Abstract: A packet processing device is provided, which is applied to a network equipment that transmits packets. The device includes: a control module for executing a control schedule; a capture module for capturing at least one packet according to the control schedule; and a disassembling module for disassembling the header of the packet according to the control schedule so as to obtain packet header information. The packet processing device of the present invention can be installed in any network equipment to disassemble and process packets before they are captured by CPUs or memories of back-end computers, thereby achieving rapid processing of packets and reducing usage of CPU resources and occupancy of memories.
