Dear all, It's been over five months in the making, but I'm happy to announce that babeld-1.4.0 is available from
http://www.pps.univ-paris-diderot.fr/~jch/software/files/babeld-1.4.0.tar.gz http://www.pps.univ-paris-diderot.fr/~jch/software/files/babeld-1.4.0.tar.gz.asc For more information about the Babel routing protocol, please see http://www.pps.univ-paris-diderot.fr/~jch/software/babel/ The main news in version 1.4.0 is an all new hysteresis algorithm, that slows convergence a little bit but dramatically reduces the amount of route flapping. In redundant networks, the new algorithm does not cause any noticeable slowdown; in poor networks, it might cause up to 4 seconds delay in switching to a new route when the old route is lost. While this algorithm has received a fair amount of testing, I'm still very much interested in any success or failure reports. You can disable the hysteresis algorithm by passing the flag "-M0" to babeld on the command line. Other news include some changes to the local interface, which is now more easily parsed by scripts and accepts multiple simultaneous connections, as well as some code to detect BATMAN interfaces and treat them as wireless. There's also a new flag "-r" that might be interesting if you have no persistent storage on your nodes. Thanks to all that helped develop this version, and especially the poor testers who had to bear with my ranting as I struggled with explaining the hysteresis algorithm to myself. -- Juliusz 3 May 2013: babeld-1.4.0 * Change the route selection algorithm to used a smoothed metric in addition to the "real" metric. This reduces the amount of route flapping without any special case hacks. * New flag -r, use a random router-id. This avoids temporarily unreachable nodes after a reboot when persistent storage is not available. * INCOMPATIBLE CHANGE: the local interface now announces the local hostname, and marks the end of the initial route dump. (Thanks to Gabriel Kerneis.) * The local interface is now able to accept multiple simultaneous connections. * Detect BATMAN interfaces, don't assume they are wired.
