stds-802-16: RE:ATM vs. IP

[Notice: It is the policy of 802.16 to treat messages posted here as non-confidential.]


 The addressing scheme that we adopt for IEEE 802.16 does not have to deal
with IP vs ATM or ATM vs IP (by the same token nor FR vs ATM, etc.). We are
dealing with a MAC protocol and we should provide an addressing mechanism
that fits our environment and architecture. However, there is some
precedence to learn from, like 802.14 and DOCSIS.

I agree completely. It's time we get this issue out and on the table. Now
that we have a contribution submission process, everyone will have a chance
to make suggestions and offer supporting documentation.

802.16 will deal with the ATM vs. IP issue on its merits. 802 rules will
not make our decision for us.

Take a look at 802.14: it's developing a spec based on ATM frames, in spite
of the fact that the DOCSIS spec is IP packet based. Regardless of whether
or not that's a good idea or not, they are going ahead with it, and 802 is
not constraining them.

I've gotten confirmation from 802 SEC Chair Jim Carlo that this is 802.16's
decision to make. Let's follow Marianna and Steve's lead: let's start
