...ere in the code) 2. Why does htb calculate its burst(buffer) with tc_xmit_time() ? Is opt.rate.buffer supposed to have the time it takes to transmit the packet ? (in q_htb.c around 223 lines) 3. What does rtab and ctab arrays do ? And what kind of value should be in there ? (its set in tc_core.c tc_calc_rtable()) I''d really appreciate your help. Thankyou very much in advance.

Hi. I wrote in a reply to a mail on here recently that you can''t set mpu (minimum packet unit) on HTB as you can on CBQ. I''ve just noticed that there is a patch on devik''s site which does mpu and overhead. http://luxik.cdi.cz/~devik/qos/htb/ For dsl users mpu is, for practical purposes going to be 106 - overhead is still variable though, depending on packet size.

OK, here it is. Near perfect bandwidth calculation for ADSL users. Patch iproute2 with the HTB stuff and then this: It''s still a hack (as far as I can tell) because we are patching the rates tables, and hence I think it is only loosly coupled with the actual calculation of bytes in each bucket. However, it works very nicely for me! I have only been lightly testing with
