[OLSR-users] willingness vs. LQ routing

[Should we have a "LinkQualityMult" per-interface configuration directive?]

Okay, that sounds convincing. It'll be in 0.4.9, then. :-) Or am I 
missing something? Any objections anyone?

I am afraid that this is currently no as easy to implement. Dynamic 
reconfiguration is currently not supported by olsrd. This will probably 
be part of the new GUI infrastructure that we plan for one of the 
upcoming releases. The idea is to use the GUI to change configuration 
parameters and push them into a running olsrd process. Then dynamically 
updating the multiplier would be trivial.

Well, once a node emits a TC message, the idea is that the whole network 
learns the new state of affairs at this node within a pretty short time. 
So, I do not expect any problems, if you stay in the realm of seconds 
and not milliseconds.
