Hi Mohan thanks for the brief explanation... about the IMQ so when IMQ should be used when the both in/out traffic same ? like fixed ( 64kbps, irrespective of in and out) or like IN is less and OUT is more ? or IN more and OUT less ? ( like 32 up and 32 down or 16 up and 48 down) thanks hare ----- Original Message ----- From: "S Mohan" <smohan@xxxxxxxx> To: <lartc@xxxxxxxxxxxxxxx> Sent: Tuesday, March 04, 2003 11:57 AM Subject: RE: [LARTC] Need some help on HTB and IMQ > > This question comes up pretty often.
