Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Daily network operations face challenges in monitoring and managing sudden, extraordinary increases in network load due to events like large-scale software updates, leading to lower user quality and satisfaction.
Innovation Solution
A quality measurement device and method that analyze network load, acquire reference load data, determine additional load based on scale differences between networks, and generate test traffic to replicate sudden loads, enabling effective quality measurement and monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If quality monitoring is performed using conventional methods (TWAMP, RFC 2544), then network quality can be measured under normal conditions, but sudden extraordinary loads cannot be reproduced or measured
Solution Approach 1:
The patent applies preliminary action by acquiring reference load data from a reference network before measuring quality in the measurement target network. The test condition determination unit uses this pre-acquired reference data to determine appropriate test conditions that can reproduce sudden extraordinary loads, allowing the system to be prepared for unusual conditions rather than reacting to them after they occur.
Solution Approach 2:
The patent applies copying by creating a virtual reproduction of sudden extraordinary loads based on reference load data from a reference network. The test traffic generation unit generates test traffic that copies the characteristics of actual sudden loads observed in the reference network, enabling measurement of quality under reproduced sudden load conditions without requiring actual sudden events to occur.
2Measurement precision
If reference load data is acquired and test conditions are determined based on scale differences, then sudden loads can be reproduced, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a quality measurement device that can perform both conventional quality measurement and sudden load reproduction measurement using the same core components. The test condition determination unit and test traffic generation unit serve multiple functions: they work with both normal traffic patterns and reproduced sudden load patterns, eliminating the need for separate specialized systems for different measurement scenarios.
Solution Approach 2:
The patent applies intermediary by introducing a test condition determination unit that acts as a mediator between the reference load data and the test traffic generation. This intermediary component processes the reference data, calculates appropriate test conditions based on scale differences, and translates them into actionable test traffic parameters, simplifying the overall system architecture while maintaining measurement accuracy.
