Subject: RE: [Mipshop] DHCP
Hi Alper,
MIPSHOP is only aware of a MIH protocol not its
constituents. The transport characteristics being the same,
the requirements from 802.21 have been for a single
transport. This is not to say that DHCP may not meet all the
MIH protocol requirements. Both L2 and L3 are suitable for
the entire MIH protocol covering all services. As such, it
is also acceptable that the MIPSHOP provided transport could
be specifically used for a certain functionality and a L2
transport can be used for others.
Regards,
Srini

There have been already proposals using DHCP for 802.21
services
discovery.
The DT is currently considering different scenarios and
associated
requirements targeting a single solution.
This might change if complexity increases too much.
I don't understand why designing one protocol that does
three things (IS, ES, CS) is better than using an existing
protocol (DHCP) for what it has used for (configuration
[IS]), and designing another protocol that takes care of the
other two (ES, CS).
I'm not aware of any technical reason that requires all
three functionalities to be bundled up in single protocol.
And in fact, I see reason to separate them. It is an
accepted scenario that ES and CS are taken care of by the L2
in some networks, leaving IS to L3.
Comments?
