Here we explore a general architectural model based on these
components and the relationships between them.
The figure shows a OS which may be accessed through the interoperable
interface for the purpose of managing resources. These managed resources
(which may be parts of managed elements or of the management solution) are
visible through the OS.
The management network, not shown in this figure, is the means for allowing
OSs to communicate via the interoperable interface.
Since the TMN's scope is limited to interoperability in network management,
the area outside the management network is beyond the scope of this
document. However, this architecture models some aspects of this outer area
in an abstract way in order to better understand the interactions between OSs.
The human users of network management are shown.
The management solution is shown as the second circle, which
encompasses management users, OSs, other management systems, the
management network, and other aspects of the solution.
The managed elements made available for management by the
various OSs are shown as the outer ring in the diagram. This is treated as a
simple set of elements; the structure or topology of these elements is not
modeled in this architecture.
