Meshchat Usage Poll
We are considering how the future version of AREDN mesh network software might affect the use of the Meshchat application.
Please help us by responding to the Meshchat poll here.

Report on Meshoween 2021 network test
Note - this report is written from a Southern California perspective. Depending on your location, as they say YMMV!
During the test the node count on the linked networks locally rose to around 1,090. N2MH's N2MH-Hub saw 1428, most likely a record for an AREDN network.
Observations:
As we hoped, network storms never appeared from our West Coast point of view, and none have been reported to date. Network traffic was not substantially higher than normal. Using KN6PLV's Mesh Monitor, messages per second were averaging about 600 before the test. During the test it hovered closer to 700. Most of the increase in traffic was due to OLSR routing broadcasts, which each node has to handle.
As we expected, older devices struggled. Many wound up with a load significantly greater than 1 (which is a full load for a single-CPU device like these), indicating their CPUs were struggling to keep up with their pending processes. Ssh'ing into a few of them and running top showed that with node counts around 1,000, loads of around 4-5 were seen.
Things we didn't expect:
While the slower nodes struggled with displaying UI pages, they were usually still able to pass traffic. But occasionally that older hardware bogged down so much that it couldn't. Perhaps some effort should be made to prioritize traffic handling...

Meshoween test results
We've wrapped up the Meshoween network abuse test :-).
If you participated and have any specific observations, please pass them along to me (orv.beach@gmail.com) and they'll be rolled them into the report on the test.
tl;dr - it went pretty well - a few surprises.

Network Test Saturday, October 30th
As an AREDN network grows in size and/or complexity, it will eventually encounter a packet storm that would pretty much cripple its traffic-carrying capabilities until the storm fades out, which could be hours. (The writers of the OLSR mobile routing protocol probably never envisioned it having to handle networks of the size amateurs are creating.) This is significantly limiting the growth and performance of our networks.
Recently released nightly build 571 provides a substantial amount of resistance to these storms. As a test of the network's robustness (or not) Saturday October 30th at 9 a.m. local we'll attempt to link as many AREDN networks together as possible.
We did a 'test test' earlier in the week on the West Coast when the Southern California and Bay area networks were linked. Node counts got up to a bit over 800 and few reports were received, so we're ready for Saturday!
Test preparation
Prior to Saturday's test, it's recommended that in order to protect your node(s) that you upgrade them to the latest nightly build (599 as of this writing). This is especially important on nodes that pass data through (as opposed to being an end-point on a network).
Also prior to Saturday, establish some baseline performance measurements on your network. Suggestions are:
- Quality of VOIP phone calls
- iperf throughput...

AREDN endorses Battlemesh v12
AREDN supports this year’s “Wireless Battle of the Mesh – Building Community Networks for Fun and Non-Profit”.
AREDN software uses OLSRv1 protocol for managing IP routing. The AREDN development team closely watches the improvements made by participants in the Battlemesh events. We plan to use these enhancements in future AREDN releases as the mobile adhoc mesh routing protocols evolve.
This year’s Battlemesh event will take place in Saint-Denis (Paris), France from Monday to Sunday, July 8 through July 14, 2019. The location is at a 5 to10 minute walk from the Saint-Denis railway station on the Train H (faster) or RER D, both easily accessible from the center of Paris. Make sure to buy a ticket for zone 3. The street address is Le 6B, 6-10 quai de Seine, 93200 Saint-Denis, France.
The event itself is free of charge and open for all!
Battlemesh brings people together from around the globe who are interested in wireless mesh networks, community networks and DIY Internet access providers. The organizers envision 7 days full...
