Embodiment Construction

[0021] The detailed technical content of the present invention will be specifically described below in conjunction with the embodiments.

[0022] In order to help better understand the present invention, the unit referred to in the present invention refers to a component of a system, for a device it can be an independent component, a single board, etc., for a large system, it It can also be a device. At present, the industry usually adopts N+1 backup method to back up important data in system units, but this backup can only be performed in units with the same function, and units with different functions in the system still need to be backed up independently.

[0023] On the other hand, in order to reduce production costs, equipment manufacturers adopt the same or compatible hardware design for many functional units in the equipment, and realize different business functions by running different functional software through programmable devices, which can make hardware developmen...

Abstract

The present invention discloses a many-to-one mixing backing up method to different functional unit. It contains 1, configuring standby unit and saving at least one unit functional software among required backing up functional unit, to make it normal running in standby state, other functional unit software temporary downloading according to requirement in main and standby unit reversion, 2, when one main unit gone wrong existing normal standby unit, system starting up main and standby reversion, 3, system notifying standby unit activating relevant functional software, changing it into new mainunit and having same function with original fault main unit, 4, system modifying relevant configuring to make originally traffic stream configuring to original fault main unit, whole converting to new main unit. Said invention makes backing up through one stand-by unit to functional unit with same hard ware but different software, which greatly reduces backing up unit number and satisfying systemreliable operation requirement.

Description

technical field [0001] The invention relates to a method for backing up data on different functional units in a communication system, in particular to a method for many-to-one mixing of data on units with the same or compatible hardware but different functions realized by software in a data communication system The method of backup. Background technique [0002] For fields with high reliability requirements, such as military, telecommunications, aerospace, industrial control, medical equipment and other fields, the reliability of products can be improved by continuously improving the development and production quality of each unit of the product. Although system reliability is helpful, it is not obvious. The best way to provide system reliability is to adopt a backup strategy for key resources (data) in the system. Therefore, in the case of high reliability requirements, the key resources (data) inside the equipment used are backed up, and the resources (data) between the k...
