Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] Such as figure 1 As shown, the main application scenario of the present invention is: the connected equipment (such as set-top box, PC, intelligent terminal, etc.) The terminal gateway (CPE) forwards data from the LAN side to the WAN side, and the WAN interface side of the customer terminal gateway (CPE) is connected to the IPv6-only network.

[0038] Based on the CPE equipment above the Linux kernel 2.6.22, the present invention provides the following implementations: as figure 2 As shown, a Linux-based DS-Lite implementation method includes the following steps:

[0039] Step 100, utilize customer terminal gateway (CPE) to initiate call request to gateway control server (BNG), set up the connection with IPv6 network at WAN interface, obtain IPv6 link address by Neighbor Discovery Protocol, open DHCPv6 Client function and RADVD function (Linux Provided Rou...

Abstract

The invention discloses a Linux-based dual-stack lite (DS-lite) implementation method and customer premise equipment (CPE) access equipment thereof. A DS-Lite function is realized based on a Linux software mode by the Linux-based DS-lite implementation method, and an address family transition router (AFTR) server address is acquired by using a dynamic host configuration protocol version 6-Option64 (DHCPv6-Option64) in gateway equipment; a tunnel is established under an internet protocol version 6 wide area network (IPv6WAN) connection; the interconversion between an IPv4 domain name server (DNS) and an IPv6 DNS is performed by a DNS proxy; resolution is realized; and in such a way, an IPv4 data packet at the local area network (LAN) side of a gateway is transmitted in a network environment of IPv6-only after being processed by the gateway, and therefore, the requirement on hardware is lowered, and an access implementation way is simplified.

Description

technical field [0001] The invention relates to the technical field of DS-Lite, in particular to a Linux-based DS-Lite implementation method and a CPE access device thereof. Background technique [0002] DS-Lite (Dual-Stack Lite) lightweight dual-stack technology is an IPv4-in-IPv6 tunneling technology that enables dual-stack or IPv4-only hosts to access IPv4 network resources in an IPv6-only access network environment. Realize the coexistence of IPv4 and IPv6. [0003] At present, with the exhaustion of IPv4 allocatable address resources, the Internet adopts IPv6 network has become the development direction of the next generation Internet, and more and more operators have begun to deploy IPv6 networks in the access network and core network. However, due to the limitations of a large number of original application layer software and deployed terminal hardware, IPv4 and IPv6 services will need to coexist for a long time in the future. Then, in the environment of IPv6-only a...
