The rate of outbound/inbound must be smaller than the real bandwidth to
ensure correct calculation of QoS. It is suggested to set the bandwidth value
for inbound/outbound as 80% - 85% of physical network speed provided by
ISP to maximize the QoS performance.

Description
Set the limited bandwidth ratio. This is a protection of TCP
application traffic since UDP application traffic such as
streaming video will exhaust lots of bandwidth.
Limited_bandwidth Ratio - The ratio typed here is reserved
for limited bandwidth of UDP application.
The difference in bandwidth between download and upload
are great in ADSL2+ environment. For the download speed
might be impacted by the uploading TCP ACK, you can check
this box to push ACK of upload faster to speed the network
traffic.
