摘要：
In order to maintain the security of optical network, it is urgent to research and deploy photonic firewall which can effectively process high-speed optical signals to replace existing electronic firewall which consumes high energy. After a brief review of the principle of photonic firewall, the pattern matching technology based on correlation operation and all-optical logic gates were summarized, and the matching systems was compared according to their advantages and disadvantages. Besides, the realization methods of all-optical logic gates were introduced. Finally, the next research direction and development trend of all-optical pattern matching were prospected: more efficient system structure or non-linear devices with faster response speed. The survey shows that photonic firewall based on all-optical pattern matching has a good application prospect in network security. © 2019, Editorial Board of Journal on Communications.
