The way packet handling works in Linux makes it hard if not impossible
to determine what specific application created a packet. You can however
do some pretty sophisticated scheduling based on service types. This is
not a trivial topic, but if you're willing to learn a bit, this will
really help you to get started:

Mostly, you should read chapters 1-3 and 9. You'll also want to get at
least into the iptables basics. The most important stuff is already
handled in the HOWTO, but there are some interesting possibilities (rate
limiting etc.).
