Technical Requirements 4301-MBP-DFCM ：
4301-MBP-DFCM redundancy refers to the repeated configuration of some system components. When the system fails, the redundant components step in and take over the work of the faulty components to reduce the system failure time. Modular redundancy means that the system is composed of a compound modular structure [1]. When a component fails, the structure can be automatically or manually reconstructed, and another component can replace the faulty component to work. The system is degraded and used, except for the faulty component, the rest parts still maintain normal operation.
4301-MBP-DFCM redundancy technology is to add more devices to ensure the reliable work of the system. Modular redundancy refers to layering the system into different functional modules and adopting redundancy technology. When a function module of the system is faulty, redundant function modules are used to replace the faulty module to ensure the normal operation of the system. Modular redundancy is a kind of dynamic redundancy technology, which belongs to hardware redundancy. Dynamic redundancy refers to the use of standard module configuration, once the fault location is detected and diagnosed, the system can be reorganized or recovered, and continue to operate normally.
4301-MBP-DFCM Method for adding certain hardware devices for the purpose of detecting or shielding faults. Common methods are as follows:
One of the methods of hardware fault tolerance is hardware stacking redundancy, which can be obtained at the physical level through the repetition of components (such as string, parallel, quadruple components of the same components, etc.).
Another method of hardware fault tolerance is called standby reserve redundancy. There are a total of M+1 modules in the system, only one of which is in working state, and the other M modules are in standby state. Once the working module fails, it is immediately switched to a standby module, and when the replacement reserve module fails, it is switched to another reserve module until the resources are exhausted. Obviously, such a system must have a device for error detection and switching.
The hybrid redundancy system of 4301-MBP-DFCM is a combination of stacked redundancy and standby reserve redundancy. When one of the modules in the stack redundancy fails, it is removed immediately and replaced with a failure-free standby module. This method can achieve high reliability.
