| 摘 要： | 软交换设备的异地容灾是提高网络安全性和提供可靠服务的重要手段，它能够保证系统在某个软交换节点故障的情况下还可以继续提供服务。双归属（Dual Homing）是一个网络拓扑，设备以独立接入点的方式连接到网络。一个接入点是主连接，备用连接在其主连接失败的情况下被激活。主要探讨双归属1＋1互助方式容灾中的一些关键技术，对故障检测，数据同步倒换给出了相应的解决方案。

| Abstract: | The off-site disaster recovery of soft-switching equipment is an important measure for improving network security and providing reliable services, It ensures that the system continue to provide services when the failure occurs in certain soft-switching node. Dual homing（Dual Homing） is a network topology, with device connected to the network at independent access points. With an access point as the principal connection, the back connection would be activated when the principal connection fails. This paper examines some key disaster recovery techniques in dual homing 1＋1 mutually supportive manner. Fault detection; data synchronization switching gives the corresponding solutions for failure detection, data synchronization switching are also given in this paper. |
