Function name:
IP TCP/UDP Port Classification
Function description:
In L4 QoS Configuration, you can enter one of these special network transmission events,
for example we use” Down prioritize web browsing, e-mail, FTP and news “L4 QoS
Configuration and click <Apply> button, and then click <Advance >>>
button. We can
find Special TCP/UDP port 80, 280, 443, 25, 110, 20, 21, 69, 119, 2009 have already
existed and defined for your using but it is fine that you modify this pre-defined TCP/UDP
port with other port number you prefer. In ” Down prioritize web browsing, e-mail, FTP
and news “ L4 QoS Configuration with default setting, special defined TCP/UDP port
possesses lower QoS traffic than Default class ( all other TCP/UDP ports such as port
81,82,83,84,85, etc.). Giving an example, when we transmit TCP packets with port number
80 at each of port 2 and port number 81 at port 3 to port 1 until the congestion happens.
The packets from port 3 will be dropped by port 1 because the TCP packets have port
number 80 is high priority and will have higher precedence to be sent out from port 1.
