Unified NFV Testing Tool for Anomaly Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current testing tools for telecommunications networks, particularly those using Network Function Virtualization (NFV) architectures, face inefficiencies in detecting anomalies and identifying root causes due to the complexity of virtualized network functions and sub-functions, leading to slow debugging and operational inefficiencies.
Innovation Solution
A unified interface and tracing tool that allows simultaneous probing and analysis of virtual network components, capturing log entries from various logs, and enabling concurrent testing of functional blocks and sub-functions, thereby automating the detection of anomalies and root cause identification across multiple virtual functions.

Engineering Contradiction Analysis
1Reliability
If traditional sequential testing methods are used across multiple interfaces, then comprehensive validation is achieved, but debugging time and operational efficiency deteriorate
Solution Approach 1:
The patent combines multiple testing interfaces and functions into a single unified testing tool that can simultaneously probe virtual network functions, capture logs, and analyze performance metrics. This merging eliminates the need to sequentially access multiple separate interfaces, thereby maintaining comprehensive validation coverage while significantly reducing debugging time and improving operational efficiency.
2Measurement precision
If multiple separate testing interfaces are used to probe virtual network functions, then detailed analysis capability is improved, but device complexity and ease of operation worsen
Solution Approach 1:
The unified testing tool implements multi-functionality by integrating various testing capabilities including probing, log capture, performance analysis, and anomaly detection into a single interface. This universal tool maintains detailed analysis capability across all virtual network function aspects while eliminating the complexity of managing multiple separate testing interfaces.
3Measurement precision
If comprehensive logging from all virtual network components is captured, then root cause identification accuracy is improved, but data processing complexity increases
Solution Approach 1:
The unified testing tool acts as an intermediary that centralizes the collection, aggregation, and initial processing of log data from all virtual network components. By serving as a single mediation point, it maintains high root cause identification accuracy through comprehensive data capture while simplifying the overall data processing architecture compared to distributed processing across multiple interfaces.
Data Source
AI summary
A system configures a test case including a test script to validate a new product. The test script has a logic flow for communications through a sequence of network nodes and the test case includes pass/fail criteria for parameter data of packets communicated between the sequence of network nodes. The system initiates an automation engine that is configured to execute the test script and validates the new product based on actual parameter data relative to the pass/fail criteria. The system simulates the enhanced calling or messaging communications service to utilize by the new product during the test. The system instantiates a network probe that captures packets of the network nodes and extracts actual parameter data, which is compared to expected parameter data to generate test results relative to the pass/fail criteria. The system can present an indication that the new product passed/failed the test case based on the test results.
