Jason also explained the TWAMP + latency solution, which is an active
solution and doesn't rely on operator or automatic bandwidth providing
information, but network automatically measures latency and encodes
this information in ISIS, allowing automatic traffic engineering for
LSP to choose the lowest latency path.
I believe Jason's proposal is exactly what OP is looking for.
