Abstract
Description
technical field
[0001] The invention relates to the switching of main and standby devices in a communication system, in particular to a clock and an operation and maintenance monitoring board and a method for switching between main and standby devices. Background technique
[0002] Stability and reliability are essential characteristics of communication equipment. In order to enhance the stability and reliability of the system, it is generally necessary to perform backup operations on key parts of the communication system, which are divided into primary equipment and standby equipment. When the system is working normally, the primary device is enabled; when the primary device fails, the system must quickly switch to the backup device, so that the system can work continuously, and at the same time, the user should not feel the inconvenience caused by the switching of the device.
[0003] According to whether the running state and running data are synchronized between the stan...

Embodiment Construction
[0045] In the clock, operation and maintenance monitoring board and the method for master / standby switching of the present invention, the switched objects are treated differently, wherein the switched objects are divided into the following two categories according to whether the switching needs the judgment and control of the main control software:
[0046] The first type of switching object is information that must be switched by software, such as high-level business information, control information, and operation and maintenance information;
[0047] The second type of switching objects is information that can be switched without software participation, such as system clock information and system synchronization information.
[0048] At the same time, in the clock, operation and maintenance monitoring board and the method for master / standby switching thereof of the present invention, after the main first clock and the operation and maintenance monitoring board fail, the stand...
