These three sections are described in detail below, respectively.
(1) IPv6 user client
And the IPv6 user client supports the access to the application system through IPv 6. Fig. 5 is a block diagram of the structure of an IPv6 user client, and as shown in fig. 5, the IPv6 user client includes: the IPv6 address unit 11 and the IPv6 are connected with the management unit 12 and the HTTP message management unit 13, wherein:

The HTTP message management unit 13 stores HTTP message information, and transmits the message to the server via the IPv6 connection management unit.
(2) Soft load balancer
The soft load balancer supports the starting of two types of virtual addresses, namely IPv6 and IPv4, exposes the IPv6 virtual address to the IPv6 user client, establishes IPv6 connection with the client and receives an access request of the client. The IPv4 virtual address is exposed to the IPv4 external link web server, IPv4 connection is established with the web server, and the intercommunication between the IPv6 user client and the IPv4 external link web server is realized through IP address conversion.
Specifically, the soft load balancer establishes connection with an IPv6 user client and an IPv4 external link web server respectively, after receiving a client data message, address conversion is carried out, a source address in the data message is a client IPv6 address, a destination address is a virtual IPv6 address of the soft load balancer, the source address in the converted message is changed into a virtual IPv4 address of the soft load balancer, and the destination address is an IPv4 address of the web server. Meanwhile, the load balancer reads the real IPv6 address of the client, inserts the address into the X-Forwarded-For field in the HTTP header of the data message, and forwards the request to the web server after repackaging. The web server responds to the access request, returns the processing result to the soft load balancer, the soft load balancer receives the returned data packet, carries out address conversion again, the source address in the message before conversion is the IPv4 address of the web server, the destination address is the virtual IPv4 address of the soft load balancer, the source address in the converted message is changed into the virtual IPv6 address of the soft load balancer, the destination address is the IPv6 address of the client, and the data packet is forwarded to the client after conversion is completed.
For example, the client (IPv6 address: 1111:1111:1111:1111:: ABCD) initiates access to an IPv6 virtual address (2222:2222: 2222:: ABCD) of the soft load balancer, the source IP of the data message received by the soft load balancer is the IPv6 address of the client, the destination IP is the virtual IPv6 address of the soft load balancer, and the HTTP header X-Forward-For field of the data message is null. After receiving the data message, the soft load balancer converts the source address in the data message into a virtual IPv4 address (2.2.2.2) of the soft load balancer, converts the destination address into an IPv4 address (1.1.1.1) of the web server, simultaneously reads the real IP (1111:1111:1111:1111: ABCD) of the client, writes an X-Forwarded-For field in the HTTP header of the data message into the IPv6 address, and encapsulates the data message and forwards the data message to the web server. And returning after the web server processes the access request, wherein the source address in the message received by the soft load balancer is the IPv4 address (1.1.1.1) of the web server, and the destination address is the virtual IPv4 address (2.2.2.2) of the soft load balancer. The soft load balancer carries out address translation again, and the source address in the translated message becomes the virtual IPv6 address (2222:2222:2222:2222:: ABCD) of the soft load balancer, and the destination address is the IPv6 address (1111:1111:1111:1111:: ABCD) of the client.

And the IP address translation unit 24 is used for carrying out address translation on the IPv6 virtual address of the load balancer and the IPv4 real address of the external link web server, and the address is translated into bidirectional translation. The source address in the data message sent to the load balancer by the client is the IPv6 address of the client, the destination address is the virtual IPv6 address of the soft load balancer, the source address in the converted message is changed into the virtual IPv4 address of the soft load balancer, and the destination address is the IPv4 address of the web server. The source address in the data message sent by the web server to the load balancer is the IPv4 address of the web server, the destination address is the virtual IPv4 address of the soft load balancer, the source address in the converted message is changed into the virtual IPv6 address of the soft load balancer, and the destination address is the IPv6 address of the client. The contents of the address translation relationship table are shown in table 1 below:

s101: the IPv6 address unit sends the client HTTP request using the IPv6 address.
S102: the user request receiving unit receives the client request by using the IPv6 virtual address, and the two parties establish an IPv6 connection.
S103: the IP address translation unit translates the IPv6 address in the request into an IPv4 address and establishes a connection with an IPv4 out-link web server.

S108: the soft load balancer converts the IPv4 target address in the web server return message into an IPv6 address, and forwards the IPv6 address to the client.
S109: and the client receives the returned content of the soft load balancer and displays the webpage content in the out-link window.
In the embodiment of the invention, the IPv6 client initiates an access request to the IPv6 virtual address of the soft load balancer, and both sides establish TCP connection of IPv 6. After the connection is established, the soft load balancer searches for an IP of an external link web server hung under an IPv6 virtual address, then initiates an access request to an IPv4 address of the web server through an IPv4 virtual address through address translation, and the two parties establish TCP connection of IPv 4. At this time, the soft load balancer establishes connection with both sides of the client and the web server, and simultaneously stores the corresponding relation of the two different protocol connections.
After the connection of the two ends is established, the client sends an HTTP data message to an IPv6 virtual address of the soft load balancer through IPv6 connection, after the soft load balancer receives the data message, the source address and the destination address in the data message are converted according to the address conversion relation, the source address in the message before conversion is the IPv6 address of the client, the destination address is the virtual IPv6 address of the soft load balancer, the source address in the message after conversion is changed into the virtual IPv4 address of the soft load balancer, and the destination address is the IPv4 address of the web server. Meanwhile, the IPv6 address of the client is also inserted into the HTTP message header of the request, so that the real IP of the client can be acquired by the web server. After the IP address conversion is completed, the soft load balancer forwards the data message to the web server through the IPv4 connection, and the web server receives and processes the IPv4 request and returns the result to the IPv4 address of the soft load balancer.
After receiving the return message of the web server, the soft load balancer carries out IP address conversion again according to the address conversion relation, the source address in the message before conversion is the IPv4 address of the web server, the destination address is the virtual IPv4 address of the soft load balancer, the source address in the converted message is changed into the virtual IPv6 address of the soft load balancer, and the destination address is the IPv6 address of the client. After the IP address conversion is completed, the soft load balancer forwards the message to the IPv6 client, and the client receives the return message and completes the display of the out-link webpage content on the browser.
