Problems solved by technology

In this way, when a failure occurs, the faulty device needs to be shut down, and then manually connected to the backup device, and sometimes even related configurations need to be reconfigured. It can be seen that this method not only responds slowly, but also causes business interruption.

Embodiment 1

[0050] Embodiment 1: This embodiment is the case of using multiple backup ports.

[0051] figure 2 It is a schematic diagram of the data flow direction in which the port backup is used to realize the 1+1 backup of data services in the present invention. figure 2 In the same data communication switch 20, there is one main port A21, two standby ports: standby port B22 and standby port C23, and port D24 is the corresponding output port of the main and standby port. Assuming that there is a server 26 connected to the main and standby ports, the input data of the main and standby ports comes from the same database in the server 26, and the data reaches the server 27 through the data communication switch 20. In this embodiment, it is assumed that the server 26 itself supports port backup, that is, when a port failure occurs on the data communication switch 20, the server 26 can complete corresponding port switching according to the detection of link connectivity. For example: wh...

Embodiment 2

[0072] Embodiment 2: This embodiment is the case of using a single backup port.

[0073] image 3 It is a schematic diagram of the data flow direction in which the port backup is used to realize the redundant backup of data services in the present invention. image 3 On the same data communication switch 30, there is a main port A31, a backup port B22, and port 24 is the corresponding output port of the main and backup port. Assuming that a server is respectively connected to the main and standby port sides, the input data of the main port comes from a database in the server 35, and the data arrives at the server 37 through the data communication switch 30; the input data of the standby port comes from another database in the server 36, and the data It reaches the server 37 through the data communication switch 30. Here server 36 is a local backup server of server 35 .

[0074] refer to Figure 4 The flow chart of the port backup of the present invention, the redundant bac...

Abstract

The invention discloses a method for achieving data business duplicate. The method comprises: user designs the port number of the main port, the spare port and the relation between the main port and the spare port: 1+1 duplicate or redundancy duplicate as port duplicate to set the parameter of the order, wherein the ports has the same brand wide and are in one data communicating machine. When the main port faults, it uses the fault alarm automatic trigger to allow the automatic switch of the main port and the spare port.

Description

technical field [0001] The invention relates to data service backup technology, in particular to a method for realizing data service backup on the same data communication exchange. Background technique [0002] In order to improve the reliability of communication equipment, data services need to be backed up. [0003] Currently, the most common method for backing up data services is load sharing. The implementation of this method is: on the same data communication switch, multiple ports are used to share the data services. When one of the ports or links fails, the data services on it are switched to another port, so as to achieve Backup of data services. [0004] The port management module is a software module that manages ports and their links in the data communication switch; automatic triggering of fault alarms is a software module that monitors port and link failures on the data communication switch. The channel communication transmits some relevant information to ver...
