Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-capacity wide-coverage networks face performance degradation due to multi-hop packet-switching, where paths from source to destination traverse numerous routing nodes, leading to structural complexity and increased costs. Simplifying network structure and reducing diameter is desirable to improve performance and facilitate broadband services.
Innovation Solution
A latent space switch employing a single transposing rotator with N inlets and outlets, configured to cyclically connect each inlet to each outlet during a time frame organized into N time slots, utilizing memory devices and port controllers to manage data transfer and control messages efficiently, ensuring concurrent data transfer and read operations.

Engineering Contradiction Analysis
1Area of stationary object
If multi-hop packet-switching networks are used to achieve wide coverage, then network coverage area increases, but network diameter and performance degradation increase
Solution Approach 1:
The patent transitions from traditional spatial network topology to a latent space dimension. By mapping network nodes to points in a latent space and using geometric relationships (distance, angles) in this abstract dimension, the system achieves wide coverage with reduced effective diameter. Nodes that are geometrically close in latent space can communicate efficiently even if physically distant in the traditional network topology.
Solution Approach 2:
The patent introduces latent space coordinates as an intermediary layer between physical network nodes and communication paths. Instead of direct multi-hop routing through intermediate routers, nodes use their latent space positions to determine optimal communication paths, reducing the number of intermediate nodes traversed and improving overall network performance.
2Area of stationary object
If multiple routing nodes are used to achieve wide coverage, then network coverage increases, but performance degradation increases
Solution Approach 1:
By operating in latent space rather than physical network topology, the system can find shorter effective paths between nodes. The latent space geometry allows direct routing based on coordinate differences, reducing the number of hops and intermediate nodes, thereby maintaining high performance across wide coverage areas.
Solution Approach 2:
The patent creates a virtual copy of the network in latent space, where geometric relationships replace complex routing logic. This latent space representation allows efficient calculation of communication paths without traversing multiple physical routing nodes, thus maintaining performance while achieving wide coverage.
3Device complexity
If traditional switching nodes are used to simplify network structure, then device complexity reduces, but network diameter remains large
Solution Approach 1:
The patent applies latent space transformation to simplify network structure while reducing diameter. By representing nodes in a low-dimensional latent space and using geometric operations (vector addition, normalization) to determine routing, the system achieves both structural simplicity and reduced effective diameter, overcoming the limitation of traditional switching nodes.

AI summary
A single transposing rotator successively connects a set of access ports to a set of memory devices and the set of memory devices to the set of access ports. A set of inlet selectors connecting to rotator inlets and a set of outlet selectors connecting to rotator outlets are coordinated to concurrently connect the access ports to the memory devices through the rotator, and concurrently connect the memory devices to the access ports. Each memory device connects to an inlet selector and a corresponding peer outlet selector. Multiple temporal multiplexers submit upstream control messages from the access ports to a multi-port master controller. Multiple temporal demultiplexers distribute downstream control messages sent from the master controller to the access ports. Alternatively, the multi-port master controller may connect to selected inlet selectors and corresponding peer outlet selectors for successively receiving upstream control messages and sending downstream control messages.
