Latest Patents

One of his latest patents is titled "High-efficient packet I/O engine for commodity PC." This invention provides a method for implementing a packet I/O engine on a programmable computing platform, allowing the engine to perform I/O functions for multiple threads generated by various user applications. The method ensures that only one thread initializes and configures the resources, while I/O-device queues are established for buffering packets transmitted to or received from individual external I/O devices. Additionally, it sets up multi-producer, multi-consumer software queues to maintain data consistency in packet delivery amidst multiple threads.

Another significant patent is "PacketUsher: accelerating computer-intensive packet processing." This invention accelerates compute-intensive packet processing in a computer system by utilizing a packet I/O engine that allows direct access to a network interface card (NIC) from a user application. In a Linux-based system, standard I/O mechanisms are bypassed, and the packet I/O engine is employed for I/O functions. The system processes batches of packets in each function call and optimizes resource utilization by balancing workflows across different working threads.
