You didn`t written system on which you want collect data.
On linux you probably can use iptables which provide counters about packets/bytes 
matched by rule.
By ipac-ng software is possible to generate statistics per IP but I don`t know if 
per port too.

btw. port 21 in FTP is used for control connection, data connections are created
on demand on dynamic ports. kernel module ip_conntrack_ftp could help.
