Development for the Diver of Smart NIC Based on Windows XP System

In order to further enhance the security of network data transmission, we put forward the design of the intelligent nic and the development of its driver in this paper. Intelligent nic uses FPGA chip to design and implement its main functions, and this chip has the built-in packet filter function which realizes the preliminary match and filter process to the network transmission data. Furthermore, we develop the driver that intelligence nic can use according to the system function, so as to further assure the safety of data transmission. The paper not only involves the design structure and work process of the intelligence nic, but also makes a detailed description of the realization of the main modules drivers. Finally, we analyze and confirm the availability of intelligence nic and its driver with packet capture tools.
