Embodiment Construction

[0035] The main idea of ​​the present invention is: in the system, the unit state is divided into active state and standby state, the unit in the active state executes the business function of the system, and the unit in the standby state does not execute the business function of the system, and certain conditions are set. When the above conditions are met, the state switching of the active and standby units occurs.

[0036] In the method of the present invention, the backup unit does not perform the service function of the system, and the unit is damaged or isolated. If the unit is removed from the system, it will not affect the service function being executed by the system.

[0037] In the method of the present invention, when the master unit fails, such as a certain subsystem in the master unit is abnormal, whether the switch of the master and backup units occurs is determined according to conditions. When the conditions are met, active-standby switchover occurs; when the c...

Abstract

The invention provides a condition-based main / standby switching method and a condition-based main / standby switching device in a redundancy backup system. The method comprises the following steps of: presetting a unit state in the system, wherein the unit state is divided into a main state and a standby state, and a unit in the main state executes the service function of the system; presetting a condition for switching the main state and the standby state between units, wherein the condition comprises either switching according to the set time or unallowed switching; and monitoring the system state, and when the condition is met, switching the main state and the standby state between units according to the condition. By setting the main / standby switching condition, a condition mechanism is arranged in a general main / standby redundancy mode, and the condition can be set according to the user need; therefore, various use requirements of a user are better met.

Description

technical field [0001] The invention relates to telecommunication equipment in the field of communication, especially next-generation network equipment with large capacity and high density. Background technique [0002] The communication network has high requirements on reliability, especially the high-level telecommunications equipment at the site, which requires redundant design and backup strategy. The general redundancy design has 1+1 or N+1 redundancy, and the backup strategy is divided into load sharing mode or master-backup mode. For mutual active and standby units, the usual switchover strategy is that the unit regularly detects the state of itself and the backup unit and compares them. perform business in the system. This switching strategy is generally completed automatically by the system. Once the active single board in the backup fails and goes out of service, the system automatically switches the standby single board to the active one without manual intervent...
