Bonded MoCA LDPC Parameter Management for Dual-Channel Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coordinating hardware for parallel communication over multiple channels in home entertainment networks, such as those following the MoCA standard, is cumbersome and complex due to the need for independent calculation of LDPC forward error correction code parameters and padding bits by both transmitter and receiver nodes.
Innovation Solution
A method and apparatus for low-density parity check (LDPC) transmission over a bonded channel system, where data is divided into segments for the primary and secondary channels, with optimized forward error correction parameters and padding calculations to facilitate easy coordination and efficient data transmission across interconnected MoCA 2.0 SoCs.

Engineering Contradiction Analysis
1Productivity
If parallel communication over multiple channels is implemented to increase information transmission capacity, then productivity is improved, but device complexity increases due to the need for independent calculation of LDPC parameters and padding bits by both transmitter and receiver nodes
Solution Approach 1:
The patent introduces a channel bonding manager as an intermediary component that centralizes the calculation and management of LDPC parameters and padding bits. Instead of requiring both transmitter and receiver nodes to independently calculate these parameters, the channel bonding manager acts as a mediator that determines the bonding parameters and provides them to the appropriate nodes, thereby reducing the computational burden and coordination complexity while enabling parallel communication over multiple channels
2Ease of operation
If coordination mechanisms are added to manage multiple bonded channels, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The channel bonding manager implements self-service mechanisms by automatically monitoring channel conditions, dynamically adjusting bonding parameters, and managing the coordination between multiple channels without requiring manual intervention or complex external control systems. The manager autonomously performs calculations for LDPC parameters and padding bits based on real-time channel state information, thereby improving ease of operation while keeping the added complexity contained within a single management component rather than distributing it across multiple nodes

AI summary
A particular overall architecture for transmission over a bonded channel system consisting of two interconnected MoCA (Multimedia over Coax Alliance) 2.0 SoCs (Systems on a Chip) and a method and apparatus for the case of a “bonded” channel network. With a bonded channel network, the data is divided into two segments, the first of which is transported over a primary channel and the second of which is transported over a secondary channel.
