Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Complex computer networks are prone to configuration errors and troubleshooting these errors is difficult due to their intricate nature, making it challenging to identify the root cause of undesired network behavior.
Innovation Solution
A system for fault code aggregation across application-centric dimensions that maps hardware errors to logical policy entities in a software-defined network, enabling visualization and aggregation of hardware-level errors along logical dimensions, such as per-tenant, per-application profile, or per-endpoint group pairs, facilitating quick root cause analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network configuration flexibility and control options are increased to meet diverse user needs, then network adaptability improves, but device complexity and troubleshooting difficulty increase
Solution Approach 1:
The patent segments network fault analysis by creating separate logical policy dimensions (tenant, application profile, endpoint group) that independently organize fault codes. This segmentation allows operators to analyze faults within specific contextual dimensions without being overwhelmed by the entire complex network configuration, thereby maintaining high network adaptability while reducing the perceived complexity during troubleshooting.
Solution Approach 2:
The patent introduces a new dimensional approach to network fault analysis by organizing fault codes along multiple logical policy dimensions simultaneously. Instead of traditional flat fault enumeration, faults are projected onto dimensional spaces (tenant dimension, application profile dimension, endpoint group dimension), enabling operators to view and analyze network health from multiple perspectives without increasing actual network complexity.
2Adaptability or versatility
If network configuration options are expanded to provide greater control, then network adaptability improves, but ease of operation deteriorates due to increased error-proneness
Solution Approach 1:
The patent implements feedback mechanisms by continuously monitoring and aggregating fault codes across logical policy dimensions. The system provides real-time feedback about network health status organized by tenant, application profile, and endpoint group, enabling operators to quickly identify configuration errors and their impacts without manually navigating complex configuration options, thus maintaining adaptability while improving operational ease.
3Ease of manufacture
If traditional fault analysis methods are used in complex networks, then implementation simplicity is maintained, but loss of information occurs due to inability to aggregate faults across multiple dimensions
Solution Approach 1:
The patent merges fault code information from multiple sources and dimensions (tenant, application profile, endpoint group) into a unified analytical framework. By combining fault data across these logical dimensions, the system preserves comprehensive fault context information that would be lost in traditional single-dimension analysis, while the automated aggregation process maintains implementation simplicity through systematic data consolidation.

AI summary
Systems, methods, and computer-readable media for fault code aggregation across application-centric dimensions. In an example embodiment, a system obtains respective fault codes corresponding to one or more network devices in a network and maps the one or more network devices and/or the respective fault codes to respective logical policy entities defined in a logical policy model of the network, to yield fault code mappings. The system aggregates the one or more of the fault code mappings along respective logical policy dimensions in the network to yield an aggregation of fault codes across respective logical policy dimensions and, based on the aggregation, presents, for each of the respective logical policy dimensions, one or more hardware-level errors along the respective logical policy dimension.
