Problems solved by technology

However, in scenarios such as load balancing, when performing NAT64, the IP addresses of both parties in communication will also be lost, resulting in the inability of both parties to know the IP address of the other party, which brings inconvenience to many applications.

Embodiment Construction

[0041] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0042] At present, when the communication protocol versions of the communication parties are different, it is impossible to obtain the source address of the opposite end, which brings a lot of inconvenience. In order to improve these technical problems, in some embodiments of the present application: during the communication protocol negotiation proce...

Abstract

The embodiment of the invention provides an address acquisition method, equipment, an address acquisition system and a storage medium. The address acquisition system comprises a first communication end, gateway equipment and a second communication end, wherein the first communication end is used for sending a first acknowledgement packet used for acknowledging communication connection to the gateway equipment in the process of communication protocol negotiation with the second communication end, wherein the first acknowledgement packet comprises a source address of the first communication end; the gateway equipment is used for converting the first acknowledgement packet into a second acknowledgement packet adaptive to the communication protocol version of the second communication end, configuring the source address of the first communication end into the second acknowledgement packet, providing the second acknowledgement packet for the second communication end so as to establish communication connection between the first communication end and the second communication end; and the second communication end is used for acquiring the source address of the first communication end from the second acknowledgement packet. Therefore, in the embodiment, under the condition that the communication protocol versions of the first communication end and the second communication end are different, the second communication end can also obtain the source address of the first communication end.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an address acquisition method, device, system and storage medium. Background technique [0002] With the development of communication technology, IPv4 address resources become less and less, and IPv6 emerges as the times require, which makes two versions of IP addresses exist in the network environment, namely IPv4 and IPv6. [0003] At present, technologies such as NAT64 (Network Address and Protocol Translation) can be used to realize mutual access between IPv4 and IPv6. However, in scenarios such as load balancing, when NAT64 is performed, the IP addresses of the two communicating parties are also lost, resulting in the inability of both parties to know the other party's IP address, which brings inconvenience to many applications. Contents of the invention [0004] Multiple aspects of the present application provide an address acquisition method, device...
