Solution Overview
Problem
Current network element management systems lack a unified performance management solution for disparate network elements from different manufacturers, and their alarm systems are not adaptable to time-varying conditions, failing to provide root cause analysis.
Innovation Solution
An adaptive unified performance management (AUPM) framework with a proxy-based architecture that unifies data collection and analysis across different network elements, using a multi-layer configuration including a data extractor layer, performance monitoring layer, and adaptive root cause analysis layer to provide robust performance monitoring and alarm reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed thresholds are used for alarm conditions, then alarm notification is provided, but adaptability to time-varying conditions is lost
Solution Approach 1:
The patent implements dynamic thresholds that adapt to time-varying conditions by continuously learning from historical data and adjusting to changing network environments. The system transitions from static fixed thresholds to dynamic adaptive thresholds that evolve with network conditions, resolving the contradiction between reliable alarm notification and adaptability.
Solution Approach 2:
The system performs self-configuration and self-optimization through automated learning algorithms that adjust thresholds without manual intervention. The network management system automatically adapts to changing conditions by learning from historical performance data, eliminating the need for manual threshold tuning while maintaining reliable alarm detection.
2Adaptability or versatility
If multiple different network element management means are used for different manufacturers, then compatibility with various network elements is achieved, but unified performance management is lost
Solution Approach 1:
The patent creates a universal network management system that can handle multiple network element types from different manufacturers through a common interface and unified performance management framework. The system uses standardized data models and abstraction layers to achieve multi-functionality, allowing single management software to control diverse network elements without requiring manufacturer-specific tools.
Solution Approach 2:
The system introduces intermediary components such as adapters and translation layers that mediate between different manufacturer-specific management interfaces and the unified management platform. These intermediaries translate proprietary protocols into standardized formats, enabling compatible communication without requiring changes to the core management system or the network elements themselves.
3Device complexity
If fixed threshold alarm systems are used, then simple alarm notification is provided, but root cause analysis capability is lost
Solution Approach 1:
The patent implements feedback mechanisms where alarm data is continuously collected, analyzed, and used to adjust management policies and identify root causes. The system correlates alarm patterns with performance metrics and network conditions, providing feedback loops that enable automated root cause analysis while maintaining system simplicity through standardized data collection and analysis procedures.
