[Followups restricted to just olsr-users and babel-users.]
(1) when the network is broken, Babel is the first to collapse; (2) Babel behaves well when the network is usable;
Could you be a bit more specific with "usable"?? What does that mean regarding packetloss?
If you look at Elektra's writeup, in the first test none of the protocols achieved more than 18% success -- and that's *after* link-layer ARQ. In the second test the figure was 27%.
In the third test, everyone achieved around 75% (after ARQ), which I think is still pretty marginal, but starts becoming usable.
Perhaps Henning or Elektra can tell us what was the ETX (or, equivalently, pre-ARQ packet loss) of the productive links in those tests.
(3) Babel generates too many small packets on broken networks.
Which creates more collisions in the air I assume ;-)
Well, it's still just 30 packets/s (as measured, all nodes added up), which is well within what 802.11 is designed to handle. (See Elektra's slide number 8.)
yeah ;-) Wish I had been there..
So do I.
