While the mechanism is slightly different, this sounds like Explicit
Transport Error Notification (ETEN) done again. See:
Rajesh Krishnan, James P.G. Sterbenz, Wesley M. Eddy, Craig Partridge
and Mark Allman, "Explicit transport error notification (ETEN) for
error-prone wireless and satellite networks," Computer Networks,
46(3), October 2004, pp. 343-362.
I'll note that my co-authors and I continue to debate exactly how much
benefit such a service provides. My reaction, from the "Oracle ETEN"
simulations in the paper (where we report the maximum improvement possible
if you know perfectly and immediately which packets are lost) is that
the gains are not enough to merit implementing the service.
Your mileage may vary!
