Modeling Future Attributes

       System B interprets the system control data into management data and
reports to the manager application program at system D.

      Disclosed is a method for modeling future attributes in Open
Systems Interconnection (OSI) managed objects.  An OSI managed object
is a specification that describes the characteristics and features of
a resource that is to be managed.  The managed object represents the
resource itself, while features of the resource are modeled as data
items called attributes.  At the time that a managed object
specification is created, only those features of a resource that are
known can modeled as attributes, of course.  At a future time, as a
resource is enhanced by the addition of new features, the standard
method for adding the corresponding characteristics to the managed
object model is by the definition of a subclass.  A subclass is a
managed object specification that inherits all the characteristics of
the original managed object, and extends it by the addition of the
new characteristics.  If the appropriate manager application programs
are enhanced to support the new characteristics of the subclass, the
new features of the resource can be presented to a network operator
as needed.

System B interprets the system control data into management data and
reports to the manager application program at system D. Since System
B does not understand feature 2, it does not report on that feature
to the manager application program.

      This standard method for enhancing an OSI managed object model
works well in most cases because product enhancements with new
features generally are accompanied by corresponding enhancements to
the management support in the same product.  However, in networking
environments, a system often reports information about other systems
to its manager, and not just information about itself.  The
management information about the other systems is inferred from
system control data that is exchanged by the networking components of
the systems.  This method for reporting on connected systems is
illustrated in Fig. 1.
