Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Clos topology is used to support expansion of data centers, then network capacity and connectivity are improved, but the number of spine switches and intermediate switching layers increases, leading to increased device complexity and power consumption
Solution Approach 1:
The patent merges multiple switching functions into a single layer of routing devices. Instead of having separate spine switches and intermediate switching layers as in Clos topology, the invention uses a single layer of routing devices that perform both switching and routing functions, thereby reducing device complexity while maintaining network capacity through harmonic connections and multipath routing
Solution Approach 2:
The routing devices in the single layer network perform multiple functions simultaneously - they act as both switches and routers, and can dynamically adjust bandwidth allocation across multiple paths. This multi-functionality eliminates the need for specialized spine switches and intermediate layers, reducing overall device complexity while maintaining adaptability
2Adaptability or versatility
If Clos topology is used to support expansion of data centers, then network capacity and connectivity are improved, but power consumption increases due to additional active network devices
Solution Approach 1:
By merging switching and routing functions into a single layer, the patent reduces the total number of active network devices. Fewer devices mean lower aggregate power consumption while network capacity is maintained through the harmonic connection architecture that enables efficient multipath routing
Solution Approach 2:
The patent replaces the mechanical addition of more switching layers with an optical-based solution using harmonic connections and multipath routing. This substitution allows the system to scale network capacity without proportionally increasing the number of power-consuming physical devices
3Device complexity
If single layer network is used, then device complexity and power consumption are reduced, but achieving linear scalability with low hop counts requires innovative connection patterns
Solution Approach 1:
The patent segments the network connections into harmonic patterns that systematically organize how routing devices connect to each other. This segmentation into predictable connection patterns enables linear scalability while maintaining low hop counts, as each new device can be integrated following the established harmonic pattern without increasing overall complexity
Solution Approach 2:
The patent implements dynamic bandwidth allocation that allows the network to adapt to changing traffic demands in real-time. This dynamic capability enables the single layer network to scale efficiently by optimally utilizing available paths, maintaining productivity as the network grows

AI summary
A computer network organized in a logical grid having rows and columns can include network nodes coupled according to harmonics. Each network node can be coupled to network nodes of the same row using a set of horizontal strands according to a set of horizontal harmonics. Each of the horizontal harmonics specifies a node distance along the row between adjacent connection points on the corresponding horizontal strand. Each network node can also be coupled to network nodes of the same column using a set of vertical strands according to a set of vertical harmonics. Each of the vertical harmonics specifies a node distance along the column between adjacent connection points on the corresponding vertical strand.
