[OLSR-users] link quality / forcing hops

[Andreas Tønnesen]

Do you want statistics for OLSR control traffic or all traffic? If you 
want link statistics
then the best way is to query the driver of the interface as I do in the 
preliminary
link-layer notification code. As mentioned earlier this will brobably be 
integrated into
OLSR link-sensing later on.

If you are looking for OLSR traffic only - this could relativley easy be 
achieved with
a plugin... Creating a command-line tool to retrieve this info would not 
be too hard
either.

I could implement this - but right now I'm quite busy writing my 
thesis(on olsrd)
and I have some exams in may - so you'd have to be patient ;)

You or somebody else interested could perhaps do it? It would only be a 
matter of
keeping track of the sequence number in the OLSR header and log the loss for
the last n packages... And create a IPC interface for a application to 
fetch this info.

But I can look into it one day I can find the time.
