Hi, Just to write you a quick report of the babelz test we made at WBM3.1416.
1. Ivo made OpenWRT (Backfire) package for Babelz, which is available here: http://xi-group.com/babelz/ We installed it successfully on 8 foneras running backfire. Please mirror before it disappears. 2. We made some tests with 4 pairs of foneras (8 routers total) connected with an ethernet cable in between, one fonera on ch1 and the other one on ch13 (radio was at 1dbm 1mbits) 3. Babelz was running with the option -z 2,30 on both wlan0 and eth0 4. We got pretty stable results by distancing the nodes, and the route was the correct one, hoping from one channel to the other, offering 0% packet loss. 5. We did not had time to test the throughput, since we had a problem of doing more then 4 hops, since the 4 node was always associating with the second one (with packet loss) 6. The last hop between node 3 and node 4 was still hoping over the same radio, because the other radio was misconfigured (the node refused to put itself on ch13 due to regulation domain I suppose) Wishes: we would like to patch the current Babelz to forbid the routing protocol to hop over the same channel. We gonna organise another WBM V3.5 in Charleroi in November (Charleroi has cheap flights with Ryanair). I am also looking for people with a bit of time to setup an OpenVZ with several containers which would export a wlanX interface from the hwsim. That would help to see how the babel daemon reacts in a simulated environnement. Another idea is to use iptables to force some routes when some nodes sees at other. But that should not normally happen of the routing daemon chooses the fastest path, not the shortest one.

Instead of explicitly seeking to sanction the patentability of software, they are now seeking to create a central European patent court, which would establish and enforce patentability rules in their favor, without any possibility of correction by competing courts or democratically elected legislators." _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
