Main OLSR-NG project blog: http://olsr.funkfeuer.at

Slides from the OLSR-NG kickoff presentation: http://outpost.funkfeuer.at/~aaron/olsr-ng.pdf

We communicate on the olsr-dev mailinglist: https://www.olsr.org/mailman/listinfo/olsr-dev


Goals

  1. Clean up the code of OLSR (http://www.olsr.org),
  2. improve the algorithms of OLSR and make it more scalable.
  3. Furthermore, produce a new RFC for a (potential) new mesh routing protocol which is based on the experiences of OLSR coding (at the moment the most promising candidate for this RFC is B.A.T.M.A.N)


OLSR-NG is a open source project. Meaning everybody is invited to join in and help. We do have some bounties for the best solutions. If you want to participate, drop us an email: mailto:aaron@lo-res.org and mailto:bernd@firmix.at

Current Status

  • olsrd 0.5 was released! Thx everybody a lot!
  • UML test server is being worked on. This will allow the B.A.T.M.A.N team to test their protocol and us to test our scalability ideas with 1000nd of olsr instances.
  • Ongoing code cleanups
  • AVL tree optimizations

UML test server

center|500px|topo map of first UML instances running in parallel. All instances are connected via one single uml_switch (virtual HW switch)

Who is working on what?

Who What Status
Bernd , Thomas Lopatic, Hannes release 0.5 DONE
Hannes Gredler tcpdump parses olsr packets, DONE
Aaron,Bernd olsr-ng test server WIP
Aaron theory, complexity analysis. Goal: find the best complexity on the algorithmic side. The basic ideas seem like 90% finished. Will be presented at the TU lecture "Verteilte Systeme" ("Distributed Systems"), 20.4.2007
Zethix, Aaron UML cluster setup WIP, currently we can start around 500+ UML instances. http://www.openvz.org seems also like a promising solution

contact mailto:aaron@lo-res.org or Bernd if you are interested in participating!

Next Steps

  • TU Wien lecture "Verteilte systeme", 20.4.2007 will present our ideas about optimizing complexity. Aaron also wants to adress more students from the TU to participate
  • finalize the UML test server
  • try out the optimization ideas and document the speedup

  AdHocSys is a two-year European project to provide reliable broadband services in rural and mountain regions. This objective
  will be achieved by means of the creation of a wireless ad hoc broadband network, with special enhancements to reliability
  and availability. The network consists of one or several gateways connecting to the global Internet and several intermediate
  nodes which provide multihop connections between the gateways and end users.
