Description
It is reserved for the group index in the form of ratio of
reserved bandwidth to upstream speed and reserved
bandwidth to downstream speed.
Check this and set the limited bandwidth ratio on the right
field. This is a protection of TCP application traffic since UDP
application traffic such as streaming video will exhaust lots of
bandwidth.
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.
The ratio typed here is reserved for limited bandwidth of UDP
application.
