Hi Kerry and Alexander,

Thank you very much for the information. It seems the existing standards serve their purpose well. But Kerry did mention an interesting point: both these networks have low data rate and are insensitive to latency. So maybe for the networks or applications where low latency is a critical requirement in addition to the bandwidth efficiency, we could find such context-less scheme more compelling. This is very helpful discussion. Thanks a lot!

Best regards,
Haoyu

Hi Alexander,

Thanks for the clarification! It seems you suggest that the bandwidth efficiency (i.e., the header overhead) is much more important than the cost of storage and processing in wireless. It would be great if we could find some quantitative research results. Is there any such info available?  It’s also good to know that SCHC already supports direct device communications.  How about 6loWPAN? Same?

It is important to note that there are several 6lo data links that employ RFC6282
header compression including RFC8163, which is wired. (Indeed, I believe 6282
is a common denominator of published 6lo RFCs.) So, from my perspective, I'd
like your proposal to show why RFC6282 _won't_ work for your application.

Re: quantitative research results for the comparative energy costs of different
6lo design tradeoffs, I believe these studies do exist and folks in t2trg might be
able to point you to specific papers. Most (all?) 6lo data links are characterized
by low data rates, so it's important to consider the latency win of IPv6 header
compression as an additional consideration.

Regards, Kerry
