HFSC General Information
If you put ack packets in a high bw queue, they will confirm with the remote system that data was received.
You can give certain services priority and keep speed and latency low.
You can serve x amount of data out quickly while slowing long term objects. You decide you want to serve out data quickly in the beginning of the connection and slow down after a few seconds. This is called a nonlinear service curve (NLSC or just SC).[1]
