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.

Hurricane Season Approaches

It is US National Hurricane Preparedness Week! Are you prepared for this year’s hurricane season? Are you ready to assist others by providing high-speed communications when the commercial facilities are not available?

As a 2019 Call for Code Program Supporter, the AREDN team asks you to watch how Call for Code 2018 winner Project Owl piloted their mesh network solution to help communities in Puerto Rico https://ibm.co/2UUv1Ge 

We plan to host a discussion on deploying an AREDN mesh network in Puerto Rico during Hamvention in our booth #1001. Please join us and contribute your ideas.

There is another way to help in creating a cleaner, safer and healthier environment for the worst hit communities and a chance to win $200,000 USD. Enter the 2019 Call for Code challenge https://ibm.co/2DINsrC


AREDN Supports Call for Code 2019

Do you want to help improve disaster communications?
Do you want to use your AREDN network as a foundation for solutions to improve disaster relief efforts?
Do you develop computer applications and want to help improve disaster communications? AREDN asks you to make a difference with your code.  

AREDN is a 2019 Call for Code Program Supporter. Join Call for Code in building solutions to improve disaster relief efforts and a chance to win $200,000

This year's Call for Code program decided to add an emphasis on healthcare needs in the lead up to and aftermath of natural disasters. The program's Chief Technology Officer (CTO) Daniel Krook writes "Specifically, we’re calling on developers to create solutions that address the following aspects of healthcare:

  • Food and water safety
  • Medical supply distribution
  • Tracking and halting disease epidemics
  • Access to medical health records
  • Mental health
  • Serving vulnerable populations

We based our healthcare...
