Release Candidate - Major changes and tests
 

The Release Candidate Process

 

The Release Candidate process starts with the release of nightly build 20261012-e3528941.

Subsequent nightly builds will be released when issues are fixed during this testing process and these will replace the current release candidate. The current release candidate is 20261012-e3528941. The process will continue until a build is considered stable. That will become the 4.26.X.0 release.

Please report all bugs using the usual process on GitHub. Functional bugs are the most important, cosmetic bugs are the least. You should not expect any major changes in functionality during this process. Please make sure you are running the latest release candidate before reporting an issue and please note the exact build... Read More

Below is a link to download a new verison of Babel suitable for installing on AREDN 4.26.7.0. This new version includes a single bug fix to remove a potential maximum 4MB memory leak.

HOWEVER before you install this package please following the steps below to see if you should. In many cases this update will not effect how your node behaves or is not suitable for your device. There is no need to update a node with this fix if it is already working.

1. Does you node have only 64M of memory? If you have more memory then this fix will do nothing. Yes you're wasting 4M of memory, but you node is under no memory pressure so there will be no operational difference. If you have more than 64M of memory don't install this.
2. Is...

AREDN Release 4.26.7.0 available

 

Major Features

Updated to OpenWRT 25.12.5

OpenWRT 25.12 brings a new package manager - apk. If you are currently using side-loaded .ipk packages, these cannotbe updated when AREDN is updated as they are no longer compatible and will be removed.

Faster network changes

You can now add, remove, or update tunnels without restarting the entire network stack. It’s a lot faster and less disruptive.

AREDN Development Plans

A heads up on AREDN software development plans

AREDN®, as we’ve come to know it, is 11 years old. In that time it has come a long way, supporting a wide variety of devices, a host of radio bands, and has been deployed across the world. The UI has evolved, tunnels have been added, bandwidth and throughput have increased, and more features and services can be supported. The one constant in all this has been how AREDN® manages the network, using a protocol called Optimized Link State Routing - OLSR. Unfortunately as networks have grown, this protocol has buckled, and sometimes broken, under the strain, as OLSR was never designed for the size or variety of the networks we have. This year we added a new modern network protocol - Babel (see the ...

Release Candidate Available

Nightly build 20250723 has been designated as the Release Candidate for the next AREDN production release.   If nothing weird happens, the next production release will be around August 6th.

The recent nightly builds have been very stable.  The AREDN team encourages you to wring them out and see if you can break them :-)

Enjoy!

 

Babel bug discovered

It figures...   After several months of testing, a bug in the Babel implementation surfaced - naturally after a product release.  Somewhat randomly and rarely, after a reboot or upgrade, the Babel connection between two nodes will not operate correctly. Symptoms are lack of connectivity with Babel nodes, usually in one direction rather than both. If you're experiencing this, open up the panel on a Local or Neighborhood node. The issue is evidenced by the Babel Metric in the lower right having a value of -1.

Restarting Babel at either end of the connection should resolve it, as it appears to be a boot-up timing issue. Rebooting one of the nodes is the easiest way to do this.  But consider updating to production release 3.25.5.1 which will resolve the issue.

AREDN Nightly Build Update

• a babel nightly build.

 

• Babel-only nodes will not know about OLSR-only nodes. ...

Babel Routing

Read More

AREDN Release Candidate Available

Nightly build 20250415 has been designated the release candidate for the next production release.

In it the AREDN® team is introducing Babel as a replacement for the older OLSR routing technology.   It's been seen to improve network stability and throughput.  In this release Babel and OLSR will run side-by-side, with Babel routing used where available, and OLSR used otherwise.  Already 25% of the nodes on the network are running a Babel-enabled nightly build and we've seen and heard anecdotally of significant improvements in network stability.

