Embodiment Construction

[0048] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principles of the present invention.

[0049] first combined with figure 1 to attach Figure 4 The method described in the embodiment of the present invention is described in detail.

[0050] The method of the present invention needs to store the common data of the main machine and the standby machine in the database of the database server in advance, and read them when the main machine and the standby machine are initialized. At the same time, a database table TBSERVER needs to be set in the database, and two records are stored in the database table, which are respectively used to record the respective operating states of the main machine and the standby machine.

[0051]The two-machine ...

Abstract

The invention discloses a dual-computer switching method and a system thereof, wherein, the method comprises the following steps: public data of a main computer and a standby computer is put in a share database; a database table is preset in the database; the database table has two records which represent running state of the main computer and the standby computer respectively; the records in thedatabase table are checked according to a preset cycle to confirm the running state of the two computers, and the two computers are automatically switched according to the running state recorded in the database table. The method and the system overcome the problem that the data is synchronous and inconsistency in traditional dual-computer design technology; and a hardware DOG card is not needed any more, thus saving investment.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a dual-device switching method and system. Background technique [0002] With the rapid development of communication technology and computer technology, people have higher and higher requirements for computer communication network equipment, not only the content of network services, but also the quality of network services. One measure to improve network service quality is to improve the reliability of communication equipment. In order to improve the reliability of the equipment, the most commonly used method is to use the main and standby dual-machine mode for key network equipment. When the main machine fails, the standby machine takes over from the main machine to continue processing business through dual-machine switching. [0003] Dual-device switching is mainly applied to the core nodes of network-side devices, such as fixed network switches. In the existi...
