Embodiment Construction

[0034] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] The embodiment of the present invention provides a kind of IPv4 / IPv6 stateless translation algorithm, and the step flow is as follows figure 1 As shown, it specifically includes the following steps:

[0036] Step S1, setting up a translation gateway between the IPv4 Internet and the IPv6 server, configuring a set of IPv4 translatable address parameters, and configuring application layer protocol parameters to be processed.

[0037] Step S2, the IPv4 client sends the first type of IPv4 packet to the translation gateway.

[0038] Step S3, based on the information contained in the network layer protocol header, the transport layer protocol header and the application ...

Abstract

The invention discloses an IPv4/IPv6 stateless translation algorithm. By using information included in the head of an application layer protocol, packets with the same IPv4 address and the same port are mapped to different IPv6 addresses through an application layer, and IPv4/IPv6 translation from the same IPv4 address and the same service port to different IPv6 addresses and the same service port is achieved. According to the IPv4/IPv6 stateless translation algorithm, different pure IPv6 servers can be accessed by any IPv4 address in the IPv4 Internet, the pure IPv6 servers can provide services for IPv6 clients, and can also provide services for IPv4 clients by using the same port, the problem of the shortage of a public IPv4 address in a data center is solved effectively, and transition of Internet information resources from IPv4 to IPv6 is promoted.

Description

technical field [0001] The invention relates to the technical field of computer network communication, in particular to an IPv4 / IPv6 stateless translation algorithm. Background technique [0002] At present, in order to solve the problem of insufficient IPv4 addresses, the Internet Engineering Task Force (IETF) has designed the sixth version of the network protocol IPv6. Its address range is 2128, which can completely solve the problem of insufficient IPv4 addresses. However, due to various reasons, the IPv6 protocol is incompatible with the IPv4 protocol, and the interconnection and intercommunication between the two cannot be realized. Therefore, a method or technology is needed to realize the transition from IPv4 to IPv6. The industry has tried to use the "dual protocol stack" method to solve the problem of interconnection and interoperability, but the experience and lessons of IPv6 promotion in the past ten years have proved that it cannot access many IPv4 network inform...
