Finally i installed rv772 on 14 nodes real-world, rural nicaragua "non-profit-WISP/community network" parallel to existing olsrd(0.4.10/0.5.2/0.5.4pre)/ batmand_0.2-rv502.=20 the solar powered nodes run bmxd-rv772 for almost 36hrs now, with no significant instabilities(with lots of tunneled download-traffic, the tunnel get's a bit unstable, what Axel already=20 fixed in rv774). CPU-usage on client nodes looks less than in batmand_0.2, and slightly more than olsrd (would be interesting to see that scaling in a cloud with >100 nodes (how's the=20 "massive parallel vm simulation" going btw?)), but is significantly higher (about factor 2) on gateway node. Best path-detection and usability/stability of routes so far. All nodes seem visible everywhere anytime, which is the case in olsrd as well, but not in batmand_0.2. I'm located two hops from the GW where my server also is. So i'm streaming music from there to check the stability of the route: with only olsrd it gets silent (with 1024KB disk cache in mplayer, ~40sec) pretty regularly (because of "collapsing=20 routing tables" somewhere), with only batmand_0.2 it's even worse (because the GW node "doesn't hear my OGMs" too well). Both together are pretty usable. So i tried with only bmxd and disk cache set to 32KB (>1.5sec) and in tree hours music stopped once for <2sec ! =66rom the "user-feeling" it's the way best mesh-daemon i tried so far. for fairness i have to say that my olsrds are neither all up to date, nor pretty well configured, but i beleave olsrd is a=20 "historically crippled design" and the evolution of batmand will show the possibilities of wireless mesh networking.=20 this all needs some further testing and improvements, but i'm pretty sure all the good bits will find their way into 0.3-final. Thanks to Elektra, Marek, Axel and everyone else who put so much energy into this amazing peace of free software.
