Problems solved by technology
[0004] It can be seen that the currently provided solutions are switched in units of control boards. For example, when the service 2 running on the main control board fails, it is necessary to select a backup board and switch the main control board to the Backup board; that is to say, in the existing solution, if one of the services running on the main control board fails, the entire main control board needs to be switched over to the active / standby mode. In this way, the existing solution It will lead to some unnecessary switching, which greatly expands the scope of influence of the active-standby switchover and increases the complexity of the active-standby switchover

Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the method of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] The method provided by the embodiment of the present invention is applied to an HA system including multiple control boards, each of which has the same structure, including: an HA processing unit, a monitoring unit, and more than one business unit; wherein, the HA processing unit is used for Manage the business units on the same control board; the monitoring unit is used to monitor whether all business units on the same control board are faulty; a business unit is an entity that runs business, and a business unit can run more than one business. It is the service to be processed by the HA system. For example, if the services to be processed by the HA system are business 1 to business 5, each control board can include 3 business...

The invention provides a method and a device for realizing changeover between main and standby services on control panels. The method is applied to a high-availability (HA) system comprising a plurality of control panels; a HA processing unit is selected from HA processing units of each control panel to serve as a main HA processing unit; and the services to be processed are divided into more than one service group. The method comprises the following steps that: A, for each started service, a service unit running the service on each control panel registers the service into a corresponding service group; B, the main HA processing unit determines a main service unit and a corresponding standby service unit of the service group; and C, when the main service unit fails to work, the main HA processing unit determines the standby service unit to be changed with the failed main service unit, so the standby service unit and the failed main service unit are changed over. The method and the device reduce the influence range of main / standby changeover and reduce the complexity of main / standby changeover.
Description
technical field [0001] The invention relates to data communication technology, in particular to a method and device for realizing active / standby switching of services on a control board. Background technique [0002] In the prior art, a high availability (HA: High Availability) technology refers to a technology that improves system availability by shortening downtime caused by routine maintenance operations and sudden system crashes as much as possible. see figure 1 , figure 1 It is a structural diagram of an HA system in the prior art. exist figure 1 In this example, the HA system includes m+1 control boards (specifically, control board 1 to control board m+1). Each control board has the same software and hardware capabilities. For example, if the current services to be processed are services 1 to 5, each control board has the software and hardware capabilities to run services 1 to 5. [0003] When the system is started, one of the m+1 control boards is selected as the...
