3. doc.: IEEE 802.11-07/2164r1 Submission July 2007 Javier CardonaSlide 3 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. doc.: IEEE 802.11-07/2164r1 Submission July 2007 Javier CardonaSlide 6 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. doc.: IEEE 802.11-07/2164r1 Submission July 2007 Javier CardonaSlide 7 Platform (Hardware)‏ “softmac” wireless network cards. Open Linux driver available, no binary modules. Specific hardware will depend on project sponsors.
