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, and then click
Custom L4. 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.
