Solution Overview

Problem

Existing communication networks face challenges in efficiently and accurately aligning network element configurations with DNS records, particularly in large networks with cloud-based infrastructure, leading to inefficiencies and increased data management complexity, as manual procedures are error-prone and time-consuming.

Innovation Solution

An alignment management component (AMC) automatically validates and reports misalignment between wireless and wireline network element configurations and DNS records by retrieving configuration and metadata items, analyzing them, and generating audit reports for missing DNS records.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual procedures are used to align network element configurations with DNS records, then flexibility and control are maintained, but accuracy decreases and time consumption increases

Engineering Contradiction:

Improvealignment accuracyVSAvoidvalidation time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical procedures with an automated computer-based system that retrieves configuration data, analyzes alignment with DNS records, and generates audit reports automatically. This substitution eliminates human error and significantly reduces validation time while improving accuracy through systematic automated comparison of configuration parameters against DNS record data.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If manual alignment procedures are used, then system complexity remains low, but error rate increases and productivity decreases

Engineering Contradiction:

Improvedeployment speedVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system performs self-validation by automatically retrieving its own configuration data, comparing it against DNS records, and generating audit reports without external intervention. This self-service capability enables continuous automated validation during network deployment and operation, significantly improving productivity while the modular architecture keeps system complexity manageable through standardized interfaces and processes.

Inventive Principle:

Principle #25Self-service

AI summary

Techniques for validating alignment between network element configuration and DNS records associated with a communication network are presented. Alignment management component (AMC) can retrieve respective configuration parameter data items relating to respective configuration parameters associated with respective resource-related identifiers, and respective metadata items associated with the respective resource-related identifiers, from a configuration data store; and retrieve respective DNS records from respective DNS name servers, based on analyzing the respective metadata items associated with respective DNS records. For each resource-related identifier that is supposed to have a corresponding DNS record, based on the result of analyzing the respective configuration parameter data items and respective DNS records, AMC can determine whether the resource-related identifier has a corresponding DNS record stored in the DNS name server indicated by the metadata item. AMC can generate an audit report comprising a missing DNS record data item for each DNS record determined to be missing.
