Nowadays most of the VOIP operator committed to building a system with high stability cause communication is the basis of VOIP operation .While VOS3000 operation system can not solve the single point of failure caused by hardware or network . In this case , kunshi network provide hot-standby solution for customers with telecom-carrier-class performance solving the single failure effectively and enabling the business to be resumed as soon as possible. At the same time, data is the core ponent of VOIP operation, if data damaged will cause incalculable losses to customers, thus ,VOS3000 hot-standby solution provide a real-time backup mechanism to ensure data security. VOS3000 hot-standby solution consists of two VOS3000 systems and VOS3000 hot-standby module. Under normal conditions, business runs on the master server as data will be written in it ,meanwhile it will also be written to the slave server in real time. Furthermore ,hot-standby module support real-time verification and synchronization of two servers to ensure the data accuracy . At the same time, system will monitor the running status of the master server in real time. If system can not detect the active status of master server due to network or hardware issues services will be switched to the slave server.After the original master server recovers, it can be re-accessed as the slave server to rebuild hot-standby status again. There are two ways to deploy VOS3000 hot-standby solution : local hot-standby and remote hot-standby with automatic switching and manual switching. This paper is aimed to introduce the basic operation of VOS3000 hot-standby system, such as the principle, construction and switching mode.

VOS3000 support hot standby to ensure no single point of failure in the system. When masterserver failure, services can switch to slave server immediately.Support network traffic, CPU utilization, memory utilization, hard disk real-time monitoring,can find unusual situations rapidly.
