Don't be unfair... Hang on, I actually said, OLSR stuff belongs on the respective mailing list there. (and suggested to take a look at BGP)
We have occasional OLSR advertisement fade-ins on this list - I guess the Babel/OLSR/Batman quarrel will become proverbial one day ;-)

Hello,
I'm currently gathering some information about available routing protocols for mesh networks for my diploma thesis. So far, I have found rather confusing things about OLSR. From
http://www.olsr.org/?q=background
I gathered that most of the optimizations to get olsr working were code improvements. However,
https://www.open-mesh.org/wiki/the-olsr-story
paints a somewhat different picture with inherent instabilities in the original concept of olsr which is why they started over with BATMAN.
Well... Let me give you my personal opinion on that. Mainly Elektra from BATMAN was very often behind a FUD strategy against OLSR. Which is weird but it is like that. Maybe it is in order to start the new project BATMAN. From the OLSR.org side, this is great that there is a new attempt at routing protocols since we can all learn from that and from the new problems that a new routing protocol will give in practice.
However, I would *not* take the-olsr-story on open-mesh.org as correct, final, authoritative nor complete. Fact is that mesh research is an ongoing process and we can all simply learn.
From what I've read on the freifunk homepage, olsr is still widely in use on freifunk networks.
it is.
I'm guessing that they are probably using the latest stable olsrd from olsr.org. However what I have not been able to find out is what protocol the current implementation from olsr.org is using. Is it still RCF-3626 compliant or does it rather contain all the optimizations from the C-Base people, thus breaking RFC compliance?
it is RFC compliant but we all turn on extensions to RFC3626 in practice (ETX, Fisheye, ...) which break compatibility. But these are flags. You can turn them off.
As part of my thesis I will have to experiment with some extensions to the OLSR protocol. In order to be able to design those, I'd like to know the protocol I'm actually using ;-)
I suggest that you start to familiarize yourself with the basic datastructures, the RFC and maybe the plugin API. You will find more help concerning these issues on olsr-dev at lists.olsr.org.
I did find the OLSRv2-Draft at
http://www.ietf.org/internet-drafts/draft-ietf-manet-olsrv2-08.txt
. This however still contains Multipoint relays, which as mentioned on open-mesh.org seem to be (have been?) one of the bigger issues -- thus my confusion.
no, ... open-mesh.org is a lot of personal opinion by Elektra. So, again... take that with a grain of salt please ;-)
There was even once a paper published by Elektra and some insitute in South Africa which again "proves" that OLSR does not scale and stuff like that.
In the history of routing protocols you can always find this trend that some proposals were made, some succeeded in acceptance (i.e. they were made an RFC) and then a *great* deal* of work was still needed to actually make it scalable and secure in practice.
Take BGP for example: we (== the internet) is still fighting with some basic security problems of BGP [1]. So even the development of BGP is still ongoing.
Summary: it is the implementation which counts! And OLSR.org put *a lot* of effort into that the last 2 years.
So the basic real dichotomy between OLSR.org and BATMAN is actually the question: "do something new or improve the old stuff?" I guess both are valid positions somehow.

The result of the FUD can be clearly seen by the uncertainty and doubt that people have been having repeatedly on this mailing list. So therefore I believe I can rest my case and the mail by Damian was the proof for my FUD theory.
I also believe that I am actually quite fair. And I really do admire the work of Axel and others! No doubt about that!
:)
ps. it would be better to join to the wireless community weekend, to work together on the olsr issues then writing such a crap!
I am currently at work and could not come. Simple as that.
Besides, I do reserve the right to have my own experience and my opinion and do not tolerate others just calling my impression crap when they have no idea of *how* often I had to "defend" against the oh- my-god-they-are-continuing-on-olsr.org-while-we-self-perceived- semigods-in-berlin-are-already-working-on-batman-which-is-bettter-and- therefore-the-rest-of-the-world-is-wrong-and-sucks attitude of some folks in Berlin. It is really tiresome to always have to "defend" a decision to still work on olsr.org in face of public *propaganda*.
I see it like that: there is room for improvement on olsr.org and there is a place for BATMAN. Different goals. That is all. But why oh why do all the people get confused when they read Elektra's text on open-mesh.org ? Why do I see the same and the same type of questions again and again? Exactly because it is propaganda.
ok, over and out. I think I made my point clear. <joke>if you want we can carry this out in person with boxing gloves</ joke> ;-))
PS: again, in case it was not clear enough - congrats to successes of BATMAN . It is *not* the issue of which is better. It is an issue if Elektra pisses on other people constantly or not. But I guess I should get simply used to that... seems like she likes it. *sigh*
whatever, a.
