Dear group, Table 2 of the ICNLoWPAN document [1] requests IANA updates to the "6LoWPAN Dispatch Type Field" registry. The last entry of table 2 clashes, however, with an existing registration. (11 11xxxx for "Page dispatch"). The solution is simple: we increase the prefix for the last entry from "11 1xxxxx" to "11 10xxxx". This decreases the option space for dispatches, but that particular dispatch (Figure 26) has a "Reserved" bit, which we can drop to increase it again. This: 0 1 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | 1 | 1 | 1 |CID|EXT|VER|FLG|FRS|PAY|RCT|MGH| PLTYP |EXP|VAL|RSV| +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ Becomes: 0 1 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ | 1 | 1 | 1 | 0 |VER|FLG|FRS|PAY|RCT|MGH| PLTYP |EXP|VAL|CID|EXT| +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+ This diff [2] summarizes the necessary changes, it also moves the CID and EXT bits of all dispatches to the end to keep the styling harmonized. What does the group think about this proposed solution? Are there any objections? To let it sufficiently marinate, feedback is very welcome until wednesday next week :-) Cheers, Cenk [1] https://datatracker.ietf.org/doc/html/draft-irtf-icnrg-icnlowpan-10 [2] https://tools.ietf.org//rfcdiff?url1=draft-irtf-icnrg-icnlowpan-10&url2=https://inet.haw-hamburg.de/tmp/draft-irtf-icnrg-icnlowpan-11.txt/@@download/file/draft-irtf-icnrg-icnlowpan-11.txt -- Cenk Gündoğan Hamburg University of Applied Sciences Dept. of Computer Science / Internet Technologies Group Berliner Tor 7, 20099 Hamburg, Germany Fon: +49 40 42875 - 8426 Mail: cenk.guendogan@haw-hamburg.de Web: https://www.inet.haw-hamburg.de/
