Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed bandwidth optical fiber is used for transmission, then transmission stability is ensured, but flexibility in bandwidth adjustment is lost
Solution Approach 1:
The patent segments the optical interface into multiple logical interfaces, each with configurable bandwidth parameters. This allows the physical optical fiber to be divided into multiple virtual channels with different bandwidth allocations, enabling flexible bandwidth adjustment without changing the physical infrastructure. The segmentation resolves the contradiction by providing adaptability through logical division while maintaining the stability of the physical connection.
Solution Approach 2:
The patent implements dynamic bandwidth allocation by allowing the line card to adjust the bandwidth parameters of logical interfaces in real-time based on network demands. The correspondence relationships between optical serial signal flows and logical interfaces can be dynamically modified, enabling the system to adapt to changing traffic patterns while maintaining stable physical connections.
2Adaptability or versatility
If multiple optical interfaces are configured for different bandwidths, then flexible Ethernet support is improved, but device complexity increases
Solution Approach 1:
The patent makes a single physical optical interface serve multiple functions by creating multiple logical interfaces from it. Each logical interface can be configured with different bandwidth parameters to support various Ethernet standards (1G, 10G, 25G, etc.), allowing one physical interface to replace what would traditionally require multiple physical interfaces. This reduces device complexity while maintaining flexible Ethernet support.
Solution Approach 2:
The patent introduces logical interfaces as an intermediary layer between the physical optical interface and the optical serial signal flows. This intermediary abstraction layer simplifies management by providing a standardized interface for configuring bandwidth and mapping signal flows, reducing the complexity of managing multiple physical interfaces with different characteristics.
3Productivity
If bandwidth of logical interface is dynamically modified, then network efficiency is improved, but processing complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the line card monitors network traffic conditions and automatically adjusts the bandwidth parameters of logical interfaces based on actual usage patterns. This feedback-driven approach optimizes network efficiency by allocating bandwidth dynamically according to real-time demands, while the automated nature of the adjustment reduces the processing complexity compared to manual configuration.
Solution Approach 2:
The patent enables dynamic modification of bandwidth parameters for logical interfaces without changing the physical infrastructure. By allowing flexible adjustment of logical parameters (bandwidth allocation, signal flow mapping) while keeping physical connections stable, the system achieves improved network efficiency with minimal increase in processing complexity, as the changes are confined to the logical configuration layer.
