Problems solved by technology

Unable to achieve heterogeneous network redundancy, that is, the main line and the redundant line must use the physical telephone line of the same telecommunications company
The maximum redundant bandwidth of the client is 128k, which will cause a bottleneck for future use
Poor billing for redundant ISDN or dial-up

Abstract

Provided is a network redundancy system. When a rounter at a transmitting end detects a main circuit in disconnecting state, a name of a takeoff point of a user identification card is transmitted to 3G network. After the 3g network identifies the name of the takeoff point, turns on IP route at the transmitting end to a MPLS network, to build an IPsec channel, causing the router to guide network flow at the transmitting end to a secure channel. A first network device of the MPLS network inquires a routing list and IP routing information corresponding to the secure channel, marks a group at the routing end with VPN volume labels and MPLS volume labels, and transmitting the group to the MPLS network. A second network device of the MPLS network inquires the network which the group belongs to, removes the network volume labels of the group, and transmitting the group to an IP network at a receiving end.

Description

technical field [0001] The present invention relates to a network communication system, and in particular to a virtual private network (Virtual Private Network, VPN for short) network redundancy (redundancy) system and a processing method thereof. Background technique [0002] "Virtual Private Network (VPN)" is the most eye-catching operation mode in network applications in recent years, because it uses public networks instead of private lines to connect to enterprise LANs, which not only greatly reduces construction costs, but also improves Ease of future expansion. Generally, VPNs can be classified into Customer Premises Equipment (CPE for short)-based VPNs and Network-based VPNs. The former mainly uses technologies such as Layer Two Tunneling Protocol (Layer Two Tunneling Protocol, referred to as L2TP) or Internet Protocol Security (Internet Protocol Security, referred to as IPSec) by the enterprise client with its own equipment to communicate with the remote CPE. The -...
