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.
