Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual planning and deployment of clock synchronization paths is performed by network manager, then clock synchronization can be established, but deployment efficiency is low and error risk is high in large-scale networks
Solution Approach 1:
The system enables automatic determination of clock synchronization paths through the determination device that autonomously computes optimal paths based on network topology and clock synchronization requirements, eliminating manual intervention and its associated errors while maintaining high deployment accuracy
Solution Approach 2:
The manual mechanical process of path planning by network managers is replaced with an automated computational system that uses algorithms to determine clock synchronization paths, significantly improving both efficiency and accuracy in large-scale networks
2Reliability
If primary and secondary clock synchronization paths are deployed in advance, then clock synchronization is ensured, but when both paths are faulty, timely redeployment cannot be performed resulting in degraded clock precision
Solution Approach 1:
The determination device continuously monitors the status of clock synchronization paths and automatically triggers path determination when faults are detected, enabling timely recovery and maintaining clock precision without requiring manual intervention
Solution Approach 2:
The system transitions from static pre-deployed paths to dynamic path determination that adapts to real-time network conditions and failures, automatically computing new paths when faults occur to maintain synchronization reliability
3Productivity
If automatic path determination device is implemented, then deployment efficiency is improved and errors are reduced, but system complexity increases
Solution Approach 1:
The determination device performs multiple functions including path determination, status monitoring, and automatic recovery, consolidating what would otherwise require multiple separate systems into a single multi-functional component that improves efficiency without proportionally increasing complexity

AI summary
This application relates to the communications field, and in particular, to a method for updating a clock synchronization topology, a method for determining a clock synchronization path, and a device. The method includes: receiving a first packet from a first network element, where the first packet includes clock synchronization capability information of the first network element, the first network element is a network element in a first network, and the first network element has a clock synchronization capability; and updating a clock synchronization topology of the first network based on the clock synchronization capability information of the first network element. Further, the method further includes: determining a first clock synchronization path from a clock injection node of the first network to the first network element based on a request of the first network element and the clock synchronization topology of the first network. A clock synchronization topology is automatically updated based on clock synchronization capability information of a network element, and a clock synchronization path is determined, to reduce costs of deploying a clock synchronization path.
