Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. However, it should be noted that the following embodiments are only examples for helping to understand the technical solutions, and are not intended to limit the present invention.

[0025] The invention provides a method for acquiring IPv6 configuration information in an IPv6 transitional network, and the IPv6 transitional network includes an IPv4 network and an IPv6 network. The network may also include a user-side device connected to the IPv4 network, for example, the user-side device supports IPv6 rapid deployment (IPv6 rapid deployment, 6rd) technology or other IPv4-based IPv6 , such as 6to4 technology, Intra-Site Automatic Tunnel Addressing Protocol (Intra-Site Automatic Tunnel Addressing Protocol, ISATAP) technology, etc.

[0026] In the embodiment of the present invention, the user-side device sends an IPv6 configuration information ac...

Abstract

The present invention discloses a method for obtaining IPv6 configuration information in an IPv6 transition network. The network includes an IPv4 network and an IPv6 network. An apparatus for providing IPv6 configuration information in the IPv4 network receives an IPv6 configuration information obtaining request packet sent by a user side device, where the request packet is a DHCPv4 packet, and includes identification information, and the identification information is used to identify IPv6 configuration information that the request packet requests to obtain. The apparatus for providing IPv6 configuration information sends a response packet to the user side device, where the response packet is a DHCPv4 packet, and carries the IPv6 configuration information that the request packet requests to obtain. The advantages of the present invention lie in that automatic configuration for a user side device which needs to traverse the IPv4 network to access the IPv6 network is implemented, and efficiency is greatly improved compared with a manual configuration method in the prior art.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for acquiring IPv6 configuration information in an IPv6 transition network, a network system and an IPv6 configuration information providing device. Background technique [0002] At present, with the rapid popularization of network terminals, more and more network devices have entered the Internet, requiring Internet Protocol (IP) addresses for communication, leading to the gradual exhaustion of the currently used Internet Protocol version 4 (IPv4) IP addresses . The sixth version of the Internet Protocol (IPv6) has been considered as the core standard of the next generation Internet. [0003] In order to support the transition from IPv4 to IPv6, researchers have proposed a variety of interworking technologies. Dual-Stack technology is the most convenient, but the cost of upgrading all network infrastructure, services, applications and user terminals to dual-stack is extremel...
