CPE Uplink Latency Control Through Adaptive Packet Queuing

The patent implements dynamic buffer size adjustment by introducing a buffer size adaptation module that continuously monitors network conditions and adjusts the buffer size accordingly. The buffer size is dynamically changed based on measured round-trip time (RTT) and throughput metrics, transitioning from a static to a dynamic buffering strategy that adapts to changing network conditions to prevent bufferbloat while maintaining packet loss prevention.

The patent changes the buffer size parameter from a fixed value to a dynamically adjusted parameter. The buffer size adaptation module modifies the buffer size parameter based on network performance metrics such as RTT and throughput, allowing the system to optimize the trade-off between packet loss prevention and latency reduction by adjusting this critical parameter in response to actual network conditions.

The patent implements a feedback mechanism where the buffer size adaptation module continuously monitors network performance metrics including round-trip time (RTT) and throughput. This feedback loop allows the system to detect when latency is increasing due to bufferbloat and automatically adjust the buffer size downward, or when packet loss is occurring and increase the buffer size, creating a self-regulating system that balances reliability and latency.

The system transitions from static buffer allocation to dynamic buffer adjustment, where the buffer size is continuously adapted based on real-time network conditions. This dynamic approach allows the CPE to respond to burst traffic patterns by temporarily increasing buffer capacity while automatically reducing buffer size when conditions improve, thereby preventing sustained bufferbloat and its associated latency penalties.
