Embodiment Construction

[0075] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention, and are not intended to limit the protection scope of the present invention.

[0076] The "cross-network" mentioned in the present invention refers to a client of an IPv4 network accessing a server of an IPv6 network, or a client of an IPv6 network accessing a server of an IPv4 network. The "first protocol" and the "second protocol" are respectively one of IPv4 and IPv6, and are different from each other. The "first protocol" is IPv4, and the "second protocol" is IPv6; or, the "first protocol" is IPv6, and the "second protocol" is IPv4. The network where the client is located uses the first protocol, and the network where the server is located uses the second protocol.

Abstract

The invention relates to the technical field of IPv4 / IPv6 (Internet Protocol Version 4 / Internet Protocol Version 6) communication, in particular to a method, a system and related device for transmitting a client source address across networks, and aims to solve the problem that the client source address is inconvenient to write into an XFF (Extensible Forwarding Function) field for transmission after an application layer of a data packet is encrypted. The method for transmitting the source address of the client across the network comprises the following steps that: an address injection devicereceives a first protocol data packet of the client, adds the source address of the client into an option field of a TCP (Transmission Control Protocol) or IP (Internet Protocol) packet header or an extended packet header of the IP packet, and transmits the source address of the client to protocol conversion device; a protocol conversion device performs protocol conversion and application layer decryption to obtain a second protocol data packet and sends the second protocol data packet to the source address information conversion device; and the source address information conversion device reads the source address of the client, adds the source address to the XFF field, and sends the second protocol data packet to the server. According to the invention, the problem that the encrypted datapacket is inconvenient to add the client source address to the XFF for transmission is solved.

Description

technical field [0001] The present invention relates to the technical field of IPv4 / IPv6 communication, in particular to a method, system and related equipment for transferring client source addresses across networks. Background technique [0002] With the depletion of IPv4 addresses, people began to use IPv6 networks to replace IPv4 networks. In the transitional stage of replacement, IPv4 and IPv6 networks often coexist. When users use IPv4 or IPv6 networks, there is also a gap between IPv4 and IPv6 networks. incompatibility issues. Because there is a problem of incompatibility between the two networks, the client's access request to the website cannot simply go directly from the client's browser to the website's server, and may pass through equipment such as a protocol conversion system or proxy server, so the server receives the client's When accessing the request, the source IP address in the data packet is no longer the source address of the client. [0003] In the pr...
