Embodiment 1

[0073] A method for PPTP traversal in an IPv4-IPv6 interworking scenario, applied to a NAT64 server, refer to figure 1 , the method includes:

[0074] S102. Establish a session mapping relationship between the IPv6 client and the IPv4 server based on the NAT64 technology, wherein the session mapping relationship is a mapping relationship between the IPv6 address and the IPv4 address of the IPv4 server;

[0075] In the embodiment of the present invention, the NAT technology is used to establish the session mapping relationship between the IPv6 client and the IPv4 server. The NAT64 server is equivalent to a translation node. The session relationship of the IPv4 server realizes the session mapping relationship between the IPv6 client and the IPv4 server. The session mapping relationship is a mapping relationship between the IPv6 address and the IPv4 address of the IPv4 server. The establishment process will be described in detail below.

[0076] S104. Convert the IPv6 request ...

Embodiment 2

[0146] A device for PPTP traversal in an IPv4-IPv6 interworking scenario, applied to a NAT64 server, refer to Figure 5 , the device consists of:

[0147] The establishment module 20 is used to establish the session mapping relationship between the IPv6 client and the IPv4 server based on NAT64 technology, wherein the session mapping relationship is the mapping relationship between the IPv6 address and the IPv4 address of the IPv4 server;

[0148] The first conversion module 21 is used to convert the IPv6 request message sent by the IPv6 client into an IPv4 request message according to the session mapping relationship;

[0149] The first modification module 22 is used to modify the client Call ID and Peer's Call ID of the PPTP message in the IPv4 request message to obtain the modified IPv4 request message;

[0150] The first sending module 23 is configured to send the modified IPv4 request message to the IPv4 server;

[0151] The first receiving module 24 is used to receive ...

Embodiment 3

[0190] An embodiment of the present invention provides an electronic device, referring to Image 6 , the electronic device includes: a processor 30, a memory 31, a bus 32 and a communication interface 33, the processor 30, the communication interface 33 and the memory 31 are connected through the bus 32; the processor 30 is used to execute the executable module stored in the memory 31, For example a computer program. The processor implements the steps of the methods described in the method embodiments when the processor executes the program.

[0191] Wherein, the memory 31 may include a high-speed random access memory (RAM, RandomAccessMemory), and may also include a non-volatile memory (non-volatile memory), such as at least one disk memory. The communication connection between the system network element and at least one other network element is realized through at least one communication interface 33 (which may be wired or wireless), and the Internet, wide area network, loc...

Abstract

The invention provides a method, device and electronic instrument for PPTP cross in an IPv4-IPv6 intercommunication scene. The method comprises the following steps: based on a NAT64 technology, building a session mapping relation of an IPv6 client and an IPv4 server; according to the session mapping relation, converting an IPv6 request message to an IPv4 request message; modifying client Call ID and Peer's Call ID of a PPTP message in the IPv4 request message; sending the modified IPv4 request message to the IPv4 server; receiving an IPv4 response message returned by the IPv4 server, converting the IPv4 response message to an IPv6 response message, and modifying server Call ID and Peer's Call ID of the PPTP message in the IPv6 response message; sending the modified IPv6 response message tothe IPv6 client. The method is capable of, through managing the Call ID and Peer's Call ID in the request message and the response message, realizing the intercommunication of PPTP protocol data in the IPv4 and IPv6 networks, and relieving the technical problem in the prior art that the PPTP protocol message cross cannot be realized in the IPv4-IPv6 intercommunication scene.

Description

technical field [0001] The present invention relates to the technical field of Internet communication, in particular to a method, device and electronic equipment for performing PPTP traversal in an IPv4-IPv6 intercommunication scene. Background technique [0002] As an important carrier for realizing informatization, broadband network is the key infrastructure for economic and social development. With the increasing development of the Internet, the existing IPv4 (Internet Protocol version 4, Internet Protocol version 4) addresses are already in short supply, and it is impossible to avoid the problem that the IPv4 addresses are exhausted. IPv6 (Internet Protocol version 6, Internet Protocol version 6) with 128-bit IP addresses has completely solved the problem of insufficient IPv4 addresses, and has obvious improvements in address capacity, security, network management, mobility, and quality of service. It is the next generation A core standard adopted by internetwork protoc...
