Thank you for replying!

I find that POLICE_SPEC (term from tc command syntax, not found in the
HOWTO) isn''t very well or perhaps clearly documented. I figure the
first
page you sent is trying to say is that the syntax is more or less:

POLICE_SPEC = police [buffer [buffer] | maxburst [maxburst]] [mtu [mtu]
| minburst [minburst]] [mpu [mpu]] [rate [rate]] (continue | drop | pass
| reclassify)

However, the examples you sent are using parameter "burst" not listed
above. A novice as myself can find learning Linux traffic control a bit
confusing with this kind of discrepancies between the HOWTO, the command
syntax and the man pages.

>I''m not sure where examples are of ''estimator''
usage.

If someone else here knows, please do tell.
