User Information Model Translation for Network Fault Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face difficulties in building a shared knowledge base and applying common rules for fault isolation, alert correlation, and service impact analysis across multiple, distinct standardized problem domains in network and service management, as they require users to adapt to unfamiliar, highly normalized representations of resources.
Innovation Solution
A domain-focused User Information Model (UIM) translates conventional resource terminology into functional operators within the Common Information Model (CIM), allowing users to interface with CIM using familiar terms and definitions, thereby generating CIM without needing to learn its complex structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a Common Information Model (CIM) is used to describe all resources in a uniform fashion, then fault isolation, alert correlation, and service impact analysis can be performed efficiently across multiple domains, but the model becomes domain-oriented and difficult for users to understand and operate with
Solution Approach 1:
The patent introduces a User Information Model (UIM) as an intermediary layer between the CIM and the user. The UIM translates CIM's normalized resource representations into domain-specific terminology and structures that users are familiar with. This mediator maintains the benefits of CIM's unified structure while presenting resources in user-friendly domain-oriented formats, thus resolving the contradiction between cross-domain capability and ease of operation.
2Measurement precision
If resources are modeled in a highly normalized CIM fashion with detailed functional attributes, then comprehensive analysis tasks can be performed, but users must learn and adapt to a completely different representation manner
Solution Approach 1:
The patent segments the information model into two distinct layers: the CIM layer that maintains detailed normalized attributes for comprehensive analysis, and the UIM layer that presents simplified domain-specific views to users. This segmentation allows the system to preserve measurement precision through CIM's detailed structure while reducing perceived complexity for users by presenting only relevant attributes through UIM's domain-focused representation.
3Ease of manufacture
If a classical layered approach to network modeling is used, then service and network management can be performed, but it becomes difficult to manage networks spanning several distinct standardized problem domains
Solution Approach 1:
The patent implements a universal UIM framework that can represent resources from multiple different domains (telecom, datacom, wireless, etc.) using a common set of domain-specific templates. This universal approach allows the same UIM infrastructure to handle diverse network types and management tasks, providing both ease of management through standardized procedures and adaptability to handle multiple standardized problem domains simultaneously.

AI summary
A domain-focused User Information Model (UIM) generating methodology automatically translates conventional resource terminology employed by a user in his everyday relationships with a managed system of interest into associated functional operators within the realm of the Common Information Model (CIM), so that the CIM is generated, yet the user ‘views’ and interfaces with the CIM through the domain-focusing lens of the UIM.
