Embodiment Construction

[0034] The method and device for communicating between an IPv6 host with an IPv4 application and an IPv4 communication peer provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0035] When an IPv6 host with an IPv4 application communicates with an IPv4 communication peer, it involves converting an IPv4 data packet into an IPv6 data packet and transmitting it through the IPv6 network. For this reason, the present invention provides a kind of method that IPv4 packet is converted into IPv6 packet, comprising:

[0036] The IPv6 host combines the IPv4 source address in the IPv4 data packet with the IPv6 prefix assigned to the IPv6 host to generate the IPv6 source address in the IPv6 packet header in the converted IPv6 data packet; and combines the IPv4 destination address in the IPv4 data packet with the set The well-known prefix (Well-known Prefix, WKP) combination, generates the IPv6 destination address in the IPv6 pac...

Abstract

The invention relates to the field of mobile communication, in particular to a method for an IPv6 host computer with IPv4 application to perform communication. The method comprises the following steps that: the IPv4 application generates a corresponding IPv4DNS request data packet according to an acquired IPv4 address and an acquired DNS address; the IPv6 host computer converts an IPv4 packet header into an IPv6 packet header and generates an IPv6DNS request data packet which is transmitted to a DNS server through an IPv6 network; the IPv4 application determines the IPv4 address of an IPv4 communication opposite end for performing communication according to a received DNS replay message data packet, and then generates an IPv4 application data packet transmitted to the IPv4 communication opposite end; after the packet header conversion performed by the IPv6 host computer, the IPv6 packet header is transmitted to an NAT device through the IPv6 network; and the NAT device converts the IPv6 packet header into the IPv4 packet header, and then the IPv4 packet header is transmitted to the IPv4 communication opposite end through an IPv4 network. The method realizes the communication between the IPv6 host computer with the IPv4 application and the IPv4 communication opposite end, and greatly reduces processing burden of a system, thereby lowering the probability of single-point failures and providing convenience for smooth migration and transition from the original IPv4 application to an IPv6 system.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to the technology for hosts with IPv4 applications to communicate through IPv6 networks. Background technique [0002] With the exhaustion of global IPv4 (Internet Protocol version 4, Internet Protocol version 4) addresses and the service's requirement for terminals to be "always online", the deployment of IPv6 (Internet Protocol version 6, Internet Protocol version 6) technology will become inevitable . In order to gradually introduce the concept of IPv6 network, the construction of IPv6 network and IPv4 / IPv6 dual-stack network will be the first step in the deployment of IPv6 technology. However, the current hosts have a large number of IPv4 applications, and the number of IPv6 applications is negligible compared with them. Therefore, how to solve the access and intercommunication of IPv4 applications between hosts in the IPv6 network in the initial stage of the IPv6 tr...
