Synchronous Network Frame Counter Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Synchronous networks face challenges in maintaining synchronization, leading to frame loss during maintenance or when errors occur, which affects network robustness and requires time-consuming re-synchronization.
Innovation Solution
A system that matches frame counter values between a timing master and slave devices in a synchronous network by counting transmitted frames, detecting synchronization losses, and transmitting a synchronization frame counter value to synchronize slave devices with the timing master, facilitating quick network resynchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network performs maintenance work or errors occur, then the synchronization requirements may be unfulfilled, but this causes frame loss and requires time-consuming re-synchronization
Solution Approach 1:
The system transmits synchronization information continuously in advance, so that when maintenance work or errors occur, the slave devices already have the necessary synchronization data to quickly recover without requiring time-consuming re-synchronization procedures
Solution Approach 2:
The timing master continuously transmits synchronization frame counter values to slave devices, creating a feedback mechanism that allows rapid detection and correction of synchronization losses, minimizing the time required to restore synchronization after disruptions
2Adaptability or versatility
If a slave device is added to the network, then network functionality is enhanced, but synchronization losses occur
Solution Approach 1:
The continuous transmission of synchronization frame counter values from the timing master to slave devices creates a real-time feedback mechanism that automatically detects and corrects synchronization losses caused by adding new slave devices to the network
Solution Approach 2:
The system enables automatic self-synchronization of slave devices through continuous reception of synchronization information from the timing master, allowing the network to automatically adapt when new devices are added without manual re-synchronization intervention
Data Source
AI summary
A system matches frame counter values between a timing master and one or more slave devices in a synchronous network. To detect synchronization losses, a timing master counts transmitted frames of a continuous data stream. When a synchronization loss occurs, the timing master transmits a message to the slave devices that includes a synchronization frame counter value. The message synchronizes the frame counter value of the timing master to the frame counter value of the slave devices.
