Hi, Michael, As matter of fact, we are dealing with this problem right now, the smart data center transformation cost a lot of money and additional power consumptions because of those additional sensors. So, yes, we are looking for such technologies that can reduce power

Hello Guangpeng If we take the DC sensors as use case and racks are organized in trees, and you add a new rack then there will be renumbering. This is why it’s safer to use this tech at L2. For the better and the worse IoT standards happen to use the IP address as a node ID. I was there when

You read me wrong Guangpeng. I’m advocating for multiple NSA L2 addresses to reflect redundancy in the network. And a single IP address that remains even if the network changes and maps all the MAC addresses. The consequence is that the IP must not derive from MAC. Though I agree with

I’m with you Michael Though in the case of this proposal I would have one IP address per constrained Device and multiple L2NSA to account for the redundant networks. I would thus not derive the IP from l2NSA but use a table eg a SCHC rule or a 6LoWPAN context to map the IP from the MAC. I’m

Hello Pascal, My apologies for late reply (I am taking some time off). Since I last wrote, thread has progressed quite a bit. Anyways...· What attracted my attention is the  header structure in Figure 6. It is often the case that field devices are smaller 8-bit or16-bit addresses connected
