and my tests with 0.3-beta_~rv720 showed path-detection pretty
broken, i tried exp-0.3. 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.
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
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
"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
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 !
from 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
"historically crippled design" and the evolution of batmand will
show the possibilities of wireless mesh networking.
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.
