The allegations are devoid of any scientific back-up and look like searching for attention.

Hi Jordi, all, I guess you are referring to the study that was echoed in RFC7849: == According to [Power], the consumption of a cellular device with a keep-alive interval equal to 20 seconds (which is the default value in [RFC3948], for example) is 29 mA (2G) / 34 mA (3G). This consumption is reduced to 16 mA (2G) / 24 mA (3G) when the interval is increased to 40 seconds, to 9.1 mA (2G) / 16 mA (3G) if the interval is equal to 150 seconds, and to 7.3 mA (2G) / 14 mA (3G) if the interval is equal to 180 seconds. When no keep-alive is issued, the consumption would be 5.2 mA (2G) / 6.1 mA (3G). The impact of keepalive messages would be more severe if multiple applications are issuing those messages (e.g., SIP, IPsec, etc.). == That’s said, and as usual, we need to be careful in extrapolating results.

That was especially relevant in cellular phones, but if you add the thousands of millions of NAT boxes ...

Regardless of that, it's far from clear that even if those results were valid in 2017 that they are still valid today, and how they relate to total power consumption, because for all I know base stations use 10% less power for IPv6 and core routers use 12.5% less. Warren, shall I write a draft raising those hypotheses? How much power is being wasted at this moment by domestic NATs and CGN boxes?
