Latest Patents

Yalun Li holds a patent for "Systems and methods for requesting packets for transmission over a wireless channel having a dynamically changing capacity due to a highly variable delay." This invention provides systems and methods that significantly reduce the under-utilization of high-speed radio channels. It features packet buffering and buffer management for specific link segments of end-to-end TCP connections. The dynamic rate control (DRC) mechanism transparently utilizes the advertised receiver window size within TCP to maintain a steady stream of packets over long and variable delay high-speed channels. The invention manages a queue by dynamically relating its current size to incoming data, adjusting the client advertised window size to predict buffer growth. DRC supplements TCP's end-to-end flow control, functioning as an agent hidden within the network.
