Abstract
A network interface system with packet filtering function is disclosed herein. The network interface system includes interfaces, a packet buffer and a controller. The packet buffer stores data packets received by the network interface system. The controller provides security defense for the host system and the network by filtering the data packets stored in the packet buffer. The controller controls the packet buffer abandoning a data packet if the data packet is identified as an unsafe packet. The controller also includes a regulator for controlling a transferring order of the data packets. Thus, the network interface system can drop unsafe data packet and transfer data packets considered as safe information. The data packets can be processed in a sequence according to preset priority rules.
