As illustrated in the diagram above, applications such as Voiceover IP (VoIP) require 
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 2/10 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.
