Abstract

The invention discloses a method and system for achieving real-time synchronization of user data. The method comprises the steps that an AAA server receives authentication information of a user; after authentication succeeds, the AAA server sends a private IPv4 address of the user or a public IPv6 address and a source TCP/UDP port to a CGN device through a signaling interface; the CGN device forms a mapping table and feeds the mapping table back to the AAA server, wherein the mapping table comprises a private IPv4 address of the user or the public IPv6 address, the source TCP/UDP port, the public IPv4 address which is mapped through the CGN device and the source TCP/UDP port which is mapped through the CGN device; the AAA server sends the corresponding relation between a user account and a public IPv4 address to a DPI device. By the adoption of the method and system, real-time synchronization of user data is achieved.

Description

technical field [0001] The invention belongs to the field of IP (Internet Protocol), and in particular relates to a method and a system for realizing real-time synchronization of user data. Background technique [0002] When public IPv4 (Internet Protocol version 4) addresses are gradually exhausted, operators can only assign private IPv4 addresses or IPv6 (Internet Protocol version 6) addresses to users to complete user network access. [0003] Considering that most of the current Internet content is still based on IPv4, after assigning such addresses to users, operators also need to consider how to implement private IPv4 addresses or IPv6 addresses by deploying NAT (Network Address Translation) devices. Translation of addresses to public IPv4 addresses. [0004] Generally, operators will centrally deploy CGN (Carrier Grade NAT, carrier-grade network address translation) equipment at the egress of the MAN. In order to conduct in-depth analysis and control of network traff...
