Re: [Sipdht-devel] SIPDHT simulation

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

Thanks for you quick response.

Concerning the -R option, I will give it a try, but what are the
advantages?=20
Is the default SIPDHT configuration set to routing or redirecting? If
redirecting, then this is may explain the system crash we experience
when we kill multiple nodes (instances) at the same time. We were
thinking may be the crash is due to running a lot of instances on a
single node. Is this right?

Also, thanks for the link, it was quite helpful. Concerning the
algorithm, we will try to work with it and let the mailing list know our
progress.=20

Were there any simulations for SIPDHT before the actual implementation?
If yes, are there any materials (papers, journal or reports) on the
results. Any advise on the best way to simulate Chord?

I apologise for the long list of questions

Regards,

Tola

It is surely interesting; I'd suggest to try the -R option for making
nodes act as routing proxies (instead of redirecting).

With such tools you can do simulations in the strict sense of the term
(i.e. opposed to emulations, testbeds);  they are definitely worth
doing, but it is not clear to me how they relate to sipdht.  Or are you
planning to simulate the implemented algorithm
(http://sipdht.sf.net/algo.html)?
