摘要： A network packet capturing method for capturing a plurality of packets from a physical layer to an application layer by a network server through a network card is described. The packet capturing method includes the following steps. Capture packets by a new application interface (NAPI); set a ring queue in a kernel; provide a hook process for capturing the packets; store the captured packets into the ring queue; and map the packets stored in the ring queue into a memory space of a corresponding application through memory mapping, thereby reducing the number of interrupts of the system and the number of replications during the packets parsing.

摘要： A method for processing data packet load balancing and a network equipment thereof, which are for balancing the load of a plurality of controllers in a network equipment. The method comprises the steps. A plurality of data packets is received. A storage queue is assigned for storing the data packets. The data packets in the storage queue are read by an allocation controller. The allocation controller assigns the data packets to different work sequences according to a work attribute of the data packets. A processing controller is commanded to perform a packet processing procedure, and at least one work queue is assigned to the processing controller for processing the data packets. After completing the packet processing procedure, the processing controller sends a completion message to a completion queue. If the allocation controller detects that the completion queue contains the completion message, the allocation controller sends the processed data packets back.
