No, not directly to hosts. You do however can setup some IP SLA
measurements to measure if you have congestion on your network the
router will know and can act on it.
Another way more extensive option would be to implement OER/PfR as
this is based on several measurements as well to see if the network is
congested and can act on it and select different exit points in the
network not only based on bandwidth.
But I don't have a simple answer to your question as the only
congestion notification I'm aware of that you can send to hosts is
through TCP ECN.

Hello,
Does anyone know if there is a method other than ECN to send
congestion notification to hosts?
Thanks,
