Introduction to the
Tandem TCP/IP
Subsystem
A Tandem TCP/IP subsystem runs on the Tandem NonStop Kernel operating system
over a TLAM or X25AM I/O process. It has a wide range of capabilities provided by a
number of individual components that act alone or together. Figure 1-6 shows the
Tandem TCP/IP subsystem components and their relationships to the TLAM, X25AM,
and OSI/TS subsystems.
