System Design of Network Data classification Based on Deep Packet Inspection

With the rapid development of the Internet, as an important method of network security protection, network data classification has become the focus of high-tech research. In order to efficiently process massive network data, filter irrelevant data packets, and resist malicious attacks, so as to ensure the safety and stability of network operating, based on the research of deep packet inspection (DPI) technology, a kind of network data classification system has been presented. This system is based on the architecture of field-programmable gate array (FPGA) and ternary content addressable memory (TCAM). Tests show that the system can meet actual requirements of network data classification.
