More off form than I'd realized [/realised]: Belatedly occurred to me that the Layer, Layer, Who's Got the Layer context is a good one for remembering that even if the ISORMites still think you've got to traverse every layer every time, I never did (and they might not any more, if one thinks things like "MAP" [which, of course, should be "MAPS" to begin with, since it's a Suite, not just A protocol] are ISORMitic, since it blithely skips a layer or two on its way). So I'd refine my answer to the original question to include something like "They sure seem to me to be operating at L II WHEN THEY'RE OPERATING." That might somehow subsume the notion that a few people had that they're not really "in" the "stack"--or perhaps subvert it, if not subsume it. (And I guess it's also worth pointing out that is assumes HMP, which I haven't looked at, doesn't muddy the waters and operate over TCP connections, which would almost make it have to be L III by my insistently non-rigorous definitions.) fuzzy cheers, map p.s. So as not to generate a new Glossary call, for the benefit of those who haven't been around long enough, "ISORM" = ISO Reference Model; ISORMite = follower of the ISORM who I feel is of dubious worth (as opp. to ISORMist, which is one I feel to be sound in other respects but wrong about the RM issue). (The reason why I don't use "OSI" is that I feel it begs the question; i.e., they may say they're doing Open System Interconnection in their name, but are they in their RM ... or their standard protocols? Besides, I like the sound of ISORM.) te: 2ybo
