Using Bandwidth Management
Why Bandwidth Management (BWM)?
Nowadays, we have many different traffic types for Internet applications. Some traffic may consume high
bandwidth, such as FTP (File Transfer Protocol), if you are downloading or uploading files with large size.
Some other traffic may not require high bandwidth, but they require stable supply of bandwidth, such as
VoIP traffic. The VoIP quality would not be good, if all of the outgoing bandwidth is occupied via FTP.
Additionally, chances are that you would like to grant higher bandwidth for some body special that is
using specific IP address in your network. All of these are reasons why we need bandwidth management.
