1Quantity of substance
If compression or right-sizing content is used, then data size is reduced, but network volatility and diversity still impact transport performance
Solution Approach 1:
The system performs preliminary actions by collecting historical network traffic data and training machine learning models before actual data delivery. The models are pre-trained to predict network conditions and optimize TCP parameters, enabling proactive adaptation rather than reactive responses to network changes.
Solution Approach 2:
The patent creates a virtual copy of the wireless network environment using probabilistic models trained on historical data. This simulated network environment allows testing and optimization of TCP parameters without requiring real-time network traffic, enabling reliable performance prediction across diverse network conditions.
2Productivity
If TCP parameters are optimized for specific network conditions, then performance improves, but network diversity makes single parameter optimization insufficient
Solution Approach 1:
The patent develops a universal machine learning model that handles multiple network conditions and TCP parameter optimizations simultaneously. The model is trained on diverse historical network data representing various wireless networks, devices, and protocols, enabling it to adapt to new network conditions without retraining and provide comprehensive coverage across different scenarios.
Solution Approach 2:
The system dynamically changes TCP parameters based on predicted network conditions. Instead of fixing parameters for specific conditions, the machine learning model continuously adjusts multiple TCP parameters (such as window size, timeout values, and congestion control settings) to optimize performance across the full spectrum of network diversity.
3Measurement precision
If real network traffic data is used for testing, then performance metrics are accurate, but network volatility makes consistent testing difficult
Solution Approach 1:
The patent creates a stable copy of network conditions through probabilistic models trained on historical traffic data. These models generate synthetic network environments that replicate real-world volatility and diversity characteristics, enabling consistent testing while maintaining measurement accuracy through faithful reproduction of network behavior patterns.
Solution Approach 2:
The system performs preliminary training on extensive historical network data to establish baseline performance metrics and network behavior patterns before conducting tests. This pre-processing creates a stable reference framework that allows accurate measurement of performance improvements while accounting for inherent network volatility.
4Productivity
If network optimization is performed in real-time, then performance adapts to current conditions, but computational resources and complexity increase
Solution Approach 1:
The patent performs computationally intensive tasks in advance by training machine learning models on historical network data before deployment. The trained models are then deployed to edge devices where they perform lightweight inference to optimize TCP parameters in real-time, significantly reducing computational complexity during actual data delivery while maintaining adaptive performance.
Solution Approach 2:
The system replaces complex real-time network analysis and optimization mechanisms with pre-trained machine learning models. Instead of performing sophisticated network monitoring and parameter tuning computations during data delivery, the system uses the trained models to directly predict optimal TCP parameters, substituting heavy computational mechanics with efficient predictive inference.
