit minburst 1540
Result:
qdisc tbf 8007: dev eth1 rate 512Kbit burst 5Kb/8 mpu 0b peakrate 1Mbit mtu
1539b/8 mpu 0b lat 68.4ms
Sent 1284481 bytes 852 pkts (dropped 48, overlimits 1743)
Packet dropping happens when too much data is coming in.
See the explanation in the link above.
