Method, processor and system for implementing network address conversion

Provided is a method for realizing the network address conversion, a processor and a system, wherein the method includes: performing the NAT operation recognition on the received message, selecting the corresponding operation processor for treating the message NAT operation which is required to perform the NAT operation process between at least two NAT operation processors. According to the invention, the embodiment satisfies that a plurality of NAT operations are required to treat in a short time, capable of effectively advancing the NAT operation processing ability of the system.
