- Quality of Service (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 “Others”.
