Physical bandwidth restrictions
In a project, we wished to enforce a bandwidth limitation to ensure that some streams didn't go down a certain route. We simple wired-up only four of eight Ethernet wires on those paths, thus forcing the chips to negotiate a lower bandwidth connection at the hardware level. Guaranteed that the high bandwidth streams couldn't fit.
Another approach is to set TTL to be just enough for the expected route.
