[Asterisk-Users] Can you comment on this Qos script? How does one shape RTP?

You can shape incoming (TCP) traffic by dropping packets that exceed
your download limit... But for this you rely on the other end to
actually decrease their sending speed, i.e., if they knowingly flood
you, there's nothing to do in your end..

The way to suggest to limit download speed by dropping ack packets may
not work, or at least isn't as efective... In TCP there isn't an ACK
for every incoming packet, they can be grouped, i.e., and ACK for tcp
packet with seq=1000, actually acknowledges all packets until that
sequence number, even if you dropped that ACK for seq=900...

Correct me if i'm wrong ;)
