摘要
为保证时间服务器系统能够提供不间断授时服务,可采用双机热备技术,结合嵌入式技术和双机热备技术,用AT91SAM9X25嵌入式微处理器作为核心搭建硬件平台,设计了一个基于嵌入式Linux的时间服务器双机热备系统,提高了系统的可用性。实验测试结果表明,系统运行稳定,实现了双机热备。
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 indi- cate that the system is stable, and Hot-Standby is realized.
