Network Management Apparatus Physical Logical Layer Failure Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network management technologies cannot identify the location of a failure within a communication network's configuration, preventing the display of the failure's influence range and affected customer information.
Innovation Solution
A network management apparatus that stores correspondence relationships between physical and logical layer information objects, allowing it to acquire and identify failure influence ranges and affected subscribers by associating physical layer failures with logical layer objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If network management displays NW configuration uniformly regardless of device type and protocol, then display simplicity is improved, but failure location identification capability deteriorates
Solution Approach 1:
The patent segments the network configuration into physical layer information objects and logical layer information objects, maintaining a unified display format while enabling differentiated failure analysis. The correspondence relationship database links these segmented objects, allowing the system to display uniformly while identifying failures at specific locations through the layered segmentation.
Solution Approach 2:
The correspondence relationship database acts as an intermediary between physical layer and logical layer information objects. It enables the system to maintain a unified display interface while providing the capability to trace failures through the intermediary relationships, resolving the contradiction between display simplicity and failure detection capability.
2Measurement precision
If the system stores and processes detailed correspondence relationships between physical and logical layer objects, then failure influence range identification is improved, but system complexity increases
Solution Approach 1:
The correspondence relationship database serves multiple functions: it stores physical layer object information, stores logical layer object information, and provides failure influence range identification. By making the database multi-functional, the patent reduces the need for separate systems and minimizes overall complexity while maintaining precise failure analysis capability.
Solution Approach 2:
The patent implements a nested structure where logical layer information objects contain references to physical layer information objects through the correspondence relationship database. This nesting allows detailed failure analysis to be embedded within the unified network configuration display, achieving precise measurement without proportionally increasing system complexity.
3Loss of information
If the system identifies and displays affected subscriber information, then customer impact awareness is improved, but information processing complexity increases
Solution Approach 1:
The patent merges subscriber information with the existing network configuration information objects. By combining these information types within the same object structure and using the correspondence relationship database, the system can identify affected customers without requiring a completely separate information processing system, thus reducing overall complexity while preventing information loss.
