Hello, thanks for your answer, This is what I thought.. Its probably a mistake in my script to measure signaling. I will check that. I have already read the document that you give to me. This document discribes most of the features of Batman and some interesting stuffs. But I am looking for

Hi, This document discribes most of the features of Batman and some interesting stuffs. But I am looking for information about global architecture, how the protocol handles threads. An example of usefull draw : http://imgur.com/3ecCY. Its not always easy to study or understand a complex

Hey again, That's pretty interesting! I don't know if we have something like an architecture illustration (but haven't see any recently). If you get anything interesting out of that (illustration, performance insights, etc), please tell us. I am trying to draw some illustration like the

[B.A.T.M.A.N.] [PATCH] batman-adv: check incoming packet type for bla

If the gateway functionality is used, some broadcast packets (DHCP requests) may be transmitted as unicast packets. As the bridge loop avoidance code now only considers the payload Ethernet destination, it may drop the DHCP request for clients which are claimed by other backbone gateways, because

Hey Guido, thanks again for the good debugging, that really helped to understand the problem :) I've sent a patch, is it possible for you to apply it and retry? it should be enough to update the two gateway nodes. Cheers Simon signature.asc Description: Digital signature

Hi Antonio I encountered the tt loop in kvm this evening, so I captured some tiny logs for you. The topology is a small chain: n1 - n2 - n3 - n4 The nodes run clean batman-adv from master (5deb69f60f388055982a1da6dce876049f86841d) with no catwoman or whatever compiled in :) -- Kind Regards
