Ethernet Data Transmission via Electrophysical Sub-channel Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As Ethernet transmission rates increase, existing physical layer architectures face complexity in bit width processing and rapid growth in virtual channels, leading to increased data processing complexity.
Innovation Solution
The method involves distributing to-be-transmitted data to a first integral number of electrophysical sub-channels, where coding and scrambling are performed, and then transmitting through a second integral number of photophysical sub-channels, allowing for flexible adjustment of electrophysical sub-channels based on data amount and bandwidth, reducing processing complexity while maintaining high-rate data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If higher order modulation is used to improve communication rate, then transmission rate is improved, but data processing complexity increases due to bit width processing
Solution Approach 1:
The patent segments the data transmission path into multiple electrophysical sub-channels, each handling a portion of the to-be-transmitted data. This segmentation allows the system to achieve high transmission rates by parallel processing across multiple sub-channels rather than increasing bit width in a single channel, thereby reducing the complexity of bit width processing while maintaining high speed transmission.
2Productivity
If Ethernet rate is increased to meet high bandwidth requirements, then transmission capacity is improved, but the number of virtual channels grows rapidly increasing processing complexity
Solution Approach 1:
The patent divides the high-rate data transmission into multiple electrophysical sub-channels, where each sub-channel handles a subset of the data. This segmentation approach allows the system to scale transmission capacity by adding sub-channels rather than increasing the complexity of virtual channel management within a single channel, thus improving productivity while controlling processing complexity.
Solution Approach 2:
Instead of increasing transmission capacity by adding more virtual channels in the same dimensional space (which increases processing complexity), the patent transitions to a multi-dimensional approach by creating multiple electrophysical sub-channels. This dimensional change allows parallel data streams to be handled independently, scaling capacity without proportionally increasing processing complexity.
