Problems solved by technology

[0003] Although the above IPv6 address format is tightly coupled with the corresponding IPv4 address, it can meet most application scenarios, but in some application scenarios that have special requirements for publishing the IPv6 format, the algorithm cannot be well adapted
For example, some servers want to embed some service-related information bits in the virtual IPv6 address, or the local administrator cannot manage and control the generation process of its IPv6 address, or some operators cannot assign IPv6 prefixes to translation equipment, and can only provide translation services. The device is assigned one or more IPv6 addresses, which cannot meet the format requirements of RFC6052, etc.
In this case, a flexible mapping algorithm is needed, which can perform static stateless one-to-one mapping between the flexibly generated IPv6 address and the original IPv4 server address, but the current translation technology cannot meet the above requirements

Abstract

This application relates to a stateless flexible mapping algorithm for IPv6 / IPv4 access. By constructing an IPv6 / IPv4 stateless flexible mapping table on the translation gateway, several fixed mapping tables between specified IPv6 addresses and specified IPv4 addresses are added as needed Items, and merged with the IPv6 / IPv4 mapping algorithm table items stipulated in RFC6052 to realize a unified IPv6 / IPv4 flexible mapping table based on longest prefix matching, which can adapt to various application scenarios and user needs of IPv6 / IPv4 access. The present invention supports hiding the real IPv4 address of the server from IPv6 users, supports IPv4 servers to issue encrypted IPv6 addresses, and realizes security protection. No matter how the IPv4 address of the internal server changes, the externally issued IPv6 address always remains unchanged, maintaining user access to services stability.

Description

technical field [0001] The present disclosure relates to the technical field of communication, in particular to a stateless flexible mapping algorithm, device and control system for IPv6 / IPv4 access. Background technique [0002] IPv6 is the core network protocol of the next generation Internet. However, IPv4 and IPv6 are not compatible at the address and protocol levels. Therefore, in today's coexistence of IPv4 and IPv6 networks, a simple, feasible, and scalable IPv6 / IPv4 translation technology is needed to help IPv6 computers communicate with IPv4 computers. RFC6144 defines the scene and framework of IPv6 / IPv4 translation, and RFC6052 and RFC7915 respectively define and standardize the address mapping and protocol mapping of IPv6 / IPv4 translation. From this, two important translation technology categories are derived: stateful translation technology (RFC6146) and stateless translation technology (RFC6052 / RFC7915 / RFC6219). Among them, the stateful translation technology ...
