Along with development of network techniques and firewall techniques, multi-pattern matching for content filtering, virus detection and other network security measures is emphasized in the field of hardware firewall. Principles of multi-pattern matching on network firewall based on FPGA (Field Programmable Gate Array) are presented: low latency, supporting non-fixed-length pattern and forward matching. And architecture of high-performance matching on data link layer forming pipeline with frame transmission is proposed especially for multi-port scheduling. By academic analysis and experimental validation it can support applications of high-performance hardware network firewall and effectively reduce additional delays by expand logics.
