  • Packet capture engine for commodity network interface cards in high-speed networks
    Patent number: 10079740
    Abstract: A method, systems for a packet capture engine for commodity network interface cards (NICs) in high-speed networks that provides lossless zero-copy packet capture and delivery services by exploiting multi-queue NICs and multicore architectures. The methods, systems include a ring-buffer-pool mechanism and a buddy-group based offloading mechanism.
