Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional congestion control techniques adjust the data rate to avoid network saturation, then network congestion is reduced, but data quality degrades and redundancy is lost
Solution Approach 1:
The patent segments the single data stream into multiple parallel streams, each transmitted over a different network path. This allows the system to distribute data transmission across multiple routes, preventing any single path from becoming saturated while maintaining overall data quality and redundancy through diverse transmission channels.
Solution Approach 2:
The patent transitions from a single-dimensional transmission approach (one path) to a multi-dimensional approach (multiple paths). By adding the dimension of path diversity, the system can simultaneously achieve congestion avoidance on individual paths while maintaining data quality and redundancy through the collective capacity of multiple paths.
2Reliability
If multiple data paths are used for transmission, then data redundancy and reliability are improved, but network complexity increases
Solution Approach 1:
The patent implements self-service through automatic path selection and dynamic routing mechanisms. The system autonomously monitors network conditions, selects optimal paths for each data stream, and adjusts transmission parameters without manual intervention, thereby achieving high reliability through multiple paths while minimizing the operational complexity burden on users.
3Stability of the object's composition
If data rate is reduced to prevent network saturation, then network stability is maintained, but transmission timeliness deteriorates
Solution Approach 1:
The patent segments the data transmission load across multiple parallel paths, allowing each path to operate at stable rates without saturation while collectively achieving high transmission throughput. This segmentation enables timely delivery of data packets through multiple concurrent streams without compromising individual path stability.
Solution Approach 2:
The patent dynamically changes transmission parameters such as path selection, data rate allocation, and routing decisions based on real-time network conditions. By adjusting these parameters adaptively, the system maintains network stability on each path while ensuring timely overall transmission through optimized resource allocation across multiple paths.

AI summary
Described are systems and methods for determining one or more data paths of a network link for transmitting data packets of a data stream for load balancing the data across the paths while avoiding saturation of the network link and/or alleviating congestion of the network link. The selection of the one or more paths may be performed by adaptively modifying a redundancy of the data packets being transmitted on the transmission paths of the network link in view of current network parameters associated with the paths of the network link, so that the data stream is effectively load balanced across the paths of the network link while ensuring redundancy of the data stream and maintaining the data rate of the data stream.
