  3. Javier Cardona Goals 1. To facilitate the adoption of the upcoming standard of 802.11s by providing its first open implementation. 2. To replace the numerous existing, non-interoperable, incomplete mesh implementations with one based on the standard. 3. To raise visibility of 802.11s technology and to promote a community of active developers interested in 802.11s.

  6. Javier Cardona Platform (Software)‏ • open80211s will run on Linux. • based on the generic 802.11 networking stack (mac80211)‏ • aim to merge upstream (Linus tree)‏ • once accepted, forever maintained • vendor independence • good quality code!

  7. Javier Cardona Platform (Hardware)‏ • “softmac” wireless network cards. • Open Linux driver available, no binary modules. • Specific hardware will depend on project sponsors.

  8. Javier Cardona Planned Features Frame format 7 Mesh discovery and PLM 10.3, 11A.1 Mesh path selection 11A.3, 5-8 HWMP, OLSR 11A.6, 11A.7 Forwarding 11A.3.4 MDA 9.21 Mesh beaconing and sync 11A.10 Mesh interworking 11A.3 Security 8.8, 11A.2 Power Management 11A.11 Congestion control 11A.9

  9. Javier Cardona Licensing • General Public License (GPL)‏ • No risk for vendors (won't compete with proprietary implementations)‏ • No risk for good hearted developers (contributions will not be “hijacked”)‏ • ... and no choice if it is to be accepted in the Linux kernel

  10. Javier Cardona Testing • Build test infrastructure first, code later. • Apply lessons learned from OLPC...

  11. Javier Cardona Testing Lesson #1 • Node density is a good thing

  12. Javier Cardona Testing Lesson #2 • Blinding Table is a must

  13. Javier Cardona Testing Lesson #2 • Blinding Table is a must

  14. Testing Lesson #3 • Give all developers remote access to testbed Javier Cardona

  15. Testing Lesson #3 • Give all developers remote access to testbed Javier Cardona

  16. Testing Lesson #3 • Give all developers remote access to testbed ORBIT, Open-Access Research Testbed for Next-Generation Wireless Networks Javier Cardona

  17. Testing Lesson #4 • Keep Lazy-WDS APs far, far away... Javier Cardona

  18. Testing Lesson #5 • Mesh is cool. Let people contribute. Javier Cardona

  19. Javier Cardona Funding • Funded by sponsors, as many other open source projects. • Looking for sponsor abundance and diversity • good for vendor-neutrality • leverage different areas of expertise • Talk to me if you want to know more.

  20. Javier Cardona • Thank you!
