Embodiment 1

[0022] In this embodiment, the content intercommunication between IPv4 and IPv6 websites is quickly realized without upgrading and modifying the existing code of the website system. The specific implementation cases are as follows:

[0023] 1. The service provider applies for a domain name for the IPv6 application gateway, such as www.reyzar.com, and sets up an authorized DNS server for the domain name.

[0024] 2. The service provider deploys an IPv4 / IPv6 website content interworking system in the dual-stack data center. The system is built on a cloud computing distributed cluster and consists of IPv6 application gateway and cache system components. The application gateway is composed of a user request receiving module, a request parsing module, a content acquiring module, a protocol conversion module, and a content forwarding module, wherein the user request receiving module is used to receive HTTP access requests sent by IPv6 users; HTTP request, obtains the target server a...

Embodiment 2

[0026] This embodiment takes the IPv4 site of visiting Sina as an example, assuming that Sina.com has added the AAAA DNS resolution record to the IPv6 application gateway at the authorized DNS server, and the specific implementation cases are as follows:

[0027] 1. IPv6 users first send www.sina.com.cn AAAA DNS query request;

[0028] 2. Sina authorizes the DNS to return the AAAA DNS response pointing to the IPv6 application gateway;

[0029] 3. The user sends an HTTP request to www.sina.com.cn to the IPv6 application gateway, and the HTTP request is captured by the load balancing server;

[0030] 4. The load balancing server forwards the request to the IPv6 application gateway with the lightest load;

[0031] 5. The application gateway queries whether the cache is hit;

[0032] 6. In the case of a cache miss, the IPv6 application gateway suspends the user's HTTP request and initiates an HTTP request to the IPv4 website on behalf of the IPv6 user;

[0033] 7. The IPv4 webs...

Abstract

The invention discloses an application gateway technology and an application gateway system for realizing content interchange of Internet protocol version 4 / Internet protocol version 6 (IPv4 / IPv6) websites, and relates to the field of data communication. A method for realizing the content interchange of the IPv4 / IPv6 websites comprises the following steps that: an application gateway is arranged between a cross-network user and a website, the user can perform cross-network hypertext transfer protocol (HTTP) access by the proxy of the gateway, and the gateway can access a data packet Payload to perform IPv4 / IPv6 conversion so as to help an IPv4 website rapidly to move to an IPv6 network; and an HTTP access request of the user is guided to a specified platform by modifying an IP address and a domain name to the form of using the domain name of an IPv6 application gateway as a father domain name, and an IPv4 user can initiate HTTP access to an IPv6 website. According to the technology and the method, an Internet content provider (ICP) can be assisted in moving the IPv4 website to the IPv6 network under the condition that an application provider does not update and modify the conventional system; and meanwhile, the IPv6 network is provided for the IPv4 user to access, and the problem of blank access due to network outlinks is solved.

Description

Technical field: [0001] The invention relates to the field of data communication, in particular to an application gateway technology and system for realizing intercommunication of IPv4 / IPv6 website content. Background technique: [0002] As an important carrier for realizing informatization, broadband network is the key infrastructure for economic and social development. The current basic protocol of the Internet is IPv4 (Internet protocol version 4, Internet protocol version 4) using 32-bit addresses. After years of development, IPv4 has achieved great success. With the continuous growth of network scale and new applications, insufficient IP address space restricts the development of the Internet. As of February 3, 2011, the allocation of global IPv4 addresses has been completed, and on April 19, 2011, the distribution of Asia-Pacific IPv4 addresses has also been completed. China's Internet development will soon face the dilemma of no IPv4 addresses available. After year...
