The ATM Forum recently completed an ATM API document,
"Native ATM Services: Semantic Description", atm95-0008.
This will go for final vote shortly.

The ATM API document lays out the scheme to be used for
call distribution within an ATM endsystem. As far as "QOS" type
parameters go, the API will essentially allow access to all the ATM
signaling parameters. It is up to the API user to use them
appropriately.

In this case it is up to the IP layer to map the RSVP flowspecs
to ATM QOS and traffic parameters.

In addition to the above work, there is currently work in progress in
the X/Open XNET group to map the ATM Forum API to the XTI syntax.
(XTI is the X/Open Transport Interface.) This will enable native ATM
applications using XTI.
