Dear Urs,

Let me keep the list on to reply to some questions, as you are not the
first to ask:

* Most routers we are interested in have multiple power supply. Our
strategy is to use one measurement unit per PSU. That demands extra
hardware, but we wouldn't want to have two PSU connected to the same
power meter anyway as this would create a potential single point of
failure.
* Network connectivity for the Pi is required but DOES WORK BEHIND A
FIREWALL. The only requirement is that the Pi must be able to connect
to the Internet.

Thanks again to those who already reached out!




"the Internet" - you mean Port 443, any IP?

Actually, no. We use a custom port to establish an gRPC connection from 
the Pi to our server back at ETH. So, if your network has tight security 
rules, the only thing we really need in one open port open towards one 
IP address.


Best,

Hi Romain,

I just looked at the power data our PDUs show (Riedo uPDU, Swiss 
product) and didn't find any correlation (<1%) to the bandwith consumed. 
So I guess, the consumption is mostly dependent to the equipment 
installed and not by the bandwidth consumed.


Regards,

Claudius

Dear all,

My name is Romain; I’m a researcher at ETH Zürich working with Laurent 
Vanbever. I have led projects on sustainable networking for about 2+ 
years now.


One important challenge the academic community currently faces is the 
lack of quality data for the energy a router or switch consumes. To 
address this, we work on fine-grained power modeling of network devices, 
and we need data to validate their accuracy “in the wild.” To facilitate 
that, we worked to realize the vision of “RIPE Atlas for power data” I 
pitched at last winter’s RIPE meeting 
. And I’m happy to say 
that we are ready to start distributing measurement units!


Concretely, we are looking for people willing to

  *

Install measurement units in series of each PSU of routers and
switches. The measurement unit is an MCP39F511N
 power
meter combined with a Raspberry Pi for management and data collection:

We will provide the appropriate cabling. To control the unit, the Pi
needs to be connected to a publicly reachable network via RJ45 (WiFi
connectivity is technically possible as well, but requires
additional setup)

  *

Share device-specific data with us, including at minima

  o Packet and/or byte counters for the active device interfaces.
  o Types and numbers of transceivers plugged in.

and optionally

  o PSU-internal measurements
  o Operating system version
  o Fan speeds
  o CPU load
  o Average room temperature conditions
  *

Let the measurement run for at least one week.

  *

Send us back the measurement units (we provide pre-labeled packaging
for that).

In return, we can only offer our sincere gratitude and the guarantee 
that your effort will contribute to the progress of science! I know it s 
not much, but I hope that’s worth something :-)


➡️ If you are interested, please let me know by replying to this email. 
Thank you in advance!


Note: We want to publish the collected data (in an anonymized way), but 
that is *optional*. If you are willing to contribute but your 
organization opposes the data sharing, we won’t publish it, and we will 
sign NDAs if necessary.


Thank you again for reading! Looking forward to hearing from you,
