Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration is used for network synchronization in FlexE-based networks, then network devices can be configured to perform synchronization, but the operational complexity increases and synchronization efficiency decreases
Solution Approach 1:
The patent implements automatic configuration of network devices for synchronization by having the network device autonomously obtain synchronization mode indication and synchronization information, then automatically configure itself based on this information. This eliminates the need for manual configuration operations while maintaining proper synchronization setup, directly resolving the contradiction between ease of operation and device complexity.
2Productivity
If manual configuration is used for network synchronization, then synchronization can be achieved, but synchronization efficiency is reduced
Solution Approach 1:
The patent employs preliminary action by having the network device obtain synchronization mode indication and synchronization information in advance before actual synchronization operations are performed. This pre-configuring approach enables faster execution of synchronization tasks, thereby improving synchronization efficiency while reducing the complexity of the operation process.
3Extent of automation
If automatic configuration is implemented, then operation process is simplified and synchronization efficiency is improved, but additional signaling overhead is required
Solution Approach 1:
The patent achieves automatic configuration by utilizing existing FlexE overhead frames for multiple purposes - both for carrying synchronization mode indication and synchronization information, and for their original functions. This multi-functional use of existing signaling structures enables automation without requiring entirely new signaling mechanisms, thereby limiting the increase in signaling overhead while achieving the desired extent of automation.
