Abstract

The invention discloses tunnel certification method and device, relates to the technical field of data communication, and aims at solving the problem of the prior art that the tunnel certification efficiency is low during performing tunnel certification from IPv4 to IPv6. The method specifically comprises the following steps: acquiring a certification message from a CPE (Central Processing Element) through an IPv4 over IPv6 tunnel forwarding module; de-encapsulating a check code carried by the passage from the certification message; checking whether the check code appears at the site through a check code module; sending a tunnel building instruction to a CGN tunnel managing module while finding out the check code; building an IPv4 over IPv6 tunnel for the certification message through the CGN tunnel managing module. According to the technical scheme provided by the embodiment, the method and device are mainly applied to the building process of the IPv5 over IPv6 tunnel.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a tunnel authentication method and device. Background technique [0002] The existing DS-Lite (full name in Chinese: Lightweight Dual Stack, full name in English: Dual-Stack lite) technology uses IPv4over IPv6 (full name in English: Internet Protocol Version 4 over Internet Protocol Version 6, full name in Chinese: Internet Protocol Version 4 to Network protocol version 6) tunnel and NAT (full name in Chinese: Network Address Translation, full name in English: Network Address Translation) technology combination, allowing CPE (full name in English: Customer Premise Equipment, full name in Chinese: user end equipment) Allocate IPv4 addresses so that multiple IPv4 CPE private networks can share IPv4 addresses, thereby alleviating the current problem of IPv4 address exhaustion. The implementation of DS-Lite technology is: use IPv4 over IPv6 tunnel as the traffic path betw...
