A long, long time ago, I suggested a Path BW Discovery mechanism
to the IETF, analogous to the Path MTU Discovery mechanism, but
it didn't get any traction.  Such information could be extremely
useful to TCP endpoints, to determine a maximum window size to
use, to effectively rate limit a much stronger sender from
overpowering a much weaker receiver (for example 10-GigE -> GigE),
resulting in abominable performance across large RTT paths
(as low as 12 Mbps), even in the absence of any real network
contention.
