Dynamic Network Coding in Multiple-Link Communication Networks

The patent implements dynamic network coding by allowing coding parameters (such as coding rate, symbol size, and link selection) to change adaptively based on current link conditions. The system continuously monitors link quality metrics and adjusts coding parameters in real-time, transforming the static configuration into a dynamic one that responds to changing network conditions while maintaining manageable complexity through automated control algorithms.

The patent employs feedback mechanisms where the system continuously monitors link quality metrics (such as packet loss rates, transmission errors, and link availability) and uses this information to dynamically adjust coding parameters. The feedback loop enables the system to optimize transmission efficiency by adapting coding rates and link selections based on real-time network conditions, thereby resolving the contradiction between straightforward implementation and transmission efficiency.

The patent implements self-service mechanisms where the network coding system automatically monitors its own performance, detects link condition changes, and adjusts coding parameters without external intervention. The system includes built-in monitoring components that track link quality and automated control logic that modifies coding parameters based on detected conditions, enabling the system to improve transmission efficiency while managing complexity through self-management rather than external control.

The patent extends random linear network coding by introducing variable coding parameters that can be adjusted based on link configurations. While maintaining the core simplicity of random linear coding for generation and encoding, the system allows parameters such as coding rate, symbol size, and link selection probabilities to be dynamically modified according to specific link conditions, thereby achieving both implementation efficiency and adaptability to different link configurations.
