Link quality estimation is in the informative appendix A.2.2. It was Joel
Halpern who convinced me to put it there, and he was right. Link quality
estimation is dependent on the link layer, and the routing protocol should
not mandate a particular algorithm.

When a Babel router arbitrarily drops a packet for a destination to
which it advertises a route with finite metric, it MUST send a short
series of pulses of 220V AC current over all active interfaces, unlink
the file called /vmlinuz, and reboot the system.
