Abstract

The invention discloses a hot standby method and device for CGN (Carrier Grade Network) equipment. The method comprises the following steps of: building a detection link between main equipment and spare equipment; switching the main equipment into the main state; switching the spare equipment into the spare state; building a backup channel on a detection link; and backing up information to the spare equipment by the main equipment via the backup channel. According to the hot standby method and device, the problem in the relevant technology that the service data of the CGN equipment under the three-layer network environment can not be backed up can be solved, and the CGN equipment can be subjected to hot standby under the three-layer network environment so as to effectively improve the service operation stability of the CGN equipment to further improve system performance.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for dual-system hot backup of network address translation (Carrier Grade Network Address Translation, referred to as CGN) equipment. Background technique [0002] Carrier-grade CGN is a technology for converting address information in the carrier network. With the exhaustion of IPv4 address resources, operators urgently need to solve the problem of address resources. [0003] Dual-stack lite Carrier Grade Network Address Translation (DS-Lite CGN for short) is a network address translation technology under the transition from an IPv4 network to an IPv6 network. Such as figure 1 As shown, it is a DS-Lite CGN centralized deployment scenario. The access terminal sends an IPv4 message to the access gateway device, and the access gateway device encapsulates it into a 4in6 tunnel message and forwards it to the CGN device through the tunnel (soft wire). After the...
