Network Performance Estimating Apparatus for FA Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for estimating network performance in FA systems require actual connection of communication management stations and slave stations, making pre-purchase estimation impossible, and fail to accurately account for network connection information like hub connections, leading to inaccurate performance predictions and a lack of comparison between designed and constructed network configurations.
Innovation Solution
A network performance estimating apparatus that generates network configuration information based on user-designed connections, acquires communication apparatus performance data, determines token circulation order, and calculates performance using a performance estimating unit, allowing for pre-purchase network performance assessment and comparison with actual configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If actual connection of communication management station and slave stations is required for performance estimation, then performance calculation can be performed using real network data, but pre-purchase estimation becomes impossible and network construction time is increased
Solution Approach 1:
The patent enables performance estimation to be performed before actual network construction by using configured connection information and device specifications. The estimation apparatus calculates token circulation time and network performance based on pre-configured network topology and device parameters, allowing purchasers to evaluate performance in advance without requiring physical network assembly.
2Device complexity
If only data size information is used for performance calculation, then calculation process is simplified, but accurate performance estimation in networks with multiple hubs cannot be achieved
Solution Approach 1:
The patent extends the calculation parameters beyond simple data size to include connection information such as hub connection details, token circulation paths, and network topology characteristics. The estimation apparatus uses these additional parameters to accurately calculate token circulation time through multiple hubs, thereby achieving precise performance estimation for complex network configurations while maintaining a systematic calculation approach.
3Loss of information
If network configuration estimation is performed after network construction, then actual network data is available for calculation, but the estimation becomes meaningless for purchase decision-making
Solution Approach 1:
The patent enables performance estimation to be performed before actual network construction by using configured connection information and device specifications. The estimation apparatus calculates token circulation time and network performance based on pre-configured network topology and device parameters, allowing purchasers to evaluate performance in advance without requiring physical network assembly.
4Device complexity
If connection information of hubs and network topology are not considered, then calculation process is simpler, but accurate performance estimation in multi-hop networks cannot be achieved
Solution Approach 1:
The patent extends the calculation parameters beyond simple data size to include connection information such as hub connection details, token circulation paths, and network topology characteristics. The estimation apparatus uses these additional parameters to accurately calculate token circulation time through multiple hubs, thereby achieving precise performance estimation for complex network configurations while maintaining a systematic calculation approach.
