Abstract

An embodiment of the invention provides an address distributing method, an address distributing equipment and an address distributing system. The address distributing method is applicable to the network with a BRAS (broadband remote access server) which is provided with a carrier grade network address translation and includes that the BRAS detects CGN faults locally set, receives access request transmitted by terminals and distributes IP (internet protocol) addresses of the public network to the terminals. When in CGN faults, terminal flow transfer is omitted, service restore time of the terminals of the BRAS is shortened and cost is reduced.

Description

technical field [0001] The present invention relates to information technology, in particular to an address allocation method, device and system. Background technique [0002] Carrier Grade Net Address Translation (CGN) refers to the large-scale deployment of IPv4 private addresses of Internet Protocol (Internet Protocol, IP) version 4 to achieve statistical multiplexing of current public network IPv4 addresses. technology. CGN is essentially a NAT technology, which is the process of converting the IP address in the IP datagram header to another IP address, so that multiple private network IP addresses can share a public network IP address. [0003] In the prior art, a backup BRAS needs to be set for a broadband remote access server (Broadband Remote Access Service, BRAS) in the network. The BRAS and the backup BRAS are respectively plugged with the same number of CGN single boards. If the CGN single board on the BRAS fails, Then the traffic on the BRAS can be switched to ...
