Embodiment Construction

[0047]The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention .

[0048] refer to figure 1 , the embodiment of the present invention provides a method for implementing network transition based on PNAT to IPv6 transition, which is applied on the network access equipment CPE between the LAN side and the WAN side, and includes the following steps:

[0049] S10, obtaining a message;

[0050] S20. Perform prefix network address translation (PNAT) on the packet, and send the translation result correspondingly uplink or downlink.

[0051] In this embodiment, the method implements PNAT technology on the network access device CPE, and re-encapsulates and converts the IPv4 message provided by the IPv4 host on the LAN side ...

Abstract

The invention discloses a method and a device for realizing network translation to IPv6 Internet Protocol Version 6) based on PNAT (Prefix Network Address Translation) and a terminal device. The method is applied to CPE (Customer Premise Equipment) which is located between a LAN (Local Area Network) and a WAN (Wide Area Network) and comprises the steps of obtaining a message; and carrying out PNAT for the message, and carrying out corresponding uplink or downlink transmission for a translation result. According to the method, translation to the IPv6 is realized by realizing a PNAT function on the CPE, so that technical problems existing in the prior art are avoided, and the problems in the prior art that modification is required for a large number of hosts in a host equipment modification scheme and the feasibility is low are solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method, device and terminal equipment for implementing network conversion based on the transition from PNAT (PrefixNetworkAddressTranslation, prefix network address translation) to IPv6 (InternetProtocolVersion6, Internet Protocol Version 6). Background technique [0002] With the rapid development of Internet technology, the current IPv4 (Internet Protocol Version 4, Internet Protocol Version 4) address resources are increasingly exhausted. Under the current situation, it is inevitable to migrate from IPv4 to IPv6. However, due to the widespread application of IPv4 networks, it is impossible for IPv6 to completely replace IPv4 in the short term. Therefore, the two network technologies will coexist for a long time until IPv4 completely transitions to IPv6. [0003] Among them, how to realize the interconnection and smooth transition between IPv4 network and IPv6 network is an...
