About The Patent
Novadigm's Patent (Number 5,581,764) "Distributed Computer Network
Including Hierarchical Resource Information Structure and Related
Method of Distributing Resources" describes the processes needed
to generate from a common reference model a unique content
configuration for each target end user, and to "difference" the
"desired state" configuration with the actual-state of the target,
yielding highly granular and very specific updates to distributed
content automatically. The patent covers two central areas:
Desired state configuration-processes which incorporate essential
elements of both "push" and "pull" distribution models. By
generating from common reference model a unique user configuration
which describes the specific software or content a target user
should have, producers can automatically 'push' content to
specific servers, desktops, or users; or groups of users. In
addition, the 'pull' process provides a means for users to control
when the flow of information takes place, what information is
delivered, and where it is stored. Fractional
Differencing-processes for comparing and contrasting the desired
state configuration identifying what components a target should
have with the resources it actually has, resulting in a concise
and highly detailed difference configuration describing what
components are needed-or should by removed-to ensure the targeted
user is properly configured with a minimum of network traffic.
