Abstract

The embodiment of the invention discloses a message matching system and method based on NFV. NFV network element equipment sends packaged rule data to a hardware accelerator. Wherein the rule data isa parameter on which message matching depends. The hardware accelerator receives the packaged rule data and stores the analyzed rule data to a preset position. When the hardware accelerator receives anetwork message, data information carried by the network message is analyzed; and the hardware accelerator receives the data information sent by the NFV network element device and queries target ruledata matched with the data information from a preset position, and the hardware accelerator can feed back the matched target rule data to the NFV network element device, so that the NFV network element device processes the network message according to the target rule data. The external hardware accelerator is introduced into an NFV system to realize an NAT function, so that the CPU load of NFV network element equipment is reduced, the message forwarding efficiency is improved, and the message forwarding time delay is shortened.

Description

technical field [0001] The invention relates to the technical field of network virtualization, in particular to an NFV-based message matching system and method. Background technique [0002] Network Function Virtualization (Network Function Virtualization, NFV) uses general-purpose hardware such as x86 servers, storage and switching devices based on industry standards, and virtualization technology to carry and run many existing network function software programs to replace those of the communication network. Private and dedicated network element equipment, thereby reducing the expensive equipment cost of traditional network hardware. [0003] Network Address Translation (NAT) will help slow down the depletion of available IP address space by using a small number of public IP addresses to represent a large number of private IP addresses. [0004] In the operation process of carrier-level NAT (CGN), NAT sessions are used for packet matching processing. The session data struc...
