Subject: [LARTC] Help please on HTB vs CBQ for shaping on a 10Mbit link and igress
Date: Fri, 20 Jun 2003 07:49:19 +0000	[thread overview]
Message-ID: <marc-lartc-105609548112046@msgid-missing> (raw)

I am setting up some traffic shaping on a 10Mbit (bursting to 20Mbit) 
link. with various class rates from 2Mbit to 6Mbit
My router is Intel (1GHz processor)

I have configured my script using HTB, however from reading the 
documentation HTB appears to be using the same alogorithm as TBF, and 
TBF is only effective up to 1Mbit.

Should I be be re-scripting to use CBQ?

I am also using igress shaping ( without IMQ )  and the filter 
alogroriths are also TBF .

Can anyone recommend a workable rule for the ratio between rate and 
burst for higher bandwidths? - it looks to me as though it should be 
around 22:1

Does the "latency" parameter cause packets to be dropped when they have 
been waiting more than latency ms?


TIA,
Derek
