Code Block Stream Multiplexing to Reduce Network Cross-Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current end-to-end networking technologies, such as X-Ethernet, lack consideration for hierarchical multiplexing, leading to difficulties in managing and maintaining large-scale networks with numerous cross-connections, which puts pressure on intermediate nodes and complicates network operations.
Innovation Solution
A data transmission method that multiplexes and demultiplexes code block streams based on code block granularity, allowing them to traverse intermediate nodes without being demultiplexed, thereby reducing the number of cross-connections and operational pressures by using code block streams with specific coding types and placing bits corresponding to code blocks in payload areas of second code block streams.

Engineering Contradiction Analysis
1Productivity
If end-to-end networking technologies (such as X-Ethernet) are used without hierarchical multiplexing, then data transmission can be achieved, but network management and maintenance become difficult in large-scale networks with numerous cross-connections
Solution Approach 1:
The patent segments the data transmission process into distinct multiplexing and demultiplexing stages. Intermediate nodes perform only multiplexing (combining multiple code block streams) without demultiplexing, while terminal nodes perform demultiplexing. This segmentation reduces the operational burden on intermediate nodes and simplifies network management.
Solution Approach 2:
The patent introduces code block streams as intermediary carriers that traverse intermediate nodes without requiring demultiplexing. These intermediary streams allow data to pass through the network efficiently while minimizing the complexity of operations at intermediate nodes, thereby improving ease of management.
2Adaptability or versatility
If code block streams are demultiplexed at every intermediate node, then data can be routed flexibly, but the burden on intermediate nodes increases significantly
Solution Approach 1:
The patent divides the network into terminal nodes and intermediate nodes with distinct functions. Terminal nodes perform demultiplexing operations, while intermediate nodes perform only multiplexing. This functional segmentation maintains routing flexibility at terminals while reducing intermediate node complexity.
Solution Approach 2:
The patent applies partial demultiplexing action only at terminal nodes rather than at every node. Intermediate nodes perform partial action (multiplexing only) without full demultiplexing, which reduces their complexity while still enabling flexible routing through the network architecture.
