Abstract

The present application provides a filtering policy management system and method thereof. Corresponding the filtering strategy in the hardware memory with the filtering strategy in the software memory one by one, realize the user's management of the filtering strategy through the software (second storage module), and synchronize the change to the hardware when the filtering strategy changes, The high-speed matching of the message is realized by hardware (the first storage module). At the software level, it faces users and manages policies; at the hardware level, it faces network traffic and realizes high-speed packet matching. Through the close connection between software and hardware, efficient message filtering function is realized.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a filtering policy management system and method thereof. Background technique [0002] The principle of the filtering policy is to check the packet headers of the packets passing through the firewall packet by packet, and perform corresponding policy operations on the packets that meet the filtering conditions. First obtain the information of the packet header, such as the source IP address, destination IP address, protocol number of the upper layer protocol carried by the IP layer, source port number, destination port number, etc., when the packet header is successfully matched, execute the Forwarding, discarding and other operations. [0003] Filtering policies essentially classify packets. In general, storing filtering policies in hardware such as DDR can quickly perform packet matching, but the hardware side cannot respond to user needs efficiently and quickl...
