预定义被管对象层次结构实现分层式运管系统

摘要

针对基于集中式思想请求应答管理模式的SNMP协议无法适应分层式的航天测控网络运行管理体系结构要求的问题,提出预定义被管对象层次结构的方法.通过建立航天测控系统层次定义模型和统一的航天测控网管理信息结构,利用软件实现对SNMP协议的管理站通知报文(GetlnformRequest)的扩展,该扩展报文携带了预定义层次结构,解决了SNMP协议不适应分层式体系结构的问题.结果表明:该方法实现了航天测控运管系统的三层管理结构,使系统的配置工作简化、灵活,满足了航天测控网对网络安全的需求.%For simple network management protocol (SNMP) not adapt to the requirements of layer-type network running management architecture because of its centralized-thought request reply management approach, the paper proposes the method of predefining managed target hierarchical structure. By building the hierarchical defining model and the uniform managerial information structure of space instrumentation and command network, expanding SNMP managerial station GetlnformRequest with the information of predefined hierarchical structure is realized by the software to solve the problem of SNMP not to adapt to the hierarchical architecture. The result shows that the method implements the three-layered management architecture of space instrumentation and command network running management system, and enables the system configuration simple and flexible which meets the requirements of network security of space instrumentation and command network.
