Mission-critical application

Mostly the VPN connection is mission-critical application for doing data exchange between head and

branch office.

The mission-critical application must be sent out smoothly without any dropping. Set priority as high level

for preventing any other applications to saturate the bandwidth.

Voice application

Voice is latency-sensitive application. Most VoIP devices are use SIP protocol and the port number will

be assigned by SIP module automatically. Better to use fixed IP address for catching VoIP packets as

high priority.

Above settings will help to improve quality of your VoIP service when traffic is full loading.

Restricted Application

Some of companies will setup FTP server for customer downloading or home user sharing their files by

using FTP.

With above settings that help to limit utilization of upstream of FTP. Time schedule also help you to only

limit utilization at daytime.

Advanced setting by using IP throttling

With IP throttling you can specify more detail for allocating bandwidth; even the applications are located

in the same level.

Upstream: 928kbps (29*32kbps)

Mission-critical Application: 192kbps (6*32kbps

Voice Application: 128kbps (4*32kbps)

Restricted Application: 160kbps (5*32kbps)

Other Applications: 448kbps (14*32kbps)

6+4+14+5=29, 29*32kbps=928kbps

Sometime your customers or friends may upload their files to your FTP server and that will saturate your

downstream bandwidth. The settings below help you to limit bandwidth for the restricted application.
