摘要
从高可用性系统的类型和功能出发，在分析系统失效因素和高可用系统结构的基础上，设计了一个高可用性的软件结构系统，它可以运行于主备、双机和多机3种工作模式，并以有限状态机的状态转移图，具体实现了链路管理和业务接管等关键技术，最后将所设计的软件应用到实际的系统之中，能够很好地满足需求。
On the basis of analyzing the fail-over factors of a system and the structure of high availability system, this paper starts from the types and functions of the high availability system, designs a high availability system software framework, it can be run in three working mode: back-up, hot standby and cluster, then elaborats the implementation of some key technologies: link management and service tack-over, which using finite state machine and the state transfer diagrams. At last, this paper applies the designed high availability system to a network billing system, which perfectly satisfies the system requirements.
