low network latencies to function properly. If bandwidth is being used by other
applications such as an FTP server, users using VoIP will experience network lag
and/or service interruptions during use. To avoid this scenario, this network has
assigned VoIP with a guaranteed bandwidth and higher priority to ensure smooth
communications. The FTP server, on the other hand, has been given a maximum
bandwidth cap to make sure that regular service to both VoIP and normal Internet
applications is uninterrupted.
2.2.3 Guaranteed / Maximum Bandwidth
Setting a Guaranteed Bandwidth ensures that a particular service receives a
minimum percentage of bandwidth. For example, you can configure BiGuard 30 to
reserve 10% of the available bandwidth for a particular computer on the network to
transfer files.
Alternatively you can set a Maximum Bandwidth to restrict a particular application
to a fixed percentage of the total throughput. Setting a Maximum Bandwidth of 20%
for a file sharing program will ensure that no more than 20% of the available
bandwidth will be used for file sharing.

Policy Based Traffic Shaping allows you to apply specific traffic policies across a
range of IP addresses or ports. This is particularly useful for assigning different
