海事BGAN网络中安全隔离与信息交换系统设计方案优化

摘要

Aiming at the incapability of real time monitoring the breaks of network with the application of the Safe Separation and Information Exchange system in the communication between land and board, the present design scheme was studied and the disadvantages were improved. Analyzing from the operation principle of the network equipments such as the Safe Separation and Information Exchange system, negotiate transducer and the requirement of network transfering the information, the OPENET software simulation and the performance test were passed, validating the feasibility and effectiveness of the scheme. The new scheme can achieve the function of monitoring the breaks of the network in real time and strengthen the confidentiality of data.%针对安全隔离与信息交换系统在岸船通信应用中,不能实时监测链路通断的难题,研究了现有的设计方案,并改进了其中的不足之处.从安全隔离与信息交换系统、协议转换器、路由器等网络设备的工作原理以及对传输链路的要求等方面分析,并通过OPENET软件模拟、性能测试实验验证了该方案的可行性和有效性,实现了实时监测链路通断的功能,增强了数据的保密性.
