Problems solved by technology

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 quickly. When users need to add / delete / modify filtering policies, the efficiency lower

Abstract

The invention provides a filtering strategy management system and method. The filtering strategies in the hardware memory and the filtering strategies in the software memory are in one-to-one correspondence, the filtering strategies are managed by a user through the software (the second storage module), the change is synchronized to the hardware when the filtering strategies are changed, and high-speed matching of messages is realized through the hardware (the first storage module). The system and method are oriented to users at a software level and used for managing a strategy and are oriented to network flows at a hardware layer, and high-speed matching of messages is realized. Through close connection between software and hardware, an 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...
