ATM Clients
QIO API clients are protocol subsystems that communicate with the ATM service
provider directly through QIO. Currently, these are:
•
Expand connecting through the QIO application program interface (API) to TCP/IP
in order to provide Expand/IP capability
•
Transmission Control Protocol/Internet Protocol (TCP/IP) to provide connectivity to
a TCP/IP network
ATM Clients
ATM clients are processes, user applications, or subsystems that use the ATM
subsystem and related ATM service providers to connect to the ATM network attached
to a NonStop S-series server.
ATM Subsystem Management
SCF is the interface that manages the processes and objects of the ATM subsystem.
Figure 2-3 shows the SCF interface to the ATM subsystem.
For more information about SCF, see the SCF Reference Manual for G-Series RVUs .
For a description of the SCF commands, object hierarchy, and object states for the
ATM subsystem, see Section 4, SCF Commands.
