Problems solved by technology

However, this method needs to record the ports of all flows from the beginning. If the business volume is large or a DDoS attack occurs, the efficiency of mapping query will be greatly reduced, and the performance overhead will be greatly increased, which may cause the device to be unavailable.

[0061] S1. Configure the translation gateway on the IPv4 service side, and construct an IPv4 / IPv6 quasi-stateless address translation mapping table in the translation gateway;

[0062] Specifically, set up a translation gateway between the IPv4 server and the IPv6 Internet, and perform the following configurations:

[0063] Configure IPv4 routing to the translation gateway, that is, configure IPv4 L1 routing and L2 routing to the transla...

Embodiment 2

[0085] On the basis of the implementation technology in embodiment 1, in this embodiment, in order to reduce the mapping conflict effect, the size and algorithm of the L1 and L2 address pools are dynamically adjusted by the translation gateway based on the size and characteristic negative feedback information of the number of online IPv6 users measured, In order to reduce the effect of mapping conflicts.

[0086] In a possible implementation, optionally, further include:

[0087] Obtain the size and characteristic negative feedback information of the number of online IPv6 users;

[0088] receiving the size and characteristic negative feedback information of the number of online IPv6 users, and dynamically adjusting the first segment of the IPv4 private address pool L1 and the The size and algorithm of the second IPv4 private address pool L2.

[0089] Specifically, the address pool occupancy threshold is set to R, usually R=50%, and the first segment of IPv4 private address p...

Embodiment 3

[0095] Furthermore, according to another aspect of the present disclosure, a control system is also provided.

[0096] The control system of the embodiment of the present disclosure includes a processor and a memory for storing instructions executable by the processor. Wherein, the processor is configured to implement any one of the aforementioned quasi-stateless adaptive mapping methods for IPv4 / IPv6 access when executing the executable instructions.

[0097] Here, it should be noted that the number of processors may be one or more. Meanwhile, in the control system of the embodiment of the present disclosure, an input device and an output device may also be included. Wherein, the processor, the memory, the input device and the output device may be connected through a bus or in other ways, which are not specifically limited here.

[0098] As a computer-readable storage medium for a quasi-stateless adaptive mapping method for IPv4 / IPv6 access, the memory can be used to store ...

Abstract

This application relates to a quasi-stateless adaptive mapping method for IPv4 / IPv6 access. The method deploys a translation gateway on the IPv4 service side, and builds a first type of IPv4 / IPv6 static mapping table and a second type of static mapping table in the translation gateway. An IPv4 / IPv6-like dynamic mapping table, which flexibly combines stateless static mapping and dynamic mapping on demand, and flexibly adjusts the parameters of the IPv4 / IPv6 mapping algorithm based on measurement negative feedback, thereby maintaining the high performance and security of the existing stateless translation algorithm On the basis of good, good traceability characteristics and other advantages, it can adapt to elastic burst IPv6 load, and at the same time, when dealing with large-scale IPv6 online user access, it greatly reduces system overhead compared with existing technologies.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular to a quasi-stateless adaptive mapping method and control system for IPv4 / IPv6 access. Background technique [0002] The address range of IPv4, the fourth version of the network protocol widely used on the Internet at present, is 2 32 , whose address space has been allocated in 2011. As an alternative to IPv4, the next-generation Internet protocol IPv6 was announced by the Internet Engineering Task Force (IETF) in December 1998 and has been deployed on a large scale around the world. [0003] According to Cisco data, by August 2021, among the global end users, the proportion of users supporting IPv6 has reached more than 35%. Therefore, more and more existing IPv4 servers need to support IPv6 user access. However, since the IPv4 protocol and the IPv6 protocol are not compatible, how to solve the problem of IPv6 users accessing the IPv4 server needs to be solved...
