Re: [Sipdht-devel] SIPDHT simulation

[Oredope, A. <ao...@es...>]

Thanks a lot Enrico. I do apologise for the late response, I was trying
to get someone who could help me translate Italian and lucky enough
someone in my group is willing. So, please go ahead and send the report.

Thanks and Regards,

Tola

Messages will be routed instead of redirected.  The advantage is only=20
for the client which has to send just one message (as it does with=20
regular SIP proxyes).

Default is routing.  Was the crash an "Abort" or a "Segmentation Fault"?

  In the first case, it happens because two many nodes died in one=20
stabilization interval.  You can avoid it tuning the interval length=20
(through the -s option).  In the latter case, it is a bug, worth=20
notified on sourceforge bugtracking system.

Actually a student wrote his master thesis on it and did a lot of=20
simulations; unfortunately for you it is written in Italian.  If you are

interested, I can send you (in PM) a copy of the doc; perhaps some=20
automatic translator could help you.
