摘　　要：为了实现一卫星地面站的网络监控系统的扩容,提高网络监控系统性能,文中利用OPNET对此监控系统进行了一系列的仿真分析,首先确认系统有进一步扩展的能力,然后设计扩展方案,并进一步的仿真分析验证扩容方案的可行性。在仿真过程中,将此系统的业务进行模型抽象,作为一种新的标准应用添加到应用层。这样既满足了系统精确建模的需求又简化了自定义应用(custom application)中繁琐的参数配置。在扩容方案可行性的验证过程中,通过规划设计子观测站系统的拓扑结构、定义其支持的业务,对扩展方案进行了详细的仿真分析,结果表明设计方案可以满足系统的要求。In order to expand the network of monitoring and controlling system at satellite earth station and improve system＇s performance, in the paper, the monitoring system is simulated and analysed with OPNET firstly. It is proved that she system can be enlarged, and then the extended scheme is designed, simulated and analysed in order to validate the feasibility. In the simulation, the system＇ s operation is abstracted condensed and added in the application layer as a standard application, which meets the requirement of precise modeling and simplifies the complex process of parameter allocation in the custom application. The result is analysed detailedly, at the end the result shows that the designed scheme is feasible for the system.
