hi all,
I am interested in atm and ip over atm.
I study and read atm UNI 3.1/4.0,ILMI.

I have som questions.
to form ATM address , we need network prefix. same network prefix means
same domain.

 __                            ____           ___
|    |______________|      |_____ |      |
|__|              _______|      |           |      |
                  -              |___|           |___|
 ___ ____ -
|___|
end systems               MUX          ATM SWTICH

end systems, MUX, ATM switch connect each other.
1.does it have same network prefix?

ATM switch have user-side, network-side.  address thru ILMI is
registered.
calling party - ATM port mapping table( network-side). called party- ATM
port
mapping table (user-side)
address mapping consist of upper mapping.
2. is it right?
I need adding infomation for  address mapping.

3.In ILMI Specification Ver4.0, chap 8. Link Management MIB-section
8.2.2.1
  interface index(R)    I don't understand  its value.
"Interface indices are used in a number of ATM Interface MIB subtree to
identify a particular physical
 or virtual interface on the ATM device. the interdace index
object(atmPortIndex) has the value zero in all SNMP messages."
  I think that interface index is physical port number then, upper
explanation, may be, is not.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 what do it means?
~~~~~~~~~~~~
   chap 9. Address Registrantion MIB,  section 9.4.1.1 Interface
Index(r)
   -"The Interface Index object(atmfNetPrefixPort) is the same as that
for the Physical
      interface as defined in setction 8.2.2.1"

 I think user-side consists of  table thru ILMI, portnumber, network
prefix , status.
 port number is ATM switch physical port numer.
is it right?
~~~~~~
it is very basic question. and may be, have not relevance to working
group topic.
but I didn't find group to solve these problems.

thank you for your time and look forward to sending reply.

regards,
