Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies cannot upgrade the time synchronization profile in networks from older profiles like the default or g.8265.1 profile to newer profiles like g.8275.1 or g.8275.2 without changing hardware or software, restricting the functionality of new hardware devices added to the network.
Innovation Solution
A synchronization device and method that synchronizes nodes supporting different time protocol profiles by using a counter, time protocol stack circuits, and a servo circuit to calculate and correct system operating time and clock signals, allowing communication across different protocol profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network adopts an older time synchronization profile (e.g., default profile or g.8265.1 profile), then existing hardware and software can maintain compatibility, but new hardware devices cannot upgrade to newer profiles (e.g., g.8275.1 or g.8275.2 profile) without changing hardware or software
Solution Approach 1:
The synchronization device acts as an intermediary between nodes using different time synchronization profiles. It translates messages between older profiles (default, g.8265.1) and newer profiles (g.8275.1, g.8275.2), enabling protocol profile upgrades without requiring changes to existing hardware or software. The device includes multiple time protocol stack circuits that handle different profile types and a translation mechanism that converts messages across profile boundaries.
2Adaptability or versatility
If new hardware devices are added to the network, then network functionality is enhanced, but the devices are restricted to using older profiles, limiting their full functionality
Solution Approach 1:
The synchronization device enables new hardware devices to access advanced synchronization features by acting as a mediator. Devices using newer profiles (g.8275.1, g.8275.2) can communicate with the synchronization device, which translates their messages to compatible formats with older network nodes, thereby unlocking full device functionality without compromising network compatibility.
Solution Approach 2:
The synchronization device is designed with multi-functionality to support multiple time synchronization profiles simultaneously. It includes a counter for system operating time, multiple time protocol stack circuits for different profiles, and a servo circuit for calculating time delays and frequency drifts. This universal design allows the device to serve both legacy and modern protocols within the same network infrastructure.
3Adaptability or versatility
If the synchronization device supports multiple time protocol profiles, then protocol compatibility is improved, but the device complexity increases
Solution Approach 1:
The synchronization device is segmented into distinct functional modules: a counter for system operating time, multiple time protocol stack circuits for different profiles (each handling specific profile logic), a servo circuit for time delay and frequency drift calculations, and a translation mechanism. This segmentation allows each module to specialize in a specific protocol or function, making the overall complex system more manageable and maintainable while supporting multiple profiles.

AI summary
A synchronization device and a synchronization method for synchronizing a first node and a second node are provided. The first node supports a first time protocol profile, and the second node supports a second time protocol profile. The synchronization method includes: providing a system operating time by a counter; communicating with the first node based on the first time protocol profile to obtain first synchronization information; calculating a time delay according to the first synchronization information, and correcting the system operating time according to the time delay to generate a corrected system operating time; and communicating with the second node based on the second time protocol profile so as to provide the second node with second synchronization information according to the corrected system operating time.
