Latest Patents

Lixiang Liu's latest patents include a "Kind of congestion improvement method based on the QUIC protocol." This method enhances the QUIC protocol by incorporating round trip delay information into the congestion algorithm. It self-adaptively adjusts the value of α to assess the current network situation by comparing the last round trip time (RTT) with the current RTT. This allows for timely adjustments to the target window value, optimizing bandwidth utilization. The method addresses the limitation of the maximum congestion window of 200 in the QUIC protocol, which can hinder throughput in high bandwidth and long delay environments.

Another notable patent is the "Kind of transmission method based on the network learnable power model." This innovative approach records historical trends in network performance and applies weighted smoothing to round trip time. It establishes a model that correlates network power with the congestion control window. By updating the power model window upon receiving new acknowledgments (ACKs), this method forecasts the congestion control window size for future periods. It also incorporates traditional TCP retransmission mechanisms to handle packet loss or timeout events, thereby reducing the impact of random network events on estimation errors.
