Automatic
topology abstraction
In order to scale to large numbers of underlying systems, performs topology abstraction. Difference
between detailed and abstracted representation illustrates the difference between a detailed
representation and an abstracted representation of network connectivity.
Difference
between detailed and abstracted representation

Abstraction produces a coarse level
of topology
detail. A system, for example, is viewed as a single entity rather
than as a collection of its components, and connectivity is between
systems as opposed to between components in the system.
Although maintains a
coarse level of topology detail,
it stores sufficient information for its varied Notification Log,
Topology Browser, and Map views. When needed, detailed information
can be automatically retrieved from the underlying applications by .