Additionally this release adds PtP (point to point) and PtMP (point to multipoint) RF modes to complement our existing AdHoc mode.  We’ve see notable throughput and latency improvements when using these modes, especially with 802.11ac devices. This  holds true even when mixing radios from different manufacturers.... Read More

New Experimental Radio Modes and SSID

Following on the heels of the inclusion of the Babel routing protocol to the AREDN software is another significant enhancement: nightly build 20250219 adds PtP (Point to Point) and PtMP (Point to MultiPoint) configurations. These protocols can be found in the Radio section of the AREDN UI:

 

 

Here's a brief explanation of each of them:

 

• Mesh PtMP: This makes a node act like your common access point, where Mesh Station nodes can connect to it, but not to each other, and the Mesh PtMP can only connect to Station nodes.

Introducing a New Network Protocol

The AREDN team is introducing a new networking technology into the nightly builds with the ultimate long term goal of replacing OLSR.

OLSR has many faults which AREDN has lived with for a long time. For the last couple of years we’ve been looking at alternatives and making incremental steps in the codebase to allow us to introduce something new. We can finally do that by adding Babel (https://www.irif.fr/~jch/software/babel/) to AREDN.

Babel has a number of qualities which make it good for AREDN. First, it’s a loop free protocol so, regardless of how the network is changing, routing loops will never form in the network. Second, it’s primarily a reactive protocol which sends changes to neighbors when needed rather than broadcasting its state continually. Third, the protocol understands the...

Nightly Build Firewall Behavior Change

This may only affect a few users, but the dev team thought we should put the word out so no one was surprised.

The nightly build that will be released as 20250129 changes a firewall behavior.

As it is now by default, if your node (usually a hap of some sort) didn't have a WAN connection, it would go out over the mesh to find an Internet link.   It was difficult to make sure this wasn’t happening and not very obvious how to prevent it.

The change implemented in tomorrow's build is the addition of a new switch which will determine if LAN devices of your node can reach the Internet over the AREDN network.  And it will be defaulted to off which is a change from current behavior.

AREDN Production Release 3.24.10.0 is now available.

 

The biggest change in this release if you haven't been keeping tabs on AREDN, is the "new UI". The User Interface or UI is how data is presented to a person. The old UI, written in LUA not only looked old, it was hampering the implementation of new features.  Now written in JavaScript, among other things it's more economical on bandwidth used to display the user interface.  It's also much easier to add new features. The new UI has taken 6 months and the work of many, many people. We’d like to thank everyone involved with developing, documenting, and especially debugging this; we really appreciate our community!

Because it's new, navigating around it may initially be a challenge. Steve, AB7PA, keeper of the AREDN docs, has done a stellar job in documenting the new UI. It's highly recommended you at least skim...

New User Interface in Development

Coming to an AREDN nightly build near you soon - a shiny new UI :-)
This YouTube overview by Tim KN6PLV explains why the AREDN devs decided a new UI was needed for the AREDN software.  Tim goes into the reasons why, then does a deep dive into every corner the new UI.  Folks who have seen it like it a lot.   Check it out!  https://youtu.be/KG_2ploIYzg
Steve AB7PA has provided a preview of the documentation for the new UI here: https://docs.arednmesh.org  This will eventually become available under docs.arednmesh.org after the new UI appears in the Nightly Build. ​

 

New AREDN Production Release Available

AREDN production software version 3.24.6.0 is now available, with many new features and enhancements.   Besides a fix for an RF link issue that snuck past beta testing release 3.24.4.0, this release contains these fixes and enhancements:

Enhancements

• Added MTR support via installable package (mtr-nojson).

• Improved iPerf3 service to provide data line by line rather than at the end.

• Now use the closest supernode rather than first discovered supernode.

• Made LQM+OLSRD improvements where weak connections are detected.

• Now detect "leaf" nodes and prevent them being blocked.

AREDN Release 3.23.12.0

Here are the release notes for AREDN production release 3.23.12.0, derived from nightly build 20231018

Enhancements

Added supernode support.

"Supernodes" are specially configured AREDN nodes in various locations which support a "mesh of meshes". With this release your localnode will automatically detect a nearby supernode, if one exists, and will show a new button on the Mesh Status page, labeled "Cloud Mesh". Clicking on that button will take you to the Mesh Status page of that supernode and show you all the nodes and services on the Cloud Mesh. You can navigate to any of them as though they were on your local mesh.

