Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Ethernet networks with a ring topology, data transmission times are prolonged due to the need to utilize both communication paths, which are affected by the slower communication speed of one path.
Innovation Solution
A repeater system that divides data into multiple pieces and distributes them across specific ports based on a MAC address table, allowing for efficient transmission by determining the optimal path for each data piece, thereby reducing the overall data amount in one communication path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted using both communication paths in a ring topology, then communication reliability is improved, but transmission time increases due to the slower speed of one path
Solution Approach 1:
The data is divided into multiple data pieces, and each piece is assigned to a different communication path for parallel transmission. This segmentation allows the system to utilize both communication paths simultaneously, improving overall transmission efficiency while maintaining reliability through distributed path usage.
Solution Approach 2:
The invention transitions from sequential transmission along a single path to parallel transmission across multiple dimensions (paths). By distributing data pieces across different communication paths simultaneously, the system adds a dimensional aspect to data transmission, effectively utilizing the ring topology's dual-path capability to reduce overall transmission time.
2Loss of time
If data is transmitted through a single communication path, then transmission time is reduced, but communication reliability deteriorates
Solution Approach 1:
The data is segmented into multiple pieces that can be transmitted through different communication paths. This allows the system to achieve faster transmission by utilizing parallel paths while maintaining reliability through distributed transmission, as the failure of one path does not affect the transmission of other data pieces.
Solution Approach 2:
The invention changes the transmission parameter from single-path sequential transmission to multi-path parallel transmission. By adjusting how data is distributed across available paths, the system optimizes both transmission speed and reliability, transforming the fundamental transmission approach to resolve the contradiction between speed and reliability.
3Device complexity
If all data is transmitted through one communication path, then path utilization is simplified, but the data amount in that path increases, prolonging transmission time
Solution Approach 1:
The data is divided into multiple pieces and distributed across different communication paths. This segmentation reduces the data amount in each individual path, thereby decreasing transmission time while introducing a structured method for path utilization that manages complexity through systematic data distribution.
Solution Approach 2:
The invention introduces multi-dimensional path utilization by distributing data across multiple communication paths simultaneously. This approach balances the data load across available paths, reducing congestion in any single path and thereby reducing transmission time, while the systematic distribution methodology manages the increased complexity.

AI summary
A repeater receiving an original frame from a connected Electronic Control Unit (ECU) by a normal port divides data stored in a data area of the received frame, and each of a plurality of divided data pieces is stored in the data area in each of a plurality of division frames to be sent out to a destination. Each of the plurality of division frames of the original frame is distributed to one of two ring ports according to a determination of the repeater, and each of the division frames is sent out therefrom to the destination. In such manner, the frame transmission time required for a transmission of the frame is reduced.
