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...

Meshoween is in a week!

Folks, next Saturday is Meshoween, where nasty packet storms strike terror into the most experienced ham network user :-)

Seriously, we'll be linking up big and small networks to see how our ham radio networks handle huge routing table broadcasts.

If you haven't yet updated your node(s) to nightly build 571 (or later), please seriously consider doing so.  It will  help your node fight off any scary packet storms!

Monitoring instructions will be promulgated a day or two prior to Meshoween.

It's Linktober!  "Meshoween" is coming :-)


We've found that as networks grow both in node count and complexity, it's almost inevitable that they'll suffer from a packet storm (or storms) eventually.

Now that the patch for mitigating those network packet storms has been rolled into an AREDN nightly build, we've decided that it's time to stress-test our network.  On October 30th (starting at say, 9 a.m. local time) we'll attempt to link as many networks together to see how the network behaves.  If you have a long-haul tunnel that you can bring up, feel free to do so.

HOWEVER, if you decide to participate in the test, or think you might be on a network that gets linked in, it's highly recommended that you update your node(s) to nightly build 571 or later to "inoculate" them against a possible incoming network storm.

Before October 30th, we'll provide a reminder and instructions on what to monitor during the test.
Thanks in advance for your consideration!  Please pass this along to your AREDN network neighbors.

AREDN Conference 


The AREDN team decided to revisit the idea of an AREDN Conference in the Spring of 2022. There are currently a lot of tasks in progress with few of them far along enough to be interesting topics for a presentation.
Continue to watch the AREDNmesh.org website for updates.

AREDN Presentations at SCALE 17X March 10, 2019

There will be two AREDN presentations at the 17th Annual Southern California Linux Expo – SCALE 17X – to be held on March 7-10, 2019 at the Pasadena Convention Center in Pasadena, California, near Los Angeles.

Both presentations will be on Sunday afternoon, March 10 in room 212.

The first talk by Orv Beach, W6BI is titled “The Ham Radio Internet - a Progress Report”. It will start at 15:00 in Room 212.

Orv reports that IP Networking is one of the fastest growing modes in amateur radio.  The ham radio internet (lower-case eye) continues to grow in both capabilities and span. Driven by improvements in custom open source software for wireless access points by AREDN (arednmesh.org) and with their support of more equipment from more vendors, it now covers from Santa Barbara to the Mexican border and east at least to the Inland Empire.  At any given time, there are more than 300 nodes up and running.

He will detail that growth with emphasis on Southern California, with metrics, maps and graphs.  He'll also cover some of the more significant network events, including...

Yuma Hamfest 2019


Andre, K6AH, will present an update on the AREDN team's open source software development progress and report on useful tools and techniques to ensure a successful mesh network implementation.  His talk "AREDN Project: New developments in software and successful implementations around the Southwestern Division " will be given on Saturday, February 16, 2019 at 11:40 am. Andre will describe new Emcom applications which make the mesh even more usable.

The Yuma Hamfest and ARRL Southwestern Division Convention will be held on Friday and Saturday, February 15 & 16, 2019 at the Yuma County Fairgrounds, 2520 E. 32nd Street, Yuma, AZ 85365. For more information, see the Yuma Hamfest website. For tickets and vendor registrations, see their online registration form.
