Hi, IANA has been asked to notify the 6lo group and the authors of RFC 8025 as well as the IESG-designated experts that the authors of draft-irtf-icnrg-icnlowpan-10 (and the RG) have accepted a proposed change to an assignment in that document.
Carles and Shwetha, can you confirm that we can move forward with this registry update? The issue is that Table 2 in https://datatracker.ietf.org/doc/html/draft-irtf-icnrg-icnlowpan is currently instructing IANA to make this registration in the Dispatch Type Field registry (we understand that this "TBD1" should be page 14): 11 1xxxxx | TBD1 | Compressed CCNx Content Object messages However, 11 11xxxx has already been assigned to "Page switch" for pages 0-15: https://www.iana.org/assignments/_6lowpan-parameters This is the solution suggested by the experts and accepted by the authors: ===== One simple solution could be as follows: OLD: 11 1xxxxx | TBD1 | Compressed CCNx Content Object messages NEW: 11 10xxxx | TBD1 | Compressed CCNx Content Object messages A drawback of this solution is that it reduces the space of this type of messages (from 32 options to 16 options, for this specific type of messages), but perhaps it could be sufficient. ===== The authors write, "The simple solution provided by the designated experts is sufficient. The drawback does not affect the option space, since that particular dispatch also contains a 'Reserved' bit. We can trade this for the longer prefix '11 10xxxx' (instead of '11 1xxxxx')."
