Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for scheduling time-sensitive data in Time-Sensitive Networks (TSN) require modifications to application code or network switch firmware, which are undesirable due to validation issues and limited switch choices, leading to potential system instability and catastrophic failures.
Innovation Solution
A network driver is configured by an external module to classify and package data based on segregation features, allowing data to be transmitted without modifying application code or switch firmware, using IEEE 802.1 standards-compliant switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If application code is modified to forward data to different TSN channels based on data class, then data transmission accuracy is improved, but system reliability deteriorates due to validation issues and code rewriting burden
Solution Approach 1:
The patent introduces a network driver as an intermediary layer between the application and the TSN network. The network driver handles data classification and channel selection based on segregation features in the data packets, eliminating the need for application code modifications. This intermediary approach maintains system reliability while achieving accurate data transmission routing.
Solution Approach 2:
The patent replaces the mechanical approach of modifying application code with a software-based solution in the network driver layer. Instead of changing the application's data forwarding logic, the solution substitutes this function with automated classification and routing capabilities in the network driver, which processes data packets based on their segregation features.
2Measurement precision
If network switch firmware is modified to extend deep packet inspection capability, then data segregation accuracy is improved, but device complexity and adaptability worsen due to limited switch choices
Solution Approach 1:
The patent positions the network driver as an intermediary that performs packet inspection and classification before data reaches the network switch. This approach eliminates the need to modify switch firmware, allowing the use of standard IEEE 802.1 compliant switches while achieving accurate data segregation through the network driver's processing capabilities.
Solution Approach 2:
The patent extracts the deep packet inspection and data classification functionality from the network switch firmware and relocates it to the network driver layer. This extraction allows standard switches to be used without firmware modifications, thereby improving switch compatibility and adaptability while maintaining data segregation accuracy through the separated inspection function.
3Adaptability or versatility
If standard IEEE 802.1 compliant switches are used without firmware modification, then adaptability is improved, but data segregation capability worsens
Solution Approach 1:
The network driver serves as an intermediary that compensates for the limited data segregation capability of standard IEEE 802.1 compliant switches. By performing classification and routing operations in the network driver before data transmission, the system achieves accurate data segregation while maintaining compatibility with standard switches that require no firmware modifications.
