NETWORK TRANSLATION REALIZATION METHOD AND APPARATUS FOR TRANSITING TO IPV6 ON THE BASIS OF PANT

摘要

Disclosed in the present invention are a network translation realization method and apparatus for transiting to IPv6 on the basis of PNAT. The method is applied to the network access apparatus CPE which is between a LAN side and a WAN side, and comprises the steps of: obtaining a message; performing a Prefix Network Address Translation (PNAT) on the message, and performing the corresponding uplink or downlink transmission on the translation result. With the present invention, the PNAT function is realized on the network access equipment CPE to achieve the transition to IPv6, and thus avoids the technical problems in prior art and solves the problems of the need to modify a great number of hosts and low feasibility which exist in the host apparatus modification solution in the prior art.
