摘要
为了提高调度自动化系统中网络通信的可靠性,提出一种基于双网卡的热备冗余机制。该机制包含了故障监测、故障切换和故障恢复算法。故障监测采用监测程序向核心网络设备发送探测报文的方式;若设备故障则由故障切换程序进行地址的切换;同时监测程序始终保持对故障设备的监视,一旦恢复正常则由切换程序进行故障恢复。文中实现的机制具有实现方便、部署简单、通用性好、可靠性高等特点,在电网调度自动化系统中已得到应用。
In order to improve the reliability of network communication in the power grid dispatching automation system, a hot- standby redundancy mechanism based on dual network interface card （NIC） is proposed. The mechanism consists of fault detection, fault switching and fault recovery. Fault detection information is acquired by sending probe packets to the core network devices. Fault switching program switches IP address when devices are broken down. IP address is switched back when device failure is restored. The hot-standby redundancy mechanism has the characteristics of easy implementation, simple deploying, better generalization and high reliability. The mechanism is adopted in the power grid dispatching automation system.
