Problems solved by technology

In the existing backup technology, it is generally cold backup. The disadvantage of cold backup is that when the standby board takes over the work of the main board, the service board needs to be restarted, which will cause the interruption of the work of the A short-term single point of failure in the network affects normal business

Embodiment Construction

[0034] The invention is applied to distributed equipment, which is generally divided into a main control board and a service board. The main control board is used to control and manage the entire device, while the service board is responsible for forwarding data and so on. The invention designs a hot backup module to complete the backup work in a unified manner. The data module does not need to consider the backup work. It only needs to register the hot backup interface to receive the message sent by the hot backup module, pack the data, and send the data through the unified interface of the hot backup Just give the hot backup module, and the backup process is managed by the hot backup, which simplifies the design of the hot backup work of the data module.

[0035] In the method of the present invention, at first the inter-board communication modules are respectively arranged on the main control board and the service board, and the inter-board communication interface addresses...

Abstract

The method sets up communication module between boards, registers communication interface address between boards on main board and service boards. Also the method sets up warm back-up module, registration table, and interface address of warm back-up and data backup interface on main board and standby board, which are utilized as main control board. When data backup starts, both of main board and standby board is in warm back-up state. Then, mass data backup between main board and standby board is completed in real time or in preset time. If original main board is in trouble, the standby board becomes as new main board. Data exchange is carried out between new main board and service boards. Thus, when in normal operation, data on main board are backed up to standby board. If main board is in trouble, data exchange starts between new main board and service boards without affecting on normal operation of service boards.

Description

technical field [0001] The invention relates to a method for realizing hot backup of a main control board, which belongs to the technical field of data communication. Background technique [0002] In the field of data communication, high-end distributed network devices that play a very important role, such as core routers, often need to provide a backup mechanism, that is, to provide two main control boards, the main control board and the backup one, so that one of them is in working state and the other is in working state. Standby. When the working main control board (hereinafter referred to as the main board) fails, the standby main control board (hereinafter referred to as the standby board) immediately takes over the work of the previous main board to ensure the reliability of the equipment and the network, and at the same time require as little as possible impact on normal business. Therefore, the standby board is required to be consistent with the original active boa...