The URL for the supernode map is https://arednmap.xojs.org/ Clicking on any of the node types in the upper-right-hand corner of the...

Nightly Build Status 21 Sep 2023

Since the last AREDN  software production release, there have been a number of nightly builds, some of which contain significant enhancements.  As usual, the AREDN devs would appreciate some helping testing the updates.    Here's a list of the most significant ones.

• If you're planning on buying a new Mikrotik device, you'll need to install a recent nightly build on it.  Mikrotik has changed their code's compression algorithm, and the AREDN code has been modified to accommodate it and allow successful software installations.
• The Search function has been streamlined
• An installable cron package has been added for people who need more functionality than the built-in cron support
• If you've downloaded and added extra packages to a node, after updating to the latest nightly build, later builds will remember those packages and download and...

AREDN at SCALE 20x

For the last few years, AREDN has had a booth on the expo floor at SCALE, the Southern California Linux Expo.  It's happening again at the 20th annual SCALE, March 9th through 12th (https://www.socallinuxexpo.org/scale/20x), at the Pasadena Convention Center.  The Expo runs from Friday afternoon until Sunday afternoon, and the AREDN booth will be manned with knowledgeable AREDN users, including Tim KN6PLV, one of the principal AREDN developers. The booth dudes will be happy to chat about all things AREDN with you!

AREDN is derived from OpenWRT, which is a Linux "distribution". As you get into AREDN networking, it's helpful to know a bit more about Linux.  SCALE will be holding Linux training classes on both Saturday and Sunday.  After installing Linux on your computer of choice, a professional trainer from the Linux...

Release notes for AREDN nightly build 2017 and later

 

Nightly build 2017 is based on the latest OpenWRT release, version 22.03.2. (The current AREDN production release is based on OpenWRT 19.07 from January 2020). 

There are significant changes in this nightly build:

• All devices have been moved to the ath79 device tree (no more ar71xx).

• The ipq40xx device tree has been added.

• Each device now has its own image file.

• Some filenames have been changed.

 

As a result devices need to be tested carefully, at least initially.

 

The most current status on nightly builds can be found in the README file here:

AREDN production release 3.22.6.0  is now available

AREDN production release 3.22.6.0 is now available.  This is the release you've been looking for :-)

Since the last production release, there have been 136 separate ‘pull requests’ in the AREDN github repository.   Those requests pulled these significant improvements and new features into the AREDN software:
1. The conversion from Perl programming to Lua is complete - the result is a significantly smaller, somewhat faster, code base.

2. Due to the recovered space in the image, tunnels are now always installed, so nothing needs to be done with them during future upgrades.

3. After this upgrade, future upgrades should be much more reliable, especially on low memory devices.

4. Tunnels will be prevented from accidentally connecting over the mesh.

Link Quality Manager (LQM)

 

Thanks to recent developments by Tim KN6PLV, we are introducing a new tool to help manage AREDN networks.

Nightly Build 1265 contains a number of improvements broadly called Link Quality Management. It’s designed to make the AREDN network more stable and improve the available bandwidth. Tests with these changes have shown improvements from modest to close to 200% in link throughput, tested end to end with iperf3.

Documentation is here

Nightly Build Reminder

The AREDN team greatly appreciates all of the testing of the nightly builds as they roll out and introduce the new code base and features. We are paying close attention to your reports of successes and problems found.

Just as a reminder:
IMPORTANT NOTE:  While AREDN encourages you to download, install and test the nightly builds and report any issues found,  DO NOT install them in any node that doesn’t have easy access (e.g., towers, water tanks or mountain tops).  By definition nightly builds are not to be considered production grade software.

 

AREDN Development Plan 2022

Following their recent code production release, AREDN has embarked on an ambitious development plan.  Here’s a basic overview of what is on their plate

Replace Perl code with Lua

The programming language for the user interface, services and many other functions is written in Perl.   The Perl libraries are very large and AREDN has embarked upon a project to replace it with Lua, a much lighter weight programming language designed to run in embedded devices.  

In steps, the team will update the “read-only” page to Lua: 

Main, Mesh Status, etc.

