Tx Traffic Shaping
The bandwidth of a device can be divided in order to reserve constant portions of bandwidth to predefined
traffic types. Such a portion is known as a Shaping Class. When not used by its predefined traffic type, or
owner (for example VoIP), the class will be available to all other traffic. However when needed, the entire
class is reserved solely for its owner. Moreover, you can limit the maximum bandwidth that a class can use
even if the entire bandwidth is available. Configure the following fields:
Tx Bandwidth
This parameter limits the gateway's bandwidth transmission rate. The purpose is to limit the bandwidth of the WAN
device to that of the weakest outbound link, for instance, the DSL speed provided by the ISP. This forces the router
to be the network bottleneck, where sophisticated QoS prioritization can be performed. If the device's bandwidth is
not limited correctly, the bottleneck will be in an unknown router or modem on the network path, rendering this
router’s QoS useless.
