Solution Overview

Problem

Manual schema management in network management systems (NMS) is error-prone, leading to inaccurate configuration deployment, network malfunctions, and resource inefficiencies, including excessive memory and bandwidth consumption.

Innovation Solution

Implementing a schema repository for automated schema discovery and management, which stores schema information for multiple network devices, enabling accurate and seamless deployment by using a lookup mechanism based on schema parameter values.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual schema management is used in NMS, then configuration deployment can be performed, but manual errors increase leading to inaccurate configuration deployment and network malfunctions

Engineering Contradiction:

Improveconfiguration deployment accuracyVSAvoidmanual operation complexity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system enables automated schema discovery where the NMS automatically retrieves schema information from network devices without manual intervention. The schema repository service autonomously stores, manages, and provides schema indications to the schema manager, eliminating manual schema management operations and reducing human errors in configuration deployment.

Inventive Principle:

Principle #25Self-service

2Productivity

If manual schema management is used, then configuration deployment can be performed, but resource overhead increases including excessive memory and bandwidth consumption

Engineering Contradiction:

Improveconfiguration provisioning efficiencyVSAvoidresource consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The schema repository service creates and maintains a centralized copy of schema information from multiple network devices. Instead of each NMS component accessing original schema sources directly (consuming excessive bandwidth), the repository provides local copies through efficient lookup operations, reducing network traffic and memory consumption across the system.

Inventive Principle:

Principle #26Copying

3Reliability

If automated schema discovery is implemented, then manual errors are reduced and configuration accuracy is improved, but system complexity increases

Engineering Contradiction:

Improveschema management accuracyVSAvoidschema management system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The automated schema discovery system is segmented into distinct functional components: the schema repository service for storage and management, the schema manager for coordination, and the lookup mechanism for retrieval. This segmentation isolates complexity into manageable modules, each with specific responsibilities, making the overall system more maintainable and less error-prone despite the automation capabilities.

Inventive Principle:

Principle #1Segmentation

AI summary

In some implementations, a device may receive an indication of one or more schema parameter values associated with a network device. The device may perform a lookup, in a repository configured to store a plurality of schema parameter values associated with a plurality of schema indications, for a schema indication based on the one or more schema parameter values associated with the network device.
