The invention discloses a data packet processing method and device. A data packet is received; each type of data in the data packet are cached to the corresponding data line of a cache address line; existence of a target address line is judged, and the data of each data line of the target address line is the same with the data on the corresponding data line of the cache address line; if the judgment result is yes, the data packet is processed according to the preset rules corresponding to the target address line; and if the judgment result is no, the data packet is processed according to the default rules. Therefore, the rules of the data can be defined on the target address line by the data packet processing method, the data in the data packet are put on the corresponding data line of the address line to be matched with the target address line when the data packet is received, and the processing mode of one data packet can be quickly decided through parallel matching of the hardware mode so that the processing time of the data packet can be reduced and the access speed can be improved.
Description
technical field [0001] The present invention relates to the field of network security, and more specifically, to a method and device for processing data packets. Background technique [0002] With the rapid development of network technology, while the network brings convenience to people, it also brings threats. Many network virus attacks have brought huge losses to enterprises or individuals, so the security of network data is very important. [0003] Responding to network attacks can be achieved through access control, and the use of firewalls is a way of access control. Traditional firewalls mainly establish access rules during access control, and match each received data packet with access rules one by one until the last one. If the corresponding rule is matched, it will be processed according to the rule, and if it is not matched, it will be processed according to the default rule. [0004] When there are many access rules established, matching the access rules one b...
