Network Synchronization Accuracy via Intermediate Node Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional synchronization methods in networks often result in poor synchronization effects due to the selection of synchronization signals based solely on synchronization source information, leading to the choice of signals with larger time errors.
Innovation Solution
Intermediate nodes update the synchronization information with their own accuracy data, allowing nodes to synchronize using signals with the minimum current time error, thereby improving synchronization accuracy.

1Device complexity
If nodes select synchronization signals based solely on synchronization source information, then the selection process is simple, but the synchronization accuracy deteriorates due to selecting signals with larger time errors
Solution Approach 1:
The synchronization information is segmented into multiple components: synchronization source information and intermediate node information. Each intermediate node on the transmission path adds its own accuracy information to the synchronization packet, creating a hierarchical structure that allows receiving nodes to evaluate the entire path quality, not just the source quality.
Solution Approach 2:
Intermediate nodes perform preliminary evaluation of their own synchronization accuracy and embed this information into the synchronization packets before forwarding them. This preliminary action allows receiving nodes to make informed selection decisions without having to perform complex path analysis themselves.
2Measurement precision
If intermediate nodes add their accuracy information to synchronization packets, then synchronization accuracy improves, but the information processing complexity increases
Solution Approach 1:
The patent extracts only the essential accuracy information from each intermediate node and embeds it into the synchronization packet. Rather than transmitting complete node profiles or complex path data, only the critical accuracy metrics are extracted and included, minimizing the additional processing burden.
Solution Approach 2:
Each intermediate node autonomously evaluates its own synchronization accuracy and adds this information to the packets it forwards. This self-service approach eliminates the need for centralized control or complex coordination mechanisms, as each node independently contributes to the overall synchronization information.
3Ease of operation
If nodes use only synchronization source information for selection, then the selection mechanism is simple, but the time error increases leading to poor synchronization effect
Solution Approach 1:
The intermediate node information acts as an intermediary element between the synchronization source and the receiving node. This intermediary information provides a bridge that allows receiving nodes to evaluate the quality of the entire transmission path without directly interacting with each intermediate node, maintaining operational simplicity while reducing time error.
