\ From: *** 802.11
Architecture Standing Committee *** [mailto:STDS-802-11-ARC@xxxxxxxxxxxxxxxxx] On Behalf Of Mark Hamilton All, I
wasn’t sure if we really got to the bottom of Jouni’s questions
about how our proposed changes to ESS and HESS definitions/description (in
11-20/0177, to be liaised to REVme) relate to GLK operation. I found the
following in 802.11ak, that I thought solved the problem for us (4.3.5.1): The
architectural component used to interconnect infrastructure BSSs
is the DS for non-general link (non-GLK) operation. The DS and extended service
set (ESS) are mechanisms
for expanding connectivity for non-GLK operation. For GLK operation, an IEEE
802.1Q bridge
might be used to form an extended network (see 4.3.27). Hopefully,
that’s helpful, as I believe it means we don’t have to worry about
GLK in our changes. [RR] I think there is a problem with it, however I could be
wrong. It’s not clear whether an “extended network”
is equivalent to / the same as an ESS. I assume the intent is that they are,
but again I could be wrong. If they are the same, then “”extended
network” should be replaced with “ESS” to make it clear.
If
anybody think we should still add a NOTE (or something similar) near the ESS
definition, please respond to this reflector. (Personally, I think that
is beyond our intent of “fixing” the ESS definition, but it could
be argued we’re clarifying things, “while we’re at
it”.) That
said, I agree with Jouni that there is an occurrence of “ESS with a
DS” in 802.11ak (and now in REVmd), in 4.5.3.4: The
reassociation service is invoked to “move” a current association of
a non-AP STA from one AP to another.
In an ESS with a DS, the reassociation service informs the DS of the current
mapping between AP and
STA as the STA moves from BSS to BSS within the ESS. I
agree that this is redundant, and should just be “In an ESS, the
reassociation service…” Do we want to suggest fixing that in
our liaison (“while we’re at it”), or leave that for a REVme
comment? [RR] I think the real question is: “Is the
reassociation service used when the ESS is formed using .1Q bridges or not?”
This is what should be made more clear. So, I think the text in
question needs a bit more work than you are currently suggesting in this email. Happy New Year Mark (et. al.)!
