QoS
QoS can let you classify Internet application traffic by source/destination IP
address and port number. You can assign priority for each type of application and
reserve bandwidth for it. The packets of applications with higher priority will
always go first. Lower priority applications will get bandwidth after higher priority
applications get enough bandwidth. This can let you have a better experience in
using critical real time services like Internet phone, video conference ...etc. All the
applications not specified by you are classified as rule name "Others". The rule
with a smaller priority number has a higher priority; the rule with a larger priority
number has a lower priority. You can adjust the priority of the rules by moving
them up or down.
Enable/Disable QoS You can check "Enable QoS" to enable QoS functionality
for the WAN port.
Add a QoS rule into the table Click "Add" then enter a form of the QoS rule.
Click "Apply" after filling out the form the rule will be added into the table.
Remove QoS rules from the table If you want to remove QoS rules from the
table, select the QoS rules you want to remove in the table and then click "Delete
Selected". If you want remove all QoS rules from the table, just click the "Delete
All" button. Clicking "Reset" will clear your current selections.
