According to one embodiment, a set of DCA control settings are defined by a network interface controller (NIC) of a network security device for each of multiple I/O device queues. The control settings specify portions of network packets that are to be copied to a cache of the corresponding CPU. A packet is received by the NIC. The packet is parsed to identify boundaries of portions of the packet and is queued onto an I/O device queue. The packet is then transferred from the I/O device queue to a host memory of the network security device and the specified portions are concurrently copied to the cache of the corresponding CPU based on the control setting associated with the I/O device queue."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Direct cache access for network input/output devices","description":"Methods and systems for improving efficiency of direct cache access (DCA) are provided.
