Click WAN interface number link to configure the limited bandwidth ratio for QoS of the WAN
interface.
Available settings are explained as follows:
Item Description
Enable UDP Bandwidth
Control
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.
Outbound TCP ACK
Prioritize
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.
Info
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.
