Flow control is an essential part of ensuring that fast federates (or federates with fast connections) do not overwhelm slow receivers. The problem is this - a slow SENDER, that is OK for receiving, can get well out of sync with other federates. Although rare, I have encountered this in the TP testing federate!
My laptop's USB3 GB NIC does not have as good of a throughput when sending as it does when receiving. As such, the slow federate is able to receive quickly enough, and then grant more credits to a sender, but it isn't able to match the output pace.
Adding support for timestepped looping will bring all federates to the level of the lowest common denominator.
Acceptance Criteria
Once complete:
[ ] User will be able to specify the --timestepped argument on the command line and the Throughput test federate will go into timestepped mode, advancing time with each step.
