"ng_dummy" is a simple traffic shaper node that implements control of traffic flow in both upstream and downstream direction. In each direction, the traffic flows through the sequence of two FIFO-type queues, which implement different queuing policies. The "inbound" queue is rate limited, and emulates an interface output buffer. On "outbound" queue, frames are dequeued based on preconfigured delay, thus emulating propagation effects on a transmission link. Additional features include random frame discarding based on BER; and emulation of phantom traffic, which competes for available bandwidth, and thereby introduces inbound queue congestions and delay jitter.
