Here are some metrics on our AREDN network (real stuff - not an April Fool's joke :-)? )

2856 nodes seen on supernode network.? Of them, 63 are supernodes

Longest uptime - 810 days: VE7URC-oldPO-VE7BCE

Oldest hardware:? M0XZL-L7, M0XZL-L1: WRT54Gs (running BroadbandHamnet v3.0.? :-D

Oldest AREDN software: - GM0RAY-2:? running? 3.18.9.0 on an AirRouter HP.

Nodes running current nightly builds (Babel-enabled nodes): 631

That's (631/2856=) 22.1% - we're getting there.

Nodes running the tiny build (meaning they can't run the Babel protocol): 117
That's (117/2856=) 4.1%

Those are the models that will drop off the network at some undefined point in the future:

• AirGrid M2 XM
• AirGrid M5 XM
• AirGrid M5 XW
• AirRouter???????
• AirRouter HP??
• Bullet M2Ti?? ?
• Bullet M5?? ?
• Bullet M5Ti?? ?
• Bullet M2?? ?
• NanoBeam M2??
• NanoBridge 2
• NanoBridge 5???
• NanoStation Loco M2
• NanoStation Loco M5
• NanoStation Loco M9
• NanoStation M2 XM
• NanoStation M3 XM
• NanoStation M5 XM

Note that while these devices are old and slow, the XW versions of them have enough RAM to not have to run the tiny build.

?All the major changes planned for the next production release are in the nightly builds.? We hope to release that production build in a month or so but it would be helpful if more folks wrung out the nightly build.? Although it seems stable with no known issues, we'd like to get more eyes on it.

While the AREDN team has a few metrics to compare the Babel routing protocol performance to the OLSR performance, anecdotally we've heard that if your network has a significant percentage of Babel-enabled nodes, the performance and stability is noticeably improved.? What's your experience been?
