Small packets and control pachets should have priority because they
carry intrractive traffic.

Large packets are for upload or download. They can wait until people
open their html pages. Some p2p applications are ill-behaved and they
send large control packets for carrying payloads.

Port 20 = ftp-data is the data channel in ftp transactions. We have file
transfer in that channel.

Port 21 - ftp is the ftp control channel. when you stop a transfer or
acknoledge something you need the program to respond at your action very
quick.

Port 22 - ssh: when you remotely manage a computer, and if you press a
key on your keyboard, the letter must appear almost when you press the key.

Port 53 - domain: when someone is browsing the Internet and waits for a
page to load, the Internet must translate quick the site address in the
IP address, so the user waits less for the page to start to load.

Port 80 - http: this is from where the pages come and the requests for
them go. The system must respond quickly (we have fast computers these
days, don't we?)

( I don't know this port and i am too lazy to open /etc/services)

Where are https, irc, messengers... ?
