Solution Overview

Problem

The increasing complexity and scale of data center networks require efficient methods to connect numerous switches and devices, leading to a high likelihood of cabling errors and significant costs due to the large number of connections needed, especially in high-radix network topologies.

Innovation Solution

The use of a network transpose box that implements a selected meshing or network topology, reducing the number of cables and connections required by handling full meshing internally, and incorporating keying approaches to prevent errors, such as color coding and unique connectors, to facilitate deployment, maintenance, and scaling of networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a large number of direct connections are made between network switches to achieve full mesh topology, then network redundancy and connectivity are improved, but the number of cables and connection complexity increase significantly

Engineering Contradiction:
Improvenetwork redundancyVSAvoidcabling complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a transpose box as an intermediary device that consolidates multiple cable connections. Instead of directly connecting each switch to every other switch (requiring N×(N-1)/2 cables), all switches connect to the transpose box, which internally performs the full mesh connectivity. This mediator reduces the physical cabling from quadratic to linear complexity while maintaining full network redundancy.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The transpose box merges multiple individual cable connections into a single consolidated unit. Multiple cables from different switches are bundled together and connected to the transpose box, which then distributes them according to the required mesh topology. This combining approach simplifies installation and maintenance by reducing the number of separate connection points.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If the number of network connections is increased to accommodate more customers and resources, then network capacity and available resources are improved, but the likelihood of cabling errors increases

Engineering Contradiction:
Improvenetwork capacityVSAvoidcabling accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The transpose box serves as a centralized intermediary that manages all cable connections. Instead of making numerous individual connections between switches (each prone to error), all connections terminate at the transpose box, which has pre-configured internal wiring. This single point of control dramatically reduces installation errors and simplifies troubleshooting.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The transpose box is pre-configured with the correct internal cable mappings before deployment. The full mesh topology is established in advance within the box, so when switches are connected to it, the correct connectivity is automatically provided without requiring complex on-site configuration or calibration.

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If traditional cabling architectures are used to connect network devices, then initial deployment is achieved, but future scaling and technology evolution require early replacement of cabling infrastructure

Engineering Contradiction:
Improvedeployment feasibilityVSAvoidfuture scalability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent separates the cabling infrastructure into two independent segments: the physical cable layer and the logical connectivity layer. The cables themselves remain simple point-to-point connections, while the complex mesh topology is implemented in the transpose box. This segmentation allows the cable infrastructure to remain unchanged while the transpose box can be reconfigured or upgraded to support new topologies and technologies.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The transpose box provides dynamic reconfigurability through software control, allowing the network topology to be changed without physical cable modifications. The box can be reprogrammed to implement different mesh patterns, accommodate new switches, or adapt to evolving network requirements, making the infrastructure future-proof while maintaining simple static cabling.

Inventive Principle:
Principle #15Dynamics

AI summary

The deployment and scaling of a network of electronic devices can be improved by utilizing one or more network transpose boxes. Each transpose box can include a number of connectors and a meshing useful for implementing a specific network topology. When connecting devices of different tiers in the network, each device need only be connected to at least one of the connectors on the transpose box. One or more of the deployed electronic devices (e.g., switches, transpose boxes) in the network can transmit data based on a backplane Ethernet standard, such as 10GBASE-KR, 10GBASE-KX4, or 40GBASE-KR4.
