Relaying Apparatus Importance-Based Frame Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks with ring topology struggle to balance reliability and traffic reduction, as they often rely on a single communication route for frame transmission, which can lead to inefficiencies in data transmission.
Innovation Solution
A relaying apparatus with redundant-route ports and importance determination sections that dynamically route frames based on importance, using multiple routes for high-priority frames and single routes for low-priority frames, ensuring reliable communication while minimizing traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple communication routes are used for frame transmission, then reliability is improved, but traffic volume increases
Solution Approach 1:
The patent applies local quality by differentiating frame transmission based on importance level. High-importance frames are transmitted through multiple redundant routes to ensure reliability, while low-importance frames use single routes to minimize traffic. This selective approach applies different transmission qualities to different parts of the data flow based on their specific requirements.
Solution Approach 2:
The system dynamically adjusts the number of transmission routes based on frame importance and current network conditions. The determination section evaluates each frame's importance and dynamically selects whether to use single or multiple routes, making the transmission strategy flexible and adaptive rather than static.
2Quantity of substance
If single communication route is used for frame transmission, then traffic is reduced, but reliability deteriorates
Solution Approach 1:
The patent applies local quality by differentiating frame transmission based on importance level. High-importance frames are transmitted through multiple redundant routes to ensure reliability, while low-importance frames use single routes to minimize traffic. This selective approach applies different transmission qualities to different parts of the data flow based on their specific requirements.
Solution Approach 2:
The system applies partial action by using multiple transmission routes only when necessary (for high-importance frames) rather than for all frames. This avoids the excessive use of redundant routes for low-priority traffic, thereby reducing overall traffic volume while maintaining reliability where it matters most.
3Reliability
If frames are transmitted via each redundant-route port, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments the frame transmission process into distinct functional sections: an importance determination section that evaluates frame priority, and separate transfer sections that handle high-importance and low-importance frames differently. This segmentation simplifies the overall control logic by dividing complex decision-making into manageable, specialized components.
Solution Approach 2:
The system dynamically adjusts the number of transmission routes based on frame importance and current network conditions. The determination section evaluates each frame's importance and dynamically selects whether to use single or multiple routes, making the transmission strategy flexible and adaptive rather than static.

AI summary
A communication network includes relaying apparatuses, each including redundant-route ports providing communication routes between the relaying apparatuses. The relaying apparatus determines whether a first frame received via a usual port is highly important. The first frame being highly important is transmitted via the respective redundant-route ports; the first frame being not highly important is transmitted via one redundant-route port. The relaying apparatus receives a second frame being highly important via the respective redundant-route ports; the second frame has a transmission destination corresponding to an apparatus connected with the relaying apparatus via the usual port. The relaying apparatus makes determination whether or not all the second frames received via the respective redundant-route ports accord with each other. With affirmative determination, one of the second frames is transferred to the transmission destination. With negative determination, all the second frames are cancelled.
