Module Rate Fixed Interval Rate

The fixed interval rate module emulates a connection with a limited data rate based on a packet transmission interval. It has to be combined with a queue module from which it dequeues packets at the configured interval. At each instance of the interval, a packet is dequeued from the connected queue module and sent out immediately. If the queue is empty at an instance of the interval, the transmission opportunity is wasted and the next packet can be transmitted earliest at the next instance of the interval. The module does not add a transmission delay to the packets. The module has inputs and outputs in both directions. The packet transmissions in both directions are synchronized. The interval can be configured directly or is derived from a packet rate. Both parameters are linked, so changing one of them updates the other.
