There was a 3.0 PDLM release on 11/1/05 for Bittorrent traffic.

saturating the network with residential users using bittorrent/edonkey et al, while suffocating business customers. Here goes. Netfilter/IpTables (and a slew of commercial
products I'm
sure) has a Layer 7 traffic classifier, meaning it
can
identify specific file transfer applications and set
a
DiffServ bit. This means it can tell between a real
http
request and a edonkey transfer, even if they are
both using
http. It also has rate-limiting capability. So...
If you
pass all of the traffic destined for your DSL
customers
through an iptables box (single point of failure)
then you
can classify and rate-limit the downstream rate on a
per-application basis. Fwiw, if you are using diffserv bits, you could push
the
rate-limits down to the router with a qos policy in
it
instead of doing it all in the iptables box. References on this.. The netfilter website (for classification info) and the Linux advanced router
tools
