Multi-WAN VPN QoS Router
84
In the boxes for WAN1 and WAN2 bandwidth, input the upstream and downstream bandwidth
which users applied for from bandwidth supplier. The bandwidth QoS will make calculations
according to the data users input. In other words, it will guarantee a minimum rate of upstream
and downstream for each IP and Service Port based on the total actual bandwidth of WAN1 and
WAN2. For example, if the upstream bandwidths of both WAN1 and WAN2 are 512Kbit/Sec, the
total upstream bandwidth will be: WAN1 + WAN2 = 1024Kbit/Sec. Therefore, if there are 50 IP
addresses in the Intranet, the minimum guaranteed upstream bandwidth for each IP would be
1024Kbit/50=20Kbit/Sec. Thus, 20Kbit/Sec can be input for ―Mini. Rate‖ Downstream bandwidth
can be calculated in the same way.
Attention！
The unit of calculation in this example is Kbit. Some software indicates the
downstream/upstream speed with the unit KB. 1KB = 8Kbit.
8.1.2 QoS
To satisfy the bandwidth requirements of certain users, the device enables users to set up
QoS: Rate Control and Priority Control. Users can select only one of the above QoS choices.
Rate Control:
The network administrator can set up bandwidth or usage limitations for each IP or IP range
according to the actual bandwidth. The network administrator can also set bandwidth control for
certain Service Ports. A guarantee bandwidth control for external connections can also be
configured if there is an internal server.
