5.8 iDBM

iDBM SETUP

Intelligent Bandwidth Management (iDBM) provides two powerful and unique
mechanisms to manage bandwidth: Static Bandwidth Management (SBM) and
Dynamic Bandwidth Management (DBM). SBM provides users with the option to
allocate a fixed amount of bandwidth for a specific computer or a particular
application, while DBM intellectually manages the rest of the bandwidth while all the
time satisfying the complicated bandwidth requirements/settings of SBM.

iDBM Settings

The essential configuration needed by iDBM is to specify accurately the bandwidth
you have. iDBM would then dispatch bandwidth according to this information. Please
Note: Improper bandwidth assignment may cause iDBM to work ineffectively.

Click on [Bandwidth] – [iDBM] tab. You will see the following screen.