Then the read-write pages will be updated: 

• Basic Setup     

• Port Forwarding DHCP and Services

Happy Mesh Year!   Yet another network test!

"PARDEN" the interruption!  October's Meshoween network test was so successful that, we've decided to celebrate with another one at the end of the year.  We'll celebrate New Nodes Eve and then Happy Mesh Year!

Seriously, this is an opportunity to stress the network again after the router storm mitigation patch has time to promulgate throughout the network.  Meshoween also revealed an issue with the performance of the Mesh Status page when the node count got high.  Both these patches were published in nightly builds in early November.  If your node's running a nightly build later than that, you should be good to go.   

The WWL - "World Wide Linkup" will start at 000Z on 1/1/2022  (afternoon of the 31st for the U.S.) and last at least 4 hours.  If you've brought up a tunnel that you don't normally use, feel free to drop it...

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...

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...

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.

ARRL Call to Action in Defense of Part 97 Allocations in the 3 and 5 GHz Bands

The FCC WT Docket 19-348 and WT Docket 19-138 will severely curtail growth of one of the newest and most effective means for Amateurs to support emergency communications.  Existing installations will be severely curtailed or, with no reasonable alternatives, be forced to cease operations.  Thousands of hams have built or are in the process of constructing high-speed data networks in the 3 & 5 GHz ham microwave allocations.

Background

AREDN (Amateur Radio Emergency Data Network) was an outgrowth of the ARRL working group on High-Speed Multimedia (HSMM).  It has evolved over the past 10-12 years from its first implementation by Broadband Hamnet (BBHN).  Over the years the AREDN Project has developed software support for nearly 70 commercial wireless routers---moving them from their Part 15 allocation into adjacent Part...

These included extending the network’s high-speed multimedia capabilities from solely 2.4 GHz to 900 MHz, 3 GHz, and 5.8 GHz, and adding 802.11n protocol to improve data throughput. The Board also acknowledged the efforts of the many AREDN implementation groups around the country who are building networks based on this technology and who stand ready to utilize them to serve the needs of their communities in times of disaster. 

​AREDN Project Announces Strategic Changes

AREDN forms a non-profit corporation to ensure continuity

The project saw the need for more formal governance and as a result, took the strategic step of organizing as a non-profit corporation.  This will help protect the user-community investments in mesh networking by setting up the framework for long-term resource management, research, and development. 

Our mission is still focused on providing the Amateur Radio Community with software, education, and support to enable them to aid public safety, emergency response and disaster relief agencies with high-speed multimedia data networks.

Continuing to rely on the financial support of a few individuals is not a sustainable means of supporting the project. Without more widespread support, the community’s growing investment in network equipment and...

New Paper on AREDN Published by TAPR

The Proceedings of the 2015 Digital Communications Conference include a paper, The AREDN Project by Andre Hansen, K6AH, which introduces AREDN, describes implementation techniques and concludes with a roadmap for the future.

Abstract

Mesh technology has been around for ten years or more. Over the past two years a team of developers has advanced the art by porting Broadband‐Hamnet’s extremely popular mesh firmware to the Ubiquiti airMAX line of commercial Wireless ISP routers and expanded its utility across a wide range of microwave bands. This has literally changed the complexion of mesh technology from an experimental, hobby‐oriented, novelty into a viable alternative network suitable for restoring some degree of Inter/intra‐net connectivity “when all else fails.”

AREDN™ - The Amateur Radio Emergency Data Network

Mesh technology has evolved over the years.  Most notably, Broadband-Hamnet™ (BBHN) has made substantial progress over the past 2 years in expanding their unique approach to environmentally robust, commercially available, Ubiquiti, hardware.  This has changed the complexion of mesh implementations from an experimental, hobby-oriented, novelty into a viable alternative network suitable for restoring some level of Inter/intra-net connectivity when “all else fails.”

Recently, the developers of BBHN software have kicked-off a new project focused on taking this technology to the next level.  Comprised of the project manager, developers, and several of the testers who brought BBHN to Ubiquiti hardware, this team is geared to pick up where BBHN left-off.

The AREDN Project mission is to provide the Amateur Radio Community with a quality solution for...
