To realize the communication between IPv4 internet and IPv6 network by using a translation mechanism

this paper proposes a scheme for implementing NAT64 on data-communication products.On the basis of sufficient analysis of the operating principle of NAT64

this scheme strives to incorporate the existing hardware platform resources and software platform properties

thus reducing the usage of the system resources as much as possible

while ensuring the perfect implementation of the relevant functions.Test results show that the functional requirements of NAT64 are all realized and the operating performances are demonstrated as designed without any adverse effects on either equipment performance or network environment.
