> @Saverio: why is the LQ multiplier not enough?
1) First problem is that I cannot configure asymetric cost:
in the current implementation the ETX of the link is the same in both
directions (you can have a little shift because cost from A to B is
computed on A and cost from B to A is computed on B, but results
should be the same).
2) Second problem is granular costs
the ETX using multipliers will be
ETX = 1 / ( LQa * multA * LQb * multB)
when the link is perfect I can simplify in
ETX = 1 / (multA * multB)
But the is very tricky to configure ETX of 18,19,20,21,22,23 adjusting
these two multipliers values on the two routers.
Moreover a packet loss on the link will add a multiplicating factor to
my link, that most of the time will go quickly above LINK_COST_BROKEN
I would like to set ETX = 18, and then just delete the link if the
normal computation of ETX without multiplier goes above
