Modem Integrated Speed Test Eliminates Network Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining data throughput are inaccurate due to factors like wired cabling quality, wireless networking protocols, network interference, and firewall filtering, which can distort line speed measurements and limit bandwidth, especially when testing is performed at improper points.
Innovation Solution
Enhancing Customer Premises Equipment (CPE) with an integrated speed testing function and reporting capability, allowing for accurate line rate measurement directly at the modem, independent of external devices and potential bottlenecks, by initiating and processing data communications speed tests within the modem itself.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data throughput tests are run from software on the customer's computer, then the test can be easily performed, but the measurement accuracy deteriorates due to factors like cabling quality, wireless interference, and computer performance
Solution Approach 1:
The speed testing function is extracted from the customer's computer and relocated to the modem itself. The modem's processor directly measures the data rate by receiving test data from the network and calculating the measurement, eliminating the computer and its associated variables (cabling, wireless protocols, firewall filtering, processing power) from the measurement path while maintaining ease of operation through automated testing.
Solution Approach 2:
The modem serves as an intermediary device between the network and the customer's computer. It performs the speed measurement function that was previously performed by the computer, acting as a dedicated mediator that accurately measures line speed without being affected by computer performance or network configuration variables.
2Adaptability or versatility
If speed tests are performed through the computer and network equipment, then the test can utilize existing hardware, but the measurement becomes distorted by firewall filtering and traffic from other network elements
Solution Approach 1:
The speed measurement process is extracted from the computer and network traffic path, and relocated to the modem where it can be performed in isolation. The modem's processor directly measures the data rate without interference from firewall filtering or other network traffic, while still utilizing the existing modem hardware.
Solution Approach 2:
The speed testing function is segmented as a separate, dedicated process within the modem's processor. This segmentation isolates the measurement from other network operations and traffic, allowing accurate line speed measurement while the modem continues to handle normal network communications.
3Measurement precision
If the modem measures speed directly, then measurement accuracy improves, but the modem's processing capability must be enhanced
Solution Approach 1:
The modem serves itself by performing the speed measurement function internally using its own processor. The modem receives test data from the network, measures the data rate, and reports the result, eliminating the need for external testing equipment while enhancing the modem's functionality with minimal additional complexity.
Data Source
AI summary
A modem, method, and system is presented for performing a data communications speed test or line speed test between a network node and a customer premises. The modem may be configured to perform calculations for determining the data communications speed without interference of network elements or overhead modules that cause data communications to be inaccurate or otherwise affected.
