QoS - Quality of Service
QoS helps you to control the data upload trafc of each application from LAN (Ethernet and/
or Wireless) to WAN (Internet). It facilitates you the features to control the quality and speed of
throughput for each application when the system is running with full upstream load.
After clicking the QoS item, you can Add/Edit/Delete a QoS policy. This page will show the brief
information for policies you have added or edited. This page will also display the total available
(Non-assigned) bandwidth, in percentage, can be assigned.
Application: Assign a name that identies the new QoS application rule.
Direction: The trafc ow direction to be controlled by the QoS policy. There are two settings to be
provided in the Router:
LAN to WAN: Control the trafc ow from the local network to the outside world. For example,
when you have a FTP server inside the local network and want to have a limited trafc rate
controlled by the QoS policy, you need to add a policy with LAN to WAN direction setting.
WAN to LAN: Control Trafc ow from the WAN to LAN. (The connection maybe either issued
from LAN to WAN or WAN to LAN.)
Protocol: Select the supported protocol from the drop down list. For GRE protocol, there is no
need to specify the IP addresses or Application ports in this page. For other protocols, at least one
value shall be given.
Any: No protocol type is specied.
TCP
UDP
ICMP
GRE: For PPTP VPN Connections.
