【摘要】 天基互联网是开展未来空间新概念业务的基础性网络平台,该文构建了一个通用的天基互联网络管理仿真环境,在仿真环境中对未来空间新概念业务进行辅助开发和演示验证。该仿真环境是一个基于卫星实体仿真的半实物仿真平台,使用一系列基于HLA/RTI的联邦成员,包括空间段仿真成员、星间链路仿真成员、空间协议仿真成员等构成控制网络,对卫星实体进行控制,能够模拟天基互联网的基本特性,能够对天基网络管理及其他新型空间业务进行演示验证。最后,通过该仿真环境,对应用于天基网络管理的类SNMP协议进行了测试。更多还原

【Abstract】 The space-based network is the fundamental platform for new concept aerospace applications,such as network management and aerospace defense.This paper described a general emulating environment for space-based network on which several kinds of new concept aerospace applications can be tested and verified.The emulating environment was built based on the emulating of satellite entities being controlled by the controlling-network.The controlling-network,which consists of the HLA/RTI federates such as STK federate,linking federate,routing federate,can generate and update the corresponding properties of the satellite entities.Through this emulating environment,two kinds of SNMP-like space-based network management protocols were tested.更多还原
