Mission-critical application
VPN connection is a mission-critical application used for data exchange between head office
and branch office.
This mission-critical application must be sent out smoothly without any dropping. Set this
application as high priority to prevent other applications to saturate the bandwidth.
Voice application
Voice is latency-sensitive application. Most VoIP devices use SIP protocol and the port number
will be assigned by SIP module automatically. It is recommended to set a high priority for
catching VoIP packets with a fixed IP address.
The settings above will help to improve the quality of your VoIP service when the traffic loading
is full.
Restricted Application
Some companies will setup a FTP server for customers to download files or home users to
share their files via FTP.
The settings above help to limit upstream utilization of the FTP. Time schedule feature also
helps to limit daytime utilization.
