Abstract

The present invention provides a network address conversion method comprising: obtaining an IP data message, extracting an IPV4 network address to be converted from the message, converting the IPV4 network address into an IPV6 network address according to predetermined rules, and the IPV6 network address Contains physical address information, replaces the IPV4 network address in the message with the IPV6 network address and forwards it, so that at least in the prior art, the message needs to be decapsulated to the IP layer, resulting in low forwarding efficiency, and the number of supported IPv4 addresses for each Limited, leading to the problem of increasing the cost of network deployment.

Description

technical field [0001] The invention relates to the fields of communication and computer, in particular to a network address conversion method and device. Background technique [0002] Internet Protocol Version 4 (hereinafter referred to as IPv4) is rich in services. Although some of them are transitioning to Internet Protocol Version 6 (hereinafter referred to as IPv6), IPv4 users are still relatively large. To solve the IPv4overIPv6 scenario, a number of transition technologies for the IPv4overIPv6 scenario have been formed, and Light weight 4over6 and DSLite are two of them. Lightweight 4over6 is an improved version of DS-Lite technology. The biggest improvement is to transfer the NAT44 (Network Address Transfer 44) conversion to the customer terminal equipment (Customer Premise Equipment, hereinafter referred to as CPE), and the IPv4 address allocated by the tunnel is shared. The principle is The CPE completes the NAT44 conversion first, and then encapsulates the IPv6 p...
