Problems solved by technology
For the firewall, secondary traversal is very likely to cause problems such as network failure or service function failure.
Unrecognized for the same mac, it may cause network interruption, etc.
Comparing each data packet with the mac address will increase the performance of the loss device, increase the load of the device, and reduce the forwarding efficiency

The present application discloses a method and device for identifying a data packet, an electronic device and a computer-readable storage medium. The method includes: when receiving a target data packet, judging whether the target data packet is the first data packet of the session to which it belongs package; if so, then store the packet receiving network port of the target data packet and the security zone to which the packet receiving network port belongs to the record of the target session; if not, then store the packet receiving network port of the target data packet The network port and the security area to which the packet receiving network port belongs are compared with the record of the target session, and based on the comparison result, the data packet type of the target data packet is identified; wherein, the data packet type includes secondary penetration data packets and non-secondary penetration data packets. The data packet identification method disclosed in the present application improves the identification efficiency of the secondary traversal data packet.
Description
technical field [0001] The present application relates to the field of computer technology, and more specifically, to a data packet identification method and device, an electronic device, and a computer-readable storage medium. Background technique [0002] During operation and deployment of network devices such as firewalls, if the same packet passes through multiple times, it is called secondary traversal. For the firewall, secondary traversal is very likely to cause problems such as network failure or service function failure. [0003] In related technologies, it is determined whether the data packet has passed through the device multiple times by identifying the mac address of the data packet. Unrecognized for the same mac, it may cause network interruption and so on. Comparing each data packet with the mac address will increase the loss of device performance, increase the load of the device, and reduce the forwarding efficiency. [0004] Therefore, how to improve the...
