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.
