Hi Ricardo, if this improves the behaviour in dense mesh scenarios, am I right in thinking we'll be looking at - from a high-level pov - changing contention window, route expiration and mcast rate dynamically on the XOs when they see the school server antenna with a strong signal, and then again when they lose sight of it. I am not familiar with the mesh driver so this may be a stupid question - is it safe to change those values on the fly? The switch-modes decision logic could be tricky - needs data from different network layers - needs tuning to avoid having ranges where we switch back-and-forth still getting to grips with how the mesh works - hopefully the above makes sense ;-) cheers, martin -- [EMAIL PROTECTED] [EMAIL PROTECTED] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
