【摘要】 大型计算机网络地域分布广,网元数目众多,传统网络管理系统以网络拓扑这种虚拟空间的方式实现网络的监控管理,没有充分利用网元的地理位置信息,网络监控和管理存在不便之处。地理信息系统(GIS)的应用能够赋予网络监控管理系统清晰直观、易于监控和管理的特性。通过建立一种基于 GIS 的网络层次化地图模型,系统解决了网络拓扑与 GIS 地图有效结合这一问题,实现了在 GIS 地图中网络拓扑与运行状态信息的层次化管理,给出了网络 GIS 地图的生成、维护的非递归算法。模型和算法的有效性和完备性在大型网络性能监测与分析系统 NIPMAS 中得到了实际验证。更多还原

【Abstract】 Conventional computer network management systems provide a virtual network view, which can not reflect theactual distribution in the space of networks. Applying geographical information system(GIS) to network monitor and management system,an intuitional interface can be given that facilitates the management. A GIS-based computer network hierarchical model is proposed to solve the problem how effectively integrate GIS and network topology, network status information together. Accordingly the model related creation, maintenance, operation algorithms are proposed. And then the model is applied to a distributed network performance monitoring and on-line analysis system, NIPMAS.更多还原
