    • A network management system includes a user interface (10), a virtual network (12) and a device communication manager (14). The virtual network (12) includes models (130-135) which represent network entities (30-35) and model relations which represent relations between network entities. Each model (130-135) includes network data relating to a corresponding network entity (30-35) and one or more inference handlers for processing the network data to provide user information. The system can poll or communicate with certain network entities (510, 520, 530, 540, 550) and can infer the status of network connector and other entities (500) for which polling is impossible or impractical. The system performs a fault isolation technique wherein the fault status of the network device is suppressed when it is determined that the device is not defective. User displays include hierarchical location views and topological views of the network configuration. Network devices are represented on the displays by multifunction icons (330, 332, 334) which permit the user to select additional displays showing detailed information regarding different aspects of the corresponding network device.
    • 网络管理系统包括用户接口(10),虚拟网络(12)和设备通信管理器(14)。 虚拟网络(12)包括表示网络实体(30-35)的模型(130-135)和表示网络实体之间的关系的模型关系。 每个模型(130-135)包括与相应网络实体(30-35)相关的网络数据和一个或多个推理处理器,用于处理网络数据以提供用户信息。 该系统可以轮询或与某些网络实体(510,520,530,540,550)通信,并且可以推断网络连接器和其他实体(500)的状态,对于该实体(500),轮询不可能或不切实际。 系统执行故障隔离技术,其中当确定设备没有故障时,网络设备的故障状态被抑制。 用户显示包括分层位置视图和网络配置的拓扑视图。 网络设备通过多功能图标(330,332,334)在显示器上表示,其允许用户选择显示关于相应网络设备的不同方面的详细信息的附加显示。
