[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] like figure 1 As shown, a network detection method for an intelligent network card, the intelligent network card stores ACL rules, and the network detection method includes the following steps:
[0025] A. Use the network card management module to deliver the five-tuple ACL rules on the server side to the smart network card storage module;
[0026] B. The smart network card receives network data, and performs IP fragmentation reorganization and TCP stream reorganization on the received data;
[0027] C. In the data processing module of the smart network card, the received packets are matched with the existing ACL rules in the storage module, and corresponding actions of discarding, transparent transmission, tagging, sending packets or sending logs are taken;
[0028] If the discard action is adopted, the smart NIC ignores the packets with the dis...
