摘　　要：针对天地异构网络动态性、高时延以及资源有限等特点,分析现有地面网络管理协议在天地异构网络上应用的可能性,并对比各个网络管理协议的优缺点。在此基础上,进一步分析直接使用传统网管协议带来的一些问题,例如MIB库缺少端到端的时延描述、网络端口流量分析复杂导致不利于网络管理系统对其进行直接观测。最后,结合地面传统互联网网管协议SNMP,提出适用于监测天地异构网络链路状态的方法,主要包括网络拓扑监测、自定义时延测试以及网络流量监控等,为天地异构网络的设计及建设提供参考。Aiming at the heterogeneity,dynamics,high latency and limited resources of space-based network,the possibility of application of the existing terrestrial network management protocol used directly in space-based network had been analyzed,and the advantages and disadvantages of each network management protocol had been compared.Based on the above research,the problems caused by the direct use of traditional network management protocols had been further analyzed,such as the lack of end-to-end delay description in the MIB library and the complexity of network port traffi c analysis,which is not conductive to the direct observation of network management systems.Finally,combined with the traditional network management protocol SNMP,a method suitable for monitoring the links of heterogeneous networks,including network topology,custom test of the delay and network traffi c was proposed.The results of this paper have reference value for the design and construction of space-based network.
