CHAPTER9 DYNAMIC BANDWIDTH MANAGEMENT
9.1
DBM SETUP
Bandwidth Management 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.
DBM automatically and consistently monitors bandwidth usage, prioritizes traffic, and allocates bandwidth to all users and
applications. Real-time applications such as
VoIP
,
online gaming
, and
video conferencing
, are granted a higher priority
for bandwidth usage. On the other hand, applications such as
P2P
and
FTP
are given a lower priority. However, when P2P
software is the only application running on the network, DBM is able to provide an efficient allocation and ensure that no
bandwidth is wasted by being able to recognize that it is the only application running. Once real-time applications join the
network, these applications will then immediately have a higher priority to use bandwidth than P2P software. Therefore,
users can play online games, stream network videos, listen to network radio, chat with friends, send e-mails, and run P2P
applications, all at the same time with no disturbances!
9.1.1
DBM Settings
The essential configuration needed by Bandwidth Management is to specify accurately the bandwidth you have.
Bandwidth Management would then dispatch bandwidth according to this information. Please Note: Improper bandwidth
assignment may cause Bandwidth Management to work ineffectively.
