[Babel-users] Rate limiting [was: New Version Notification...]

If you've got 10 000 nodes and 1Mbit/s links, you'll really want to
implement some filtering or aggregation.  Or perhaps add some extra
mechanisms to babeld (such as sending updates for default routes reliably).

The starting point is randomized (delayed by up to one-half the hello
interval, if memory serves), but all the packets of a full update get sent
without pause.  I could easily add some jitter between the individual
packets, if you can show me a network where it matters.

Over 802.11 in IBSS mode?  Good luck with that.

They're smart guys, they perform aggregation.

I think it should remain fairly short, without too many technical details.
