| Abstract: | Providing incessant time services for time server system, the current solution is the hot standby technique. With embedded Linux and hot standby technology, an time server hot standby system is designed, in which the AT91SAM9X25 embedded micro-processor is used as the key part to build the hardware platform. This function promotes the availability of the system. The experimental results indicate that the system is stable, and Hot-Standby is realized. |
