The common feature in question is not a framing structure (it does not exist
for TDMA, for example), but rather a contention/grant/reservation scheme.
If we accept this as the defining feature of BoD, 802.11 in PCF mode (which I
believe is the basis for 802.11e, although I haven't been following it
closely) is not a bandwidth-on-demand scheme, since it uses polling.
BTW, the term "Bandwidth-on-Demand is badly overloaded. Can we come up with a
better one? Perhaps Contention/Reservation would work.
Also, the draft is pretty negative toward BoD. I hope that Mark will tone
that down a bit.
