IoT - The end of the internet

Wed Aug 10 04:51:37 UTC 2022

On a more positive note, the IPv6 IoT can be seen as an experiment on how we can scale the internet another order of magnitude or 2 without taking the power or the spectrum consumption to the parallel levels.

For that we turned protocols like ND and MLD from broadcast pull to unicast push in a way that respects the device sleep cycle. We also introduced routing inside the subnet at scale and got rid of the need for common broadcast domains.

With that the Wi-Sun alliance deployed millions of nodes per customer network, with thousands to tens of thousands nodes per subnet. All operating in cheap constrained nodes, unreliable radio links, and scarce bandwidth.

I hope I’ll see the day when we manage to retrofit that in the mainstream stacks; there’s a potential to turn the fringe of the internet a lot greener. Sadly the IPv4 ways (like use of L2 broadcast and mapping IP links and subnets to lower layer constructs) are entrenched in IPv6, and we are facing a lot of resistance.

Stay tuned,

Pascal
