Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication networks often suffer from insufficient bandwidth, poor quality of service, latency, and data throughput issues due to their single-channel design, which limits their ability to handle high-speed and high-capacity data transmissions effectively.
Innovation Solution
A traffic splitting transmission (TST) system that splits data flows into multiple sub-flows and transmits them over multiple communication links, utilizing a core node with components like a receiver, link selector, split unit, tag module, encapsulate module, and delay module to manage and optimize the transmission process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single communication channel is used, then the network infrastructure is simple, but the bandwidth and data throughput are insufficient
Solution Approach 1:
The patent divides a single data flow into multiple sub-flows and transmits them through different communication channels simultaneously. The data flow is segmented at the source device, routed through multiple paths, and reassembled at the destination, effectively multiplying the available bandwidth without requiring a single high-capacity channel.
Solution Approach 2:
The patent transitions from single-channel transmission to multi-channel parallel transmission by adding the dimension of multiple communication paths. This dimensional expansion allows simultaneous data transmission across multiple links, increasing overall throughput while maintaining infrastructure simplicity through software-based flow management.
2Reliability
If a single communication channel is used, then the network configuration is simple, but the quality of service and latency performance are poor
Solution Approach 1:
The patent segments the data flow into multiple sub-flows that can be transmitted simultaneously over different channels with varying characteristics. This segmentation allows optimization of different sub-flows according to channel conditions, improving overall quality of service through diverse transmission paths.
Solution Approach 2:
The patent dynamically adjusts transmission parameters such as routing paths, modulation schemes, and power allocation across multiple channels based on real-time channel conditions. This parameter optimization enables adaptive quality of service management, reducing latency and improving reliability through intelligent resource allocation.
3Productivity
If data is transmitted over multiple communication links, then bandwidth utilization improves, but packet ordering and synchronization become complex
Solution Approach 1:
The patent introduces intermediary devices (routers, switches, and processing units) that manage packet routing, tracking, and reassembly across multiple channels. These intermediaries maintain packet sequence information and coordinate transmission timing, simplifying the complexity of multi-channel packet management through dedicated control functions.
Solution Approach 2:
The patent replaces complex mechanical synchronization mechanisms with software-based packet tagging, sequencing, and virtualization techniques. By using protocol headers, sequence numbers, and buffer management algorithms, the system achieves efficient packet ordering without requiring precise hardware synchronization across multiple channels.
Data Source
AI summary
A traffic split transmission (“TST”) system capable of transmitting a data flow via multiple communication networks is disclosed. The TST system, in one aspect, includes a receiver, a link selector, a split unit, a tag module, and a delay module. The receiver obtains a data flow containing one or more packets with a destination at a user terminal (“UT”). The link selector fetches link characteristics associated with the current status of available links. The split unit splits the data flow into a first and a second packets. The tag module generates tags for the first and the second packets. The delay module is configured to delay transmission of a selected packet(s) so that the first packet and the second packet can arrive at UT at approximately the same time.
