ng_car - Commited Access Rate netgraph node type
Traffic flowing from upper to lower is considered downstream traffic. Traffic flowing from lower to upper is considered upstream traffic.
This algorithm is more polite to the TCP traffic than NG_CAR_SINGLE_RATE.
Traffic shaping is much more polite to the TCP traffic than rate limit on links with bandwidth * delay product less than 6-8 TCP segments, but it consumes additional system resources for queue processing.
