Sounds like you need something which allows each flow to burst for a short time, but throttles long-lived connections. In addition, you may need to rate-limit the SYN packets from each node to thwart clients which try to open many short-lived connections in order to defeat the long-lived connection throttling. AFAIK you'll need to break out the C compiler to achieve this on Linux...
