3.3.26 Qos(Quality of Service)
The 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. You can adjust the priority of the rules by moving them up 
or down. 
Note: If the total assigned bandwidth of higher priority applications is larger than the maximum bandwidth 
provided by the WAN port, the other applications will not get any bandwidth.
