Embodiment Construction

[0059] The invention solves the problem that the IPv4 application environment communicates through the IPv6 network address by adopting the functional entity (hereinafter referred to as the bridging entity) for bridging from the IPv4 application environment to the IPv6 network.

[0060] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0061] Such as figure 2 As shown, it is a functional structure diagram of a bridging entity realized by a software driver, and the bridging entity is located between the IPv4 application entity and the IPv6 network interface of the network node to realize the bridging between the two. An IPv4 application entity is usually an IPv4 application program.

[0062] Such as image 3 As shown, it is a functional structure diagram of the bridging entity implemented by a hardware entity. The IPv4 application entity accesses the IPv6 network through the IPv6 bridging hardwar...

Abstract

The invention discloses a method and device of network communication through IPv6 (internet protocol version 6) at an IPv4 (internet protocol version 4) application environment, and the method comprises: a bridging entity establishes a mapping relationship between an IPv4 application entity address of and an IPv6 address of the node; the bridging entity acquires the IPv6 address corresponding to an opposite terminal communication node, distributes a virtual IPv4 address for the opposite terminal communication node, and establishes a mapping relationship between the IPv6 address and virtue IPv4 address of the opposite terminal communication node; the bridging entity converts an IPv4 message sent by the IPv4 application entity through the mapping relationship of the IPv4 application entity address of the node and the IPv6 address of the node, and the mapping relationship of the IPv6 address and virtual IPv4 address of the opposite terminal communication node into an IPv6 massage and sends the IPv6 massage to an IPv6 network interface; and the IPv6 network interface forwards the IPv6 massage to the opposite terminal communication node.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and equipment for communicating through an IPv6 network in an IPv4 application environment. Background technique [0002] The Internet mainly uses 32-bit IPv4 addresses, but IPv4 addresses will be exhausted within a few years. [0003] The current solution is to use 128-bit IPv6 addresses, therefore, operators will assign IPv6 addresses to users in the near future. [0004] On the other hand, the application program of the IPv4 network user terminal adopts the environment of IPv4. For software manufacturers, migrating applications from IPv4 to IPv6 requires a large investment, but there is basically no return at present, so software manufacturers have little incentive to migrate and upgrade applications, which leads to a lack of IPv6 applications. [0005] In this way, the following problem needs to be solved: how to use the IPv4 application program under the condition that t...
