摘要
为了保证舰载信息系统数据的高可靠性传输,双冗余网络广泛应用到各种舰载装备中,双冗余网络采用交换机和终端网卡采用热备份模式,形成了从通道到节点的多点冗余。论文提出了一种通过交换机配置优化和终端计算机软件相结合的方法,使一台交换机关机或故障时,双冗余网络切换时间最快可达到ms级。
In order to guarantee the ship_borne information system＇s data is high reliability transmission, the dual_redundancy network is widely used in various shipboard equipment. The switch and terminal network card adopt thermal backup tacit understanding to form muhi-point redundancy from the passageway to the node. In this paper, a dual_redundancy network quick switching method is put forward based on optimization the switeh＇s configuration and computer＇s software,when a switch is shut down or fails, the network＇s switching time can reach ms level.
