End-to-end multi-link multi-node full-automatic redundant backup routing system

Abstract

The invention relates to an end-to-end multi-link multi-node full-automatic redundant backup routing system which comprises a user side, a main link node machine, a backup link node machine, a core IPnetwork platform and an upstream operator network platform. The user side is connected with the main link node machine and the backup link node machine. The core IP network platform is connected withthe main link node machine, the backup link node machine and the upstream operator network platform. The backup link node machine can realize full automatic redundancy and backup for the informationof the main link node machine. When the main link node machine fails, the backup link node machine automatically replaces the main link node machine. The user side comprises two user firewalls which are corresponding to the main link node machine and the backup link node machine respectively. Compared with the prior art, the end-to-end multi-link multi-node full-automatic redundant backup routingsystem provided by the invention has the advantages of low cost, simple implementation, load balancing device input saving and the like.

Description

technical field [0001] The invention relates to a routing control system, in particular to an end-to-end multi-link multi-node fully automatic redundant backup routing system. Background technique [0002] At present, enterprise customers rent multiple links to access the Internet service provider. Since it is a static routing method, in order to achieve automatic redundancy and backup functions between the two links, it is necessary to invest in expensive load balancing equipment such as F5. The smart DNS domain name resolution system, for the VPN system, is implemented by 2 ips, which will bring a huge workload of client debugging, and the general enterprise cannot afford its price and the complex smart DNS domain name resolution system.

Problems solved by technology

[0002] At present, enterprise customers rent multiple links to access the Internet service provider. Since it is a static routing method, in order to achieve automatic redundancy and backup functions between the two links, it is necessary to invest in expensive load balancing equipment such as F5. The smart DNS domain name resolution system, for the VPN system, is implemented by 2 ips, which will bring a huge workload of client debugging, and the general enterprise cannot afford its price and the complex smart DNS domain name resolution system. To sum up, the traditional link Redundancy and backup methods have the following disadvantages:

[0003] 1) If the customer accesses the operator through dynamic routing (such as BGP dynamic routing protocol), the access fee is expensive, and the enterprise needs to apply for an ASN (Autonomous Domain System Number) and a portable IP address from the world's four major IP address allocation committees (that is, not forced to change with the change of upstream operators), and enterprises need to configure senior network experts who are proficient in routing and switching technologies. At present, in China, only ISP operators and very large enterprises have the ability to adopt such solutions. General corporate customers do not apply

[0004] 2) More than 99% of enterprises can only use static routing to access the same operator or multiple different operators, but since the IP addresses allocated by multiple operators must be different, and they cannot be mixed and penetrated, When one of the links is interrupted, there is no guarantee that the IP information of this link can continue to be used. Only expensive link load balancing equipment such as F5 can be used to convert the internal IP information of the enterprise to the IP corresponding to another link through NAT. Address information, and at the same time through the intelligent DNS domain name resolution system, to notify external access users, redirect their access information to the IP information of the available link, the technical system is very complicated, the cost is very high, and the operation and maintenance cost of the system is very high. high

Moreover, the intelligent DNS system cannot achieve 100% accurate positioning.

[0005] 3) Generally, enterprises apply for two leased line links to the operator at the same time, and the cost is undoubtedly doubled. According to the traditional method, ISDN is used as a backup. Due to the ISDN dial-up method, the bandwidth is too low to meet the broadband requirements of today's enterprises. customized access requirements

[0006] 4) The backup considered by the prior art is not comprehensive enough
