QoS - Quality of Service

QoS helps you to control the data upload traffic 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 identifies the new QoS application rule.

Direction: The traffic flow direction to be controlled by the QoS policy. There are two settings to be

provided in the Router:

LAN to WAN: Control the traffic flow 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 traffic rate

controlled by the QoS policy, you need to add a policy with LAN to WAN direction setting.

WAN to LAN: Control Traffic flow 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 specified.

TCP

UDP

ICMP

GRE: For PPTP VPN Connections.
