[B.A.T.M.A.N.] Distributing Data using BATMAN-Multicast

[Shantanoo Desai]

Hello all,


I have developed a Multicast based Data Distribution protocol and would 
like to compare it with Batman's Multicast feature. I know how to enable 
the multicast on the the mesh interface but is there any tool or utility 
I can use to send data over the Mesh network ? scp of sftp won't work 
since there is no multicast or broadcasting present in them.

I would like to compare how quick can data be disseminated in a Batman 
enabled Mesh network versus the protocol that I have developed over an 
adhoc network consisting of multiple Raspberry Pis.


Any hints would be suggested.


Thanks,


Shan

iperf can generate multicast traffic.

Cool :-)! I would love to do the same, or at least have a look at
the protocol algorithm you have developed. Is there any additional
information about it available online somewhere?

Does that protocol distribute the data to all nodes or just the
ones interested in it?

You've already lost me here. You say that your protocol is a "data
distribution protocol" which is using multicast ("Multicast based"). But the
L2 multicast feature [1] of batman-adv is an optimization which tried to
reduce the amount of broadcasts on the underlying layer (for example wifi)
while still allow interested multicast listeners to receive the data. So you
could say that it "implements" L2 multicast in a slightly different way than
in older batman-adv versions (which was just using broadcasts on the
underlying layer).

So your description sounds to me like these things are two different things
for two different tasks. Basically two different layers in the stack. Can you
clarify this?

Kind regards,
	Sven
